Answer: B. Original Continuity
Explanation:
Original continuity is the concept that sediments are deposited horizontally at the original point of formation. This lateral deposit continues, layer by layer unless the sediments are interrupted by a barrier.
The two rocks on the opposite sides of the canyon were likely one body of rock due to their similar lithology and fossil content. It is likely that the canyon formed due to erosion over time, thereby creating a barrier between the rocks.
The idea that two bodies of rock on opposite sides of a canyon with identical lithology and fossil content were likely physically connected at one time is summarized by the principle of original continuity, also known as the principle of lateral continuity.
Explanation:If the lithology and fossil content of two bodies of rock on opposite sides of a canyon are identical, then these remaining outcrops were likely physically connected at one time and formed part of an extensive, sheet-like layer of rock. This idea summarizes the principle of original continuity.
The principle of lateral continuity suggests that layers of sedimentary rock were once continuous, and anything that interrupts the layer (like a river or canyon) occurred after the rocks were deposited. This principle is employed when geologists compare seemingly similar groups of rocks separated by some distance. They can infer that rocks on either side of a canyon were, in fact, the same and were once connected before the canyon formed. Thus, identifying identical lithology and fossil content across these divides provides evidence for this continuous nature prior to any geological separation.

Answer:
A spiral galaxy.
Explanation:
This is a class of galaxy described in 1936 by the American astronomer Edwin Hubble.
The central bulge is characteristic of this type of galaxies, where the major concentration of stars resides. The "arms" are very bright and are full of young, blue stars.
The pinwheel shape is why we can easily recognize them from the earth. Astronomers think that more than 60% of the galaxies in the universe are spiral-like.
The atmospheric cooling that occurs where and when aerosol pollution is the greatest is an example of:
Answer:
Aerosol effects
Explanation:
Aerosol effects
Aerosol is a small packets of air that remain in the atmosphere.
We know that the sun is the major source of energy on the earth but it is not true that we receive all that energy. some portion of that energy is either absorbed by aerosol or clouds . therefore it keep the temperature of earth little cool. However some aerosol also reflect the sun energy and this depends on solely on the composition of particle that make aerosol.
From the information given below, which city has the highest relative humidity?
Urbana, IL: T = 52F, Td = 32F St. Louis, MO: T = 69F, Td = 46F Milwaukee, WI: T = 22F, Td = 21F (difference) Austin, TX: T = 90F, Td = 40F
a.Urbana
b.St. Louis
c.Milwaukee
d.Austin
Answer: c. Milwaukee
Explanation:
The warmer the air gets, the higher its capacity for water vapor. Thus, the relative humidity would increase as the dew point temperature decreases and vice versa. The relative humidity is usually highest at sunrise at the point when the overnight low temperature is usually close to the dew point.
Since Milwaukee has the lowest Td = 21°F and its R.H = 51.358, a value higher than the rest since the rest have negative values.
Final answer:
Milwaukee, WI, has the smallest difference between the temperature and dew point, indicating it has the highest relative humidity among the listed cities.
Explanation:
From the given data, the city with the highest relative humidity must be determined by comparing the temperature (T) and the dew point temperature (Td) of Urbana, IL; St. Louis, MO; Milwaukee, WI; and Austin, TX. Relative humidity is closely related to the difference between the actual air temperature and the dew point temperature. A smaller difference between these temperatures indicates higher relative humidity, as the air is closer to being fully saturated with water vapor.
Urbana, IL: T = 52°F, Td = 32°F (difference = 20°F)
St. Louis, MO: T = 69°F, Td = 46°F (difference = 23°F)
Milwaukee, WI: T = 22°F, Td = 21°F (difference = 1°F)
Austin, TX: T = 90°F, Td = 40°F (difference = 50°F)
Given this analysis, Milwaukee has the smallest difference between the temperature and the dew point, indicating it has the highest relative humidity among the listed cities, making the correct answer (c) Milwaukee.
The slow drifting of sections of the earth's crust, sometimes separating, other times colliding, is known as ________.a. plate tectonicsb. crust dynamicsc. continental divergenced. continental convergence
Answer:
a. plate tectonics
Explanation:
plate tectonic theory describe the fact that the earth is divided into different thick plates(crust) that moves slowly and change in sizes. This plates drift away from each other , slides past another or even collide with each other . The resulting movement of this plates brings about the uneven configuration of the earth crust. Some part of the earth are been subducted while some are uplifted resulting to mountain belts and hills. The plate tectonic idea was born out of the theory of continental drifting and seafloor spreading.
continental drifting talks about the movement of the continents on the earth surface . it is believe that the continents changes position in relation to one another. Sea floor spreading is the idea that the sea floor drift away from each other into two parts with the mid oceanic ridge forming the mid points . As you move away from the mid oceanic ridges the floor becomes increasingly older in age.
