Answer: the answer will be astronomy
Explanation:
Which of the following is correctly matched?A. conduction--molecule-to-molecule heat transferB. advection-strongly vertical mixingC. radiation-assimilation and conversion ofD. convection-strongly horizontal mixing
Answer:
A. conduction--molecule-to-molecule heat transfer
Explanation:
A. The transfer of energy through a substance. In heat conduction, energy is transferred from molecule to molecule by direct contact; the molecules themselves do not necessarily change position, but simply vibrate more or less quickly against each other.
B. The option said strongly vertical mixing while advection is the transfer of heat or matter by the flow of a fluid, especially horizontally in the atmosphere or the sea.
C. Radiation is not assimilation and conversion. Radiation is the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
D. Convection is not strongly horizontal mixing. Convection is the transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperature.
If you stacked Avogadro's number of pennies one on top of the other on Earth's surface, how far would the stack extend (in km)? [For comparison, the sun is about 150 million km from Earth and the nearest star (Proxima Centauri) is about 40 trillion km from Earth.]
Answer:
the length of pennies will be like the Proxima Centauri
Explanation:
50 pennies make the length of a meter, so :
50 pennies = 1 m
x = 1 km
x= (50 x 1000) = 50 000 pennies = 1 Km
Then if the Avogadro´s number is 6.022 x 1023 so:
50 000 pennies = 1 km
6.022 x 1023 pennies = x
x= (6.022 x 1023/ 50 000) = 1.2044 x 1019
This big number is closer to the 40 trillion km of the Proxima Centauri.

Even before the proposal of continental drift, paleontologists recognized that some sort of land connection was needed to account for the identical fossil organisms found on multiple continents. Select the correct hypothesis or hypotheses these paleontologists developed.
A) Sea level falling
B) A chain of island stepping stones
C) Floating debris used as rafts and sea level rising
D) A transoceanic land bridge
E) Island stepping stones, transoceanic land bridge, and floating debris used for rafts
Answer:
E) Island stepping stones, transoceanic land bridge, and floating debris used for rafts
Explanation:
It has been found that before the theory of the continental drift the paleontologists recognized the land connect of the various continents of the world that was formed by the multiple fossil and the formed by the transoceanic bridges such as the Bering land bridge, found along the coasts of the Russia and the Alaska and may have been joined by the floating debris that may have been used as raft.During the process of seafloor spreading Choose one:
A. seafloor is neither formed nor destroyed but spreads apart at ridges.
B. new seafloor is formed at ridges and destroyed at trenches.
C. seafloor is neither formed nor destroyed and total seafloor volume stays constant.
D. new seafloor is formed at trenches and destroyed at ridges.
During the process of seafloor spreading, new seafloor is formed at ridges and destroyed at trenches. Hence, option B is correct.
What is seafloor spreading?When the seafloor spreads, tectonic plates, which are huge portions of the Earth's lithosphere, split apart from one another. Seafloor spreading and other tectonic activity processes are caused by mantle convection.
Seafloor spreading is the method by which fresh seabed lithosphere is continuously created along mid-ocean ridges. The Harry Hess-proposed theory has been validated by both the patterns of magnetic field polarity retained in the basalt on the seafloor and the age dating of the rocks.
These days, it refers to the mechanisms by which plates separate and form new oceanic lithosphere. Seafloor spreading significantly affects the chemistry and biology of the planet by repairing the lithosphere that was destroyed by subduction.
Thus, option B is correct.

