a) actual date of an event
b) length of time between events.
c) age of one event in comparison with other events.
d) rate at which a geologic process occurs.
Answer:
c) age of one event in comparison with another
Explanation:
The relative dating is a commonly used method among the geologists, paleontologists, and archaeologist. This method is used for determining the order of events that happened in the past, or rather the age of an object in comparison with another object. This also means that it is not necessary for this purpose to determine the absolute age of the objects, but instead the age of one one of them is compared with another one, and we get to the relative dating of an object that is required.
How are elements that are heavier than hydrogen spread throughout the universe?
please and thanks!
Answer:
The early stars are massive and short-lived. They consume their hydrogen, helium and lithium and produce heavier elements. When these stars die with a bang they spread the elements of life, carbon and oxygen, throughout the universe. New stars condense and new planets form from these heavier elements.
Explanation:
Heavier elements than hydrogen are distributed throughout the universe by nucleosynthesis in stars and their expulsion into the interstellar medium through supernovae, leading to progressively richer generations of stars in heavy elements.
Elements that are heavier than hydrogen are spread throughout the universe primarily through the process of nucleosynthesis within stars and the subsequent distribution of these elements when stars reach the end of their lifecycle.
At the start of the universe, only the lightest elements like hydrogen, helium, and some lithium were created by the Big Bang. As the universe expanded and cooled, these elements formed the first stars. Inside these stars, through nuclear fusion reactions, heavier elements up to iron were produced, especially in stars with more than 8 solar masses.
When massive stars exhaust their energy supply, they often undergo supernova explosions, scattering their enriched material into the interstellar medium. This debris, containing heavier elements, then becomes part of the building material for new stars and planets.
Over time, each generation of stars has become richer in heavy elements, explaining why open-cluster stars have more heavy elements than older globular clusters. This is how elements heavier than hydrogen have been distributed across the universe and are found even in the composition of Earth and in our own bodies.
If it is __________ in the Northern Hemisphere, then it must be __________ in the Southern Hemisphere.
Answer:
summer - winter... or vice versa
Explanation:
The seasons on the two opposite hemispheres are opposite to each other. When the Northern Hemisphere experiences summer, the Southern experiences winter, and when the Norther Hemisphere experiences winter, the Southern Hemisphere experiences summer. The reason why the seasons are opposite on the two hemispheres is the tilting of the Earth. In one part of the year, the tilting of the Earth exposes the Northern Hemisphere more to the sun, thus it is heated more and it it summer there, while the Southern Hemisphere is tilted away from the sun, so it receives less heat, so it is winter there. The opposite happens in the other part of the year, as the Southern Hemisphere is the one that is more exposed to the sun and experiences summer, while the Northern Hemisphere is tilted away from the sun so it experiences winter.
Climate determines all of the following except __________. A. the price of produce B. the amount of production C. what products are cultivated D. where agriculture is produced
Answer: A
Explanation: All the rest are correct!
Answer:
A. the price of produce
Explanation:
As the climate of a place remains static for a longer time period and thus the production of the commodity depends on the climatic characteristics of the place. Hence the price remains to be unaltered by the climatic parameters of the place and thus the amount of the product and the product to be cultivated gets affected by the availability of the rainfall and the duration of the sunshine. But the price is an economic factor and cannot be directly estimated by the values of the physical parameters.Which type of seismic waves result from interference between S waves and P waves?
A. Rayleigh waves
B. Rayleigh waves and Love waves
C. Dispersive waves
D. Love waves
It’s A Rayleigh waves
Answer:
The seismic waves that result from the interference of P and S waves are the Rayleigh waves.
Explanation:
Both the P waves and the S waves fall in the category of body waves that travel through the interiors of Earth. Because the P waves travel about 60% faster than the S waves, they reach to the surface of the Earth before the S waves do. The S waves follow the P waves to reach the surface and create a rolling effect like that of sea waves. This interference of the P and the S waves results in the formation of Rayleigh waves.What process is responsible for creating magnetic changes along mid-ocean ridges? A. Ridge push B. Slab pull C. Seafloor spreading D. Reversal of Earth's magnetic field
Answer:
D. Reversal of Earth's magnetic field
Explanation:
The earth's magnetic field changes over time and this causes changes in the direction of magnetization of magnetic elements or minerals in rocks.
Our magnetic field is widely believed to originate from activities within the outer core where molten iron and nickel moves. The flow of these molten elements results in the production of the magnetic signatures on earth surface.
Some elements and minerals within rocks are capable of recording the direction of magnetic fields at a period in time. Before magma cools, such minerals in these rocks aligns their poles to that of the prevailing direction of the earths magnetic field. This is how the magnetic changes at the mid-oceanic ridges are recorded.