Generally, plate tectonic plays a major role on how the earth looks, the structures that are formed and the rocks formed.
All continents fit together with the least number of overlaps and gaps when the continents are matched along:________
A) contours at around 2,000 meters depth.
B) current shorelines.
C) edge of the continental shelf.
D) edges of the deep sea floor.
E) oceanic trenches in subduction zones.
Answer:
A) contours at around 2,000 meters depth.
Explanation:
As the contours of the world when measured from a 2000 meters depth shows us the same orientation and fitting f the continental shelf sand the plates as the lines joined the place as they are then overlapped and hence are connected by the values that are assigned to them.Final answer:
All continents fit together with the least number of overlaps and gaps along the edge of the continental shelf, which is the underwater extension of the continent before the continental slope.
Explanation:
The continental shelf is the ocean floor nearest the edges of continents, characterized by a gentle slope and shallow waters, usually extending about 100 to 200 kilometers from the shore up to the shelf break. This feature represents where the continental crust continues underwater before reaching the steep continental slope.
While options such as contours at around 2,000 meters depth, current shorelines, edges of the deep sea floor, and oceanic trenches may seem plausible, they do not represent the precise match points that existed when the continents were once connected. Oceanic-continental convergence, which shapes features like trenches and submarine canyons, occurs at plate boundaries but is not where continents would seamlessly connect.
Which of the following geological processes adds new rock to the surface of the earth?
A) Volcanic activity
B) Glacial activity
C) Soil erosion
D) Weathering
Answer: A) Volcanic activity
Explanation: Volcanic activity which includes volcanic eruptions is a high temperature process through which rocks such as metamorphic rock melts through large scale earth movements and transportation its it's Magma materials into another location adding new rocks.
Volcanic activity is a geological process which add new rocks to the Earth,the other options involved breakdown processes which doesn't add new rocks.
Glacial activity involves the melting of ices due to high temperature.
Soil erosion is the movement of soil particles caused by mainly by water movement,air etc.
Weathering is the breakdown of rocks into small pieces.
Which of the following is NOT an ecosystem service provided by pristine forests? a. prevention of soil erosion b. removal of air pollution c. moderation of climate d. land for agriculture
Answer:
d
Explanation:
Pristine forests do not provide the ecosystem service of land for agriculture because converting forests into farmland requires anthropogenic activities, which result in environmental issues like deforestation and climate change.
Explanation:The ecosystem service among the options that is NOT provided by pristine forests is option d. land for agriculture. Pristine forests, by their very definition, are untouched and unspoiled by human activities, including agriculture. While forests provide critical ecosystem services like prevention of soil erosion (option a), removal of air pollution (option b), and moderation of climate (option c), they do not naturally provide land for agricultural use. Any conversion of forest land into agricultural land typically comes with negative impacts such as deforestation, which leads to a reduction in habitats for numerous species, buildup of greenhouse gases, soil erosion, and a disrupted local climate.

If a basalt body cuts across a fault, what are the relative ages of the basalt and the fault?
a. The fault must be older, according to the principle of cross-cutting relationships.
b. The basalt must be older, according to the principle of cross-cutting relationships.
c. The basalt must be older, according to the principle of original horizontality.
d. Their relative ages cannot be determined from the information given.
Answer:
Option (B)
Explanation:
According to the law of cross-cutting relationships, in a geological feature where an igneous rock body is intruded by any intrusive body such as a fault and d(i)kes, then the intrusive bodies are considered to be younger than the surrounding igneous rock.
In the given condition, the basalt is the older surrounding rock which is being cut across by a fault, and this follows the principle of cross-cutting relationship.
Thus, the correct answer is option (B).
True or false?
The growth rate of a certain population increases very quickly for a time and then levels off to zero. The most likely reason that the growth rate leveled off to zero is that the population reached the carrying capacity of that environment.
Answer:
It is True.
Explanation:
This statement is true because this statement tells us a very rational point of view as well as a fact that the growth of population increases very quickly for a certain point then after that it growth drops to zero. The reason for the drop in the growth to zero is due to the many factors which is explained by the term "Carrying Capacity of Environment".Carrying Capacity of an environment is very crucial for the people living in that environment. It is basically measure of the ability of the ecosystem to sustain itself by providing basic needs to maximum number of the human beings. The basic needs include shelter, food, water etc.When a carrying capacity is reached, then its means that the maximum people are getting basic needs from the ecosystem. Then further increase in population results in the deficiency of the resources for food, water, shelter etc so, as a result that result in the decrease of population due to competition of survival and other factors.Albedo is the tendency of a surface to reflect solar energy instead of absorbing it, and snow and ice have a much higher albedo than water. Over the last several decades the amount of the Arctic Ocean that has ice on it has been decreasing, thereby exposing more and more of the Arctic Ocean to the atmosphere each summer. Would this cause the total absorption of heat in the Arctic to increase or decrease?