When a continental plate collides with an oceanic plate, the oceanic plate is forced down towards the asthenosphere in a process known as___________.
Answer:
Subduction
Explanation:
In a convergent plate boundary, two plates move towards each other. The convergence of a continental and an oceanic plate results in the formation of a subduction one, where the denser oceanic plate subducts below the lighter continental plate. The presence of this zone is usually identified by the presence of a narrow depression, commonly known as the oceanic trench. As the plate is forced into the asthenosphere layer, the rocks undergo partial melting, which mixes up with the magma. This magma again rises upward due to the force exerted by the convection current, giving rise to the formation of the volcanoes or volcanic arcs in the over-riding plate.
This process in which the denser plate goes below the less dense one is called the subduction.
Answer:
Subduction
Explanation:
When the two plates collides the thinner and more dense oceanic plate Is forced down in a process called subduction to a much higher temperature Environment.
After a cold front passes, the temperature ________ and the pressure ________ (relative to the conditions that existed prior to the passage of the front).
a. decreases; increases
b. decreases; decreases
c. increases; decreases
d. increases; increases
Answer:
a. decreases; increases
Explanation:
When a mass of cold air is moving in its advance to another mass of warmer air, it is said that we are in the presence of a COLD FRONT. Associated with the passage of the cold front, there is an increase in pressure (a decrease in pressure is previously recorded), wind rotation, decrease in temperature and humidity, improved visibility and elevation of cloud tops.
The passage of a cold front is not always associated with the occurrence of precipitation. Sometimes a mere increase in cloudiness can be evidenced, and in other cases heavy rains or storms.
After a cold front passes, the temperature typically decreases and the pressure increases. This is due to the cold, dense air of the front replacing the warmer, less dense air that was present beforehand, resulting in increased air pressure.
Explanation:After a cold front passes, the conditions typically change in predictable ways. The temperature normally decreases because the cold air from the front takes over, replacing the warmer air that was present before. At the same time, the pressure usually increases. This is because the dense, cold air associated with the front increases the air pressure relative to the conditions that existed prior to the passage of the front.
So, the correct answer is: After a cold front passes, the temperature decreases and the pressure increases (option a).

Convergence along the western margin of North America during the Cenozoic gave way to rifting forces that created the characteristic topography of the ________.
a. Coast Ranges
c. Colorado Plateau
b. Basin and Range Province
d. Columbia Plateau
Answer:
b. Basin and Range Province
Explanation:
Due to the force of the tectonic plates that occurred about the 4.5 billion years, the geology of the North American plate reveals the upwelling a the collision of the plants and thus the western U.S has a rough texture as compared to the smooth central and eastern regions. That has created the 12 main geologic provinces like the Columbia Plateau, the Basin and Range, Colorado Plateau, the Rocky Mountains, and the Laurentian Upland, Interior Plains, and the Interior Highlands. The colorado plateau lies in the upper northern and the central side and the basin and the provinces cover much of the boundaries of the places along the pacific.Geological evidence suggests that many millions of years ago, the Amazon basin drained toward the west rather than the east. What caused this drainage reversal?
a rise in the global sea level
a lowering in the global sea level
the rise of the Andes Mountains
global climate change
Answer:
the rise of the Andes Mountains
Explanation:
Geological studies in the area suggest that the Amazon River originated during the Miocene about 11.3-11.8 million years ago, first as a transcontinental river at a time when present-day South America and Africa were united in western Gondwana. It is believed that it flowed from east to west, and not the other way around.
The elevation of the land and the formation of the Andes towards the end of the Cretaceous, as a result of the clash between the Nazca plate and the South American plate, caused the body of water to become an inland sea that gradually acquired swampy characteristics . About 11 million years ago, water began to flow eastward to the lowlands due to the blockage of the flow caused by the Andes, and flowed into the ocean. Its current form dates back 2.4 million years ago.

The rate of plate movement is only a few ________ per year so climate changes triggered by shifting plates happen on a scale of millions of years.
Answer:
centimeters
Explanation:
The lithospheric plates move relative to the others at a very slow but continuous speed that is, on average, about five centimeters per year. This movement is ultimately driven by the unequal distribution of heat inside the Earth. The hot material found in the depths of the mantle moves slowly upwards and serves as a part of our planet's internal convection system. Simultaneously, colder and denser sheets of the oceanic lithosphere descend to the mantle, moving the rigid outer layer of the Earth into motion. Finally, the titanic friction between Earth's lithospheric plates generates earthquakes, creates volcanoes and deforms large masses of rock in the mountains. But it causes climate changes to be experienced every million years.
Identify the true statement. Choose one: A. The angle of repose is the steepest angle at which unconsolidated sediments can sit without slipping downhill. B. Lahars are mudflows that have been triggered by earthquake shaking. C. Slow movement of unconsolidated material downslope is called a turbidity current. D. The head scarp of a slump is found at the base of the slump block.
Answer:
A. The angle of repose is the steepest angle at which unconsolidated sediments can sit without slipping downhill
Explanation:
The angle of repose is the steepest angle at which unconsolidated sediment can be piled without sliding downward. The angle is also known as critical angle . At this angle the unconsolidated sediments are at the verge of slumping . The angle between the surface of the piled sediments and the horizontal surface is the angle of the repose. At this angle the unconsolidated sediments have reached it limit of accommodating more materials unless it will slump downward.
The make up of the unconsolidated sediments can affect the angle of repose as rounded and fined gained rocks cannot be piled as rough texture d rock materials. The angle of repose can also be affected by the amount of solvents in the sediment. Various rocks sediments possess different angle of repose. Same sediment material can possess different angle of repose if the water contents varies .Example, the angle of repose for sand varies depending on the water contents. The true statement is option A.
The picture above illustrate the angle of repose.