Answer:
The process of seafloor spreading is responsible for "creating magnetic changes" along mid-ocean ridges.
Explanation:
When "seafloor spreading" occurs along the mid-oceanic ridges, it results in a drastic splitting of the oceanic floor over a large area. This in return changes the orientation of the predominant magnetic fields and the intensity of their strength in the region. The mid-oceanic ridges are majorly constituted of solidified lava which is rich in iron. The changes that occur in the local magnetic fields due to seafloor spreading thus create magnetic changes along the mid-oceanic ridges.The arctic tundra is different form the alpine tundra becauses it has ___.

Q. what do you by "regulates intervald"
: Intervald : thats for this one
Final answer:
In Indian railways, 'regulated intervals' refers to the pre-set schedules that trains follow on single tracks to avoid collisions and ensure smooth transit. This system requires precise timing and controlled train movements, a practice that has evolved to meet the demands of safety and efficiency on the railways.
Explanation:
In India, there are three types of railway gauges: broad, metre, and narrow. When broad gauge lines are referred to as double track, it means trains can ply on two sets of railway lines at all times, allowing for continuous traffic flow in both directions. Conversely, on single tracks, trains ply only on one set of railway lines at regulated intervals. Regulated intervals refer to the predetermined schedules or timings that are strictly followed to manage and coordinate the movement of trains on the same track to avoid collisions and ensure smooth transit. This system necessitates precise timing and the use of signals or communication systems to control train movements, as there may not be an alternative track available for the opposite direction or for another train to pass simultaneously.
The rise of the railroads, including the complexities of managing single tracks with regulated intervals, underscored the importance of fixed schedules and precise timing, a change that was fundamental in how time was measured and communicated, especially after the synchronization of time was instituted on November 18, 1883, to aid in the coordination of train schedules. This transformation was not only crucial for the safety and efficiency of the railways but also played a vital role in the broader societal adaptation to standardized time. India's vast and historically rich railway system is the fifth largest in the world, demonstrating the country's substantial progress and its impact on connecting various regions, carrying millions of passengers, and fostering economic activity.

4. Which scientist developed the theory of gravitation and used it to explain the orbits of celestial bodies?
A. Johannes Kepler
B. Galileo Galilae
C. Isaac Newton
D. Copernicus
The answer is c. Isaac Newton was the one who discovered gravity and explained it.
Isaac Newton developed the theory of gravitation and explained the orbits of celestial bodies.
Explanation:
Newton's law explains about the “strength of the gravitational force between two objects” that drops off when light gets dimmer by moving away from it. It is mathematically known as an “inverse square law”.
The next method to visualise the drop-off in the field is to imagine the gravitational field around an object in series of concentric spheres. The same amount of gravitational field is represented by each sphere, but the spheres farther from the object are bigger, so that same amount of field is spread thinner, over a larger area.
How is the conflict between Hally and Sam symbolic of a larger conflict between white and black South Africans? In
about two hundred words, describe what implied theme their conflict represents.
Answer:
The title of this story Master Harold and the boys is symbolic. The title suggests a hierarchy. This play has been written in the South African context. The setting of the story has been South Africa. Master Harold, a seventeen year old boy, is a white. But the boys who are matures men of the forties are black and have been working in the restaurant of Hally. The boys, though grownups are called boys only on the ground of their dark complexion. But it is strange to hear a seventeen year old boy as Master Harold. The names of the boys are, respectively, Sam and Willie. They are waiters in the restaurant. The title symbolizes the racial discrimination of South Africa. South Africa was the country where the apartheid law was creating two states within a nation, state of blacks and state of whites in a nation. Racism was creating a boundary between two states. The play examines the effects of apartheid system, it is about love and hate relationship.
Explanation:
Answer:
I will be talking about how the conflict between the characters Hally and Sam is symbolic of a larger conflict between the white people and the black South Africans and I will also be describing what implied theme that their conflict represents. Since Hally is a white boy and he is the son of the owner he is master harold, and Sam and Willie are just the servants that work there. Sam and Hally have a friendship type of bond with each other even though back in the 1950s it was not at all allowed for black and white people friends because of the apartheid. Apartheid was a system of racial segregation based on skin colour common in South Africa. I think that the reason why the conflict between Hally and Sam is symbolic of a larger conflict between white and black South Africans is because of the apartheid and racial discrimination in South Africa. When you think about the title of the book "Master Harold.....and the boys" is says that Harold who is Hally is the white master of the servants Sam and Willie who are the boys which I think is related to the racial discrimination in the book. I think that the theme that is implied with their conflict represents racial discrimination.