Answer:
increase
Explanation:
The depletion of the ice sheets in the Arctic Ocean will expose more of the ocean to the incoming solar energy. Because water has a much lower albedo than ice, it absorbs more energy and so takes in more heat than did the sea ice. The net result is increased heat absorption and further loss of sea ice in the Arctic region.
Directly seaward of the continental shelf is a more steeply sloping region called the: mid-ocean ridge. continental rise. trench. abyssal plain. continental slope.
Answer:
Continental slope
Explanation:
Continental slope is known as the boundary (usually seaward) of a typical continental shelf. This is also the region that is located seaward and extends at approximately 2890 to 3980 m. The continental shelf also stands as a separation between the ocean and a continental self. Therefore, based on the description, the correct is continental slope.
Major oceanic surface currents travel ________. A. parallel to the prevailing wind direction in a region B. in direct opposition to prevailing winds as a result of the Coriolis effect C. at an angle to prevailing winds as a result of the Coriolis effect D. at an angle to prevailing winds as a result of the Doppler effect
Answer: B - in direct opposition to prevailing winds as a result of the Coriolis effect
Explanation: Surface oceanic current form gyres which are large circular patterns. It flows in opposite direction which means it flows in a clockwise manner in the Northern Hemisphere and flows in an anticlockwise manner in the southern hemisphere.
Surface oceanic current flows in a regular pattern which can be shallow and wide or deep and narrow.
It also carries heat from place to place in the earth system.
Oceanic surface currents travel at an angle to prevailing winds due to the Coriolis effect, which is caused by the rotation of the Earth.
Explanation:Major oceanic surface currents travel C. at an angle to prevailing winds as a result of the Coriolis effect. The Coriolis effect, prompted by Earth's rotation, causes the paths of these currents to bend rather than follow a straight path. Instead of flowing directly from high to low pressure areas (as they would in a world without rotation), the winds and currents deviate towards the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

A portion of a plate with continental crust composing its uppermost layer is thicker than one bearing ____________________ crust
Answer:
A portion of a plate with continental crust composing its uppermost layer is thicker than one bearing Oceanic crust
Explanation:
The continental crust which is the uppermost layer of the lithospheric plate is thicker and less dense than the oceanic crust because of the constituent that makes up the crust. The continental crust is mainly compose of granitic rocks.
The oceanic crust are more dense and thinner than the continental crust . The oceanic crust is mainly composed of Mafic rocks like the basaltic rocks . And the high density nature of the oceanic crust contribute to it less active nature if it collides with the continental crust . when it collides with the continental crust it tends to subduct.
The oceanic crust has a thickness of about 70 km while the thickness of the continental crust ranges from 125 km to 250 km . Rocks found in the continental crust are usually more older than the rocks found in the oceanic crust because in the oceanic crust newer crust are been formed around the oceanic ridges while the older rocks are subducted in trenches.
Which statement about local and global winds is true?
a. Local winds blow from the poles to the equator, whereas global winds blow west to east.
b. Local winds curve due to the Coriolis effect, whereas global winds blow in a straight path.
c. Local winds blow over long distances, whereas global winds blow over short distances.
d. Local winds blow over short distances, whereas global winds blow over long distances.
Answer:
Option (D)
Explanation:
The local winds are generally described as those that blow for a relatively shorter distance. These wind can blow in any particular direction and are not affected by the earth's rotation. This includes the land breeze and sea breeze.
On the other hand, the global winds are usually defined as those that blow over a large geographical area and are commonly affected by the earth's rotation, where the Coriolis force pushes the wind to move in the clockwise and anticlockwise direction in the northern and the southern hemisphere respectively.
Thus, the correct answer is option (D).
Answer:
D - Local winds blow over short distances, whereas global winds blow over long distances.
Explanation:
Local winds blow from the poles to the equator, whereas global winds blow west to east. Local winds curve due to the Coriolis effect, whereas global winds blow in a straight path. Local winds blow over long distances, whereas global winds blow over short distances.