When a volcano erupts, particles of rock and ash are released into the atmosphere. After this, water droplets form around the rock and ash particles and fall to Earth as rain. The rainwater helps plants grow. True or false?
True, volcanic eruptions release rock and ash that can facilitate rain droplet formation; this rain can contribute to plant growth by adding minerals to the soil. Volcanic activities have both immediate and long-term effects on global climate and weather patterns.
Explanation:True, when a volcano erupts, particles of rock and ash are spewed into the atmosphere. These particles can serve as nuclei for water droplet formation, leading to precipitation. Once this volcanic ash-laden rain falls, it can indeed help plants grow, as the materials from the volcanic ash can contribute valuable minerals to the soil, enhancing its fertility.
Volcanic eruptions function as a natural driver of climate change, releasing gases and solids that influence climate over a period of years. Besides water vapor, these emissions include carbon dioxide, sulfur dioxide, and other greenhouse gases. Nevertheless, eruptions typically result in a short-term cooling followed by longer-term impacts on weather patterns and climate.
While the immediate aftermath of a volcanic eruption is hazardous, the release of volcanic ash and gases has shaped Earth's atmosphere and climate over geological time spans. The water cycle, consisting of evaporation driven by the Sun and precipitation influenced by gravity, plays a pivotal role in returning water from the atmosphere back to Earth's surface, replenishing ecosystems and aiding in plant growth.

The dissolved materials in seawater are thought to originate from chemical weathering of rocks on the continents and also from ________.
a) benthonic.
b) plankton.
c) out-gassing of elements from Earth's interior.
Answer:
Option (C)
Explanation:
The out-gassing is usually defined as the process by which gases such as carbon dioxide, water vapor, sulfur dioxide, and nitrogen are released during the release of pressure from the earth's molten rocks. This process takes place due to the increase in temperature. These gases are responsible for the formation of the atmosphere over millions of years.
Thus, the dissolved materials that are found in the seawater are mainly originated from the out-gassing of elements from the interior of the earth and also from the chemical weathering of rocks on the continents.
Thus, the correct answer is option (C).

Assuming that the long term rate of displacement along the San Andreas Fault (about 3.5 cm/year) remains the same and that the location of the fault remains the same, how long would it take Los Angeles (on the west side of the fault) to move north 620 kilometers to the position of San Francisco (on the east side of the fault)?
Answer:
17.71 years
Explanation:
As the crust of the San Andrea is continuously moving due to the tectonic activity and is the main manifest of the tectonic boundary of the North America and the pacific plate. This fault along with the pacific plate will move towards the Los angles and eastern San Francisco as it moves about 3.5 cm per year. As 1 km equals to about 100 000 cm , then the distance of 620 km = 62, 000,000 cm and 62,000,000 will be divided by 3.5 equal to 17. 71 years to collide with the eastern side.It would take approximately 17.7 million years for Los Angeles to move to the position of San Francisco along the San Andreas Fault if the rate of displacement remains constant at 3.5 cm/year.
To calculate how long it would take for Los Angeles to move north 620 kilometers to the position of San Francisco at a rate of 3.5 cm/year along the San Andreas Fault, we need to convert the distance to the same units used for the rate of displacement and then divide the distance by the rate. The displacement in centimeters is 620 km × 100,000 cm/km = 62,000,000 cm. Then, divide the total displacement by the rate of movement:
62,000,000 cm ÷ 3.5 cm/year = 17,714,285.7 years
So, it would take approximately 17.7 million years for Los Angeles to move to the position of San Francisco, assuming the rate of movement stays constant along the San Andreas Fault.