Explanation:
How is the water in a lake different from the water in a stream? What's the difference between a closed lake and an open lake? Explain why lakes are considered temporary bodies of water. What's the main difference between a marsh and a swamp? Identify four functions that wetlands perform.
1. The main difference between the water in the lakes and the water in the streams is that the water of the lakes is enclosed, thus it is more static (relatively speaking), while the water from the streams is moving along the banks. The water of the lakes is relatively static. Not to get me wrong, it moves, but it moves in an enclosed area, and it moves horizontally, not downward. The water of the streams on the other hand is moving much quicker, and it moves along the banks. This water moves downward, from the higher parts toward the lower parts.
2. The difference between a closed lake and an open lake is that the close lake doesn't have water from another body of water coming in and going out of it, while the open lake has exactly that. The close lakes don't have rivers and streams coming into them, nor there's a river or stream coming out of them, they are closed by higher physical features. The open lakes on the other hand have rivers and streams coming into them, as well as having an opening from the which the water is coming out, thus there's a stream or river coming out of it, which makes the water slowly circulate and change.
3. The lakes are not the most reliant bodies of water when it comes to being long lasting. The reason for that is that they are bodies of water that are the easiest affected by the changes in the climate, as well as the changes in the relief. The geological activities can simply make the lake go up, or lean sideways, thus it can lose its water through runoff. If the rainfall decreases, then the lake will have higher loss of water through evaporation then what it gets, resulting in drying out.
4. The main difference between the marshes and the swamps is that the marshes are wetlands that are very rich in nutrients and they support grasses and reeds, while the swamps are wetlands that can support trees and other woody plants. The marshes can be found on the fringes of the lakes and the rivers, and they re practically a transitional zone between the waters of these water bodies and the land. The swamps are found along the shores of the lakes and the large rivers.
5. The wetlands have numerous functions in the natural order, some of which are:
- flood storage
The waters of the wetlands manage to slow down and store big portion of any incoming water, thus being able to either stop a flood, or at least minimize its effects
- protecting the water quality
The wetlands, with the amount of water they have, as well as all the different types of bacteria in them, manage to filter out the waters that polluted and coming into them, thus serving as a nice natural filter.
- prevention of erosion
Because the wetlands manage to slow down the waters, they contribute significantly to minimizing the downstream erosion, thus keeping the soil in healthier condition
- providing habitat for lot of plants and animals
The wetlands offer nice living conditions for lot of plants and animals. They provide lot of water, often rich in nutrients, shelter, hunting ground, food sources, enabling for numerous different types of ecosystems to develop in them.
1. The water in a lake tends to be calmer and less turbulent compared to the fast-flowing water in a stream. Lakes often provide a more stable environment for aquatic organisms due to their stillness.
2. A closed lake has no natural outlet, causing water to accumulate within its basin and potentially leading to higher mineral concentrations. In contrast, an open lake has an outlet that allows water to flow out, maintaining a more balanced water composition.
3. Lakes are considered temporary because they are subject to natural processes such as evaporation, sedimentation, and changes in precipitation. These factors can cause lakes to shrink, dry up, or even merge with other water bodies over time.
4. Marshes are characterized by herbaceous plants like grasses and reeds, while swamps are dominated by trees and shrubs. This distinction in vegetation type is the main difference between the two wetland types.
5. Wetlands, including marshes and swamps, perform crucial functions in the ecosystem. They act as natural water filters, removing pollutants and improving water quality. Wetlands also serve as natural buffers against floods, provide habitat for diverse species, and play a significant role in carbon sequestration, helping mitigate climate change.

Hello!
The other name of drainage basins are even called water sheds
Thanks for using Brainly!
Another name for a drainage basin is watershed or even a catchment basin/area
Explanation:
It is a piece of land where water collects and later drains off into the same outlet. This water gets collected from rain, snowfall, underground water and nearby narrow streams. They form a hierarchical pattern by connecting with other basins.
The drainage divide is what divides basins from one another by forming topographical barriers. Close basin is one type where there is a single point known as the sink within the basin where all the water collects. This sink could a lake which is dry or an area where all water on surface is lost underground.

how do plants help in erosion control?
Answer:
provide protective cover on the land and prevent soil erosion for the following reasons: Plants slow down water as it flows over the land and this allows much of the rain to soak into the groun
Explanation:
Answer: Plant roots help to hold the soil in place. Plants often bind the soil together with their root systems, which means they're able to serve as a protective layer that can help prevent soil erosion in several ways. For example, the soil is also protected from direct rainfall, as plants help break in the impact of raindrops before they hit the ground.
To test the hypothesis that plants grow faster in green light, a student set up 3 of the same type of plants. She placed the first plant under a green light, the second plant under a regular light bulb, and the third plant under a red light.