Identify the TRUE statement. Choose one:
A. Our Sun is the only star we know of that has planets associated with it.
B. The only two planets with moons are Earth and Jupiter.
C. The Sun accounts for almost 50% of the Solar System's mass.
D. The composition of the giant (Jovian) planets is mainly gas and ice.
Answer:
D. The composition of the giant (Jovian) planets is mainly gas and ice.
Explanation:
Giant planet that is not composed mostly of rock or other solid matter but of fluids (gas and ice); although said planets may have a rocky or metallic core. It is believed that such a nucleus is probably necessary for a gas giant to form, but most of its mass is in the form of gas, or compressed gas in a liquid state.
Unlike rocky planets, gas giants do not have a well defined surface. Terms such as diameter, surface area, volume, surface temperature or surface density can refer to the outer layer seen from outside, for example from Earth.
In the Solar System there are four gas giants: Jupiter, Saturn, Uranus and Neptune. These planets are also known as the "Jovian planets." Uranus and Neptune have been considered by scientists as a separate subclass of giant planets, frozen giants, also called "uranium planets", due to their structure mainly composed of ice, rock and gas. They differ from "traditional" gas giants, such as Jupiter and Saturn, because their proportion of hydrogen and helium is much lower, mainly because of their greater distance from the Sun.
Why are structures built on soft sand or mud often destroyed in an earthquake when nearby structures built on bedrock remain essentially undamaged?
Answer: An earthquake is the shaking of the surface of the earth caused by volcanic activity or movement around geological faults.
Earthquakes can be of a high magnitude or low magnitude. (magnitude is the size of the earthquake or the frequency of the vibrations caused by the earthquake.)
Earthquakes shakes with stronger vibrations in soft sand or mud that's why structures built on soft sand or mud are often destroyed in an earthquake.
Earthquakes shakes with small vibrations on bedrock because of the rigidity of the bedrock.

Economically speaking, what has been the trend in East Asian countries over the past six decades?
Answer:
B) their economies have shifted from agriculture to manufacturing
Explanation:
East Asian countries moved into manufacturing. Many companies from High-Income Countries (HICs) began to manufacture products in Asia due to the low cost for labor, land and resources. This was only increased by the reliability and technological developments by transport options. Urbanization happened faster as the agricultural industry needed less labor intensive workers and more machine operated farming equipment on a commercial scale. The populations also rose dramatically and the labor prices stayed down.
All true oceanic islands are ________ in origin.
A) volcanicB) collisionalC) sedimentaryD) erosionalE) metamorphic
Answer:
A) volcanic
Explanation:
Oceanic island are formed where their is volcanic eruption on the sea floor . This island rises above the sea water and can experience active volcanoes overtime.
This island are formed when the oceanic plates collides with the more active continental crust. Example of this island is the Aleutian Island. The oceanic crust been denser, subduct under the more active and less dense continental crust. This subduction brings about crustal migration of molten magma from the earth interior .
This molten magma due to pressure may erupt through the vents on the sea floor to form oceanic islands . Generally, this eruption build up to form new crust and invariably form a volcano on the seafloor. This is why most oceanic islands are volcanic in nature . And this island are also called volcanic Island.

It burned in a fire set off by broken gas lines. all of the above
Answer:
The correct option is:
A weak, subsurface, clay layer failed, resulting in numerous landslides.
Explanation:
In 1964, the earthquake in Alaska damaged the Turnagain Heights and this earthquake was the strongest earthquake in the USA that was recorded. The magnitude was of about 9.2 on Richter Magnitude Scale.The statement is valid for the damage of Turnagain Heights which says that "A weak, subsurface, clay layer failed, resulting in numerous landslides." as it was the primary cause.The statement "It was hit by a large tsunami and then buried by a rock avalanche" was not the reason of it. The earthquake led to the Tsunami which increased the scale of destruction.The statement " It burned in a fire set off by broken gas lines." is also not valid as it was not cause of damage of Turnagain Heights. The gas lines broke due to the earthquake.Which of the following climate conditions would most likely allow glaciers to form?
a. temperatures below freezing for one month straight
b. mild winters with lots of snow coupled with very hot summers
c. high winds that produce low chill factors
d. a heavy snowfall in winter cou
Answer:
Three conditions are necessary to form a glacier: (1) Cold local climate (polar latitudes or high elevation). (2) snow must be abundant; more snow must fall than melts, and (3) snow must not be removed by avalanches or wind
Explanation:
For glaciers to form, cold climates where temperatures remain below freezing for extended periods are required, allowing for the accumulation of snow that compacts into ice over time. Option 'a' suggests sustained low temperatures, which aligns most closely with glacial formation conditions, but in reality, these conditions need to extend beyond just one month.