You decide to study two species of birds, both of which form monogamous pairs (one male and one female). In species 1, the eggs in a pair's nest are almost always the offspring of that pair. In species 2, many of the eggs in a nest were actually fathered by males of neighboring pairs. Apparently, mating outside of monogamous pairings is widespread in species 2. What would be the logical prediction to make before comparing the testes size of males of the two species?
Answer:
B-Testes of species 2 are larger than testes of species 1.
Explanation:
Relatively bigger tests are associated with female and/or male promiscuity across a wide range of invertebrate and vertebrate taxa.
Short 1979; Harcourt et al. 1981;
Two general theories to explain the interspecific difference in test size were proposed: 1) sperm competition (Parker 1970) and 2) sperm depletion (Short 1981). Data available suggest that sperm competition in the evolution of the size of avian testes may be a more important selective force than sperm depletion. As a result, species-specific test size data were used in comparative studies, particularly of birds, as a convenient and supposedly reliable index of sperm competition levels which further leads to bird promiscuity.
Which of the following does not determine species' range limits? a) the substrate. b) latitude. c) altitude d) disturbances such as fire. e) all of the above play a role in determine a species' range.
Answer:
Option (E)
Explanation:
A species range is usually defined as the geographical area where any group of particular species dwells during its entire life span. This range of species includes those areas of species migration as well as hibernation.
The range of these species are controlled by different factors such as latitude (such as tropical and polar zones that are marked by vast difference in terms of temperature), heights (like high mountain ranges and plateaus), substrate (a place on which or from where an organism grow), climate ( as it differs from one place to another). In addition to this, forest fire also occurs in the forests that destroys the habitat of these species, and their range of existence is affected.
Thus, a species range is controlled by all the above-given factors.
Hence, the correct answer is option (E).
Final answer:
All the given factors, including substrate, latitude, altitude, and disturbances like fire, do play a role in determining a species' range limits. Changes in biomes on a mountain hike are caused by elevation, rainfall, and temperature, but not by changes in latitude as one ascends.
Explanation:
The substrate, latitude, altitude, and disturbances such as fire all play a role in determining a species' range. Therefore, the answer would be e) all of the above play a role in determine a species' range. It's important to recognize that an ecologist might observe changes in biomes due to various factors like elevation, rainfall, and temperature, but not latitude since this does not change as one hikes up a mountain.
Geographical constraints, physical barriers, climate, and even factors like soil composition and human-induced changes, such as dams, can influence where a species can live and thrive.
Alternating parallel bands of normal and reversed magnetic polarity are found in the basaltic bedrock on either side of 1. the Mid-Atlantic Ridge 2. Yellowstone Hot Spot 3. San Andreas Fault 4. Peru-Chile Trench
Answer:
1. the Mid-Atlantic Ridge
Explanation:
The Mid-Atlantic Ridge is a mid-ocean ridge that extends into the South Atlantic Ocean between the South American and African Plates.
Alternating parallel bands of normal and reversed magnetic polarity is found here because basalt contains little magnetic particles that take on the direction of the Earth’s magnetic field at the time of eruption.
These bands are like stripes which shows up on the ocean floor when these variations are mapped.
Smaller cities located on the edges of a larger city which often include residential neighborhoods for those working in the area are called_________
Final answer:
The term for smaller cities located on the edges of a larger city, which are more economically complex and include both residential and commercial areas, is known as an 'edge city'.
Explanation:
Smaller cities located on the edges of a larger city that include residential neighborhoods for those working in the larger urban area are known as suburbs. However, the specific term for areas that are more economically complex, often including not only residential areas but also office buildings, shopping and entertainment districts, and even factories, is an edge city. Edge cities are typically found at the intersection of major highways and serve as high-density business districts, sometimes referred to as suburban downtowns. They emerged significantly as commercial hubs in the 1970s, powered by affordable land, efficient highways, and an ample workforce, marking a shift in urban development patterns with many businesses and fewer residents as compared to traditional suburbs.