The formation of glaciers requires specific climatic conditions. The most crucial factor is temperature, which must be low enough to allow snow to accumulate over time without completely melting during the warmer months. For glaciers to form, we're typically looking at areas with cold climates, where the temperature remains below freezing for extended periods, allowing snowfall from winter to endure through the summer, gradually compacting into ice.
Among the options provided, a process of glacier formation is most likely in conditions where there are:
Persistent low temperaturesSufficient snowfall to exceed summer meltingClimates such as the polar (Fi and Ft types) and subpolar where these conditions are metConsidering the ecological setting that promotes glacier formation, option 'a. temperatures below freezing for one month straight' is the closest, but true glacial formation typically requires such conditions for much longer periods. This would be more consistent with the descriptions of the polar and subpolar climates, where temperatures remain below or just above freezing for the significant part of the year.
The type of marine sediment that forms the thickest deposits worldwide is:
a. neritic siliceous sediment deposits.
b. neritic coarse lithogenous sediment deposits.
c. abyssal clay deposits.
d. manganese nodule deposits.
e. pelagic biogenous calcareous deposits.
Answer: b. neritic coarse lithogenous sediment deposits.
Explanation:
Sediments are formed from different sources, both terrestrial and aquatic and are deposited by the movement of water, glaciers and wind. The type of deposits formed from erosion of terrestrial materials are known as Lithogenous sediments. The range in size from fine to coarse particles.
Neritic and Pelagic refer to different depths in an ocean. While neritic refers to the area close to the coast, Pelagic refers to the the deep ocean. Neritic, coarse lithogenous deposits are found on shallow ocean floor s as well as along the coast, and make the thickest deposits worldwide.
Judge the following sentence according to the criteria given below: The melting of Arctic sea ice by rising temperatures is an example of a negative-feedback loop BECAUSE the lack of ice cover will result in the Arctic Ocean absorbing more of the Sun's radiation.
Answer:
YES, the positive feedback leads to the instability and the negative feedback leads to the stability.
Explanation:
The melting of the glacier ice is an example of the negative feedback as it being a balance in the amount of the ice and the temperature extremes and therefore is a proper way to check the ice cover and thus he arctic ocean will be balanced by the absorption of the sun heat and the leads to the reduction in the temperatures in the nearby lands. And it's a natural cyclic system of the earth.Why are most of Earth's deserts located in the subtropical zone?
A. These regions receive more sunlight than the equatorial region.
B. These regions receive less sunlight than the equatorial region.
C. These regions are very warm but less humid than other regions.
D. These regions are very warm but more humid than other regions.
Answer:
C) These areas are very warm but less humid than other regions.
Explanation:
It is an area of high atmospheric pressure. This means that cold air is descending and will return to the lowest pressure, towards the equator. The air is dry and rarely forms clouds as it is descending. This allows for a maximum of incoming solar radiation to heat the ground surface. The air moves towards the equator becoming more humid and rise, which helps provide rain for the rainforest. By the time it reaches the desert area it is once again dry and descending.
These regions are very warm but less humid than other regions.

Explanation:
It is large emplacement of igneus intrusive rock (plutonic rock) . It forms from cooling magma deep in Earth´s crust. They may have a uniform appeareance, but their structure is really complex.
Answer:
a. batholith
Explanation:
Granite is an example of igneous rocks . Igneous rocks are rocks formed through the cooling of molten magma or lava. Lava's are molten magma that creeps or erupt to the surface of the earth crust before cooling.
Igneous rocks can be extrusive or intrusive igneous rocks. Extrusive igneous rocks are formed when lava cools rapidly at the surface of the earth to form the rocks while the intrusive igneous rocks are formed when molten magma cools at the interior of the earth crust .
Granite is an example of intrusive igneous or plutonic rocks that are formed from the crystallization of molten magma slowly cooling below the earth surface. The formation of this rocks are slow due to the high temperature available below the earth surface . Granite rocks are plutons .
Plutons are large bodies of intrusive igneous rocks that are usually coarse grain formed at the interior of the earth. A large congregation of plutons are known as batholith.
Generally, Batholith is a very large mass of intrusive igneous rocks forms below the earth crust. The granite dome in Yosemite National park in California has a very large amalgamation of this plutons known as batholith.
"The rock surface in this photo has been eroded by a glacier. The erosive pattern shows long, parallel grooves in the rock that are called"
Answer:
Striations- As they are the scratches and erosive patterns which are formed on the bed rock due to the glacial abrasion."
Explanation:
Now, in the early times or many millions years ago the glacial layers passed through different regions of the land, leaving marks behind. Some of these marks can be analyzed as the parallel grooves in the rock called as striations.
The glacial abrasion is the process during which the bottom rocks are glided over the layer of the land, creating different patterns on it called as striations.