What is the independent variable in this experiment?
A.
pot size
B.
light color
C.
plant type
D.
amount of water
Final answer:
The independent variable in the plant growth experiment is light color. Light color is the variable being changed to test its effect on plant growth with blue light likely promoting the most growth, followed by red, and then green, due to the absorption properties of chlorophyll.
Explanation:
The independent variable in this experiment is B. light color. This is the variable that the student is intentionally changing across the three plants to test its effect on plant growth. The other options, such as pot size, plant type, and amount of water are kept constant to ensure that they do not affect the outcome of the experiment and can be considered as controlled variables.
Considering the effects of different light colors on plant growth, particularly concerning chlorophyll a and chlorophyll b, which are the two main types of chlorophyll used in photosynthesis, the predicted order of the plants from most growth to least growth would be: blue light, red light, and finally green light. This is because chlorophyll absorbs light most efficiently in the blue and red regions of the spectrum and least efficiently in the green region.
What was so revolutionary about the Neolithic Revolution? Speculate on why it was named this.
M
Answer:
The revolutionary aspect of the neolithic period is the fact that people started agriculture.
Explanation:
The neolithic period is also referred to as the Agricultural Revolution.
During this period, people moved from practicing hunting and gathering in small bands to larger civilized agricultural settings.
The neolithic age was characterized by people using stone tools for the purpose of hunting and gathering, so the neolithic revolution was basically a revolution from primitive stone tools to more mechanised farming.
Answer:
Introducing the concept of agriculture
Explanation:
The Neolithic period refers to the final stage of the stone age, which was during the time of Holocene Epoch, about 11,700 years back. It was during this time, where there occurred significant changes such as the agricultural concept was introduced. They were able to grow agricultural crops and lived in small groups, forming a small type of village. They made more advanced stone tools that helped them for hunting purposes.
This was so revolutionary about the Neolithic Revolution as they started to evolve and became more advanced.
Absolute-age dating techniques can be used to determine the age of which of these? Select all that apply.
A. Earth
B. some rocks
C. some fossils
D. substances made entirely of Pb-206
E. substances made entirely of Ar-40
The answer is B and C
the correct answer is option a, b and c. Absolute-age dating techniques can determine the age of Earth, some rocks, and some fossils using isotopes such as uranium-238 and potassium-40. However, substances made entirely of Pb-206 or Ar-40 are not suitable for these methods. Examples include uranium-lead and potassium-argon dating techniques.
Absolute-age dating techniques can be used to determine the age of certain materials based on the radioactive decay of isotopes. Here are the appropriate applications:
A. Earth: Scientists can estimate Earth's age by dating the oldest rocks and minerals using methods such as uranium-lead dating.B. Some rocks: Various dating techniques like uranium-238 to lead-206 and potassium-40 to argon-40 are used to date rocks.C. Some fossils: Fossils can be dated using methods like uranium-lead dating, though not all fossils will contain suitable isotopes for this purpose.Items D and E are not directly relevant for dating using these techniques because substances made entirely of Pb-206 or Ar-40 do not provide a decay process that can be measure; Using uranium-238, which decays to lead-206, geologists can date rocks and estimate Earth's age. Likewise, potassium-40 decaying to argon-40 is a reliable method to date ancient rocks.

When one area of the world is economically affected by a natural disaster in another country, what is this called?
Economic interconnectedness means that a natural disaster in one country can lead to environmental disturbances that affect the global economy, altering supply and demand and impacting economies worldwide.
Explanation:When one area of the world is economically affected by a natural disaster in another country, this phenomenon is often referred to in social studies as an environmental disturbance or more broadly as the interconnectedness of the global economy. For instance, economies focused on farming and fishing may experience direct impacts from an environmental event like El Niño, leading to issues like crop failures or reduced yield in fisheries. However, such events can have a cascading effect on global markets, affecting supply and demand worldwide, influencing prices and availability of goods and services far beyond the point of origin. Indeed, the merging of regional economies has meant that nations are increasingly dependent on one another, making any environmental disturbance a matter that can impact economies on a global scale.
Final answer:
Natural disasters causing economic impacts in other regions are known as cascading consequences.
Explanation:
When one area of the world is economically affected by a natural disaster in another country, it is called cascading consequences. These consequences can impact people, organizations, and the economy through various means such as unemployment, business failures, disruptions of the food supply chain, and rising social problems in struggling communities. When one area of the world is economically affected by a natural disaster in another country, this phenomenon is often referred to as cascading consequences. These consequences can be both direct, such as destroyed infrastructure and loss of life, and indirect like financial losses, unemployment, and disruptions in the supply chain. An illustrative example is the impact of natural disasters on economically vulnerable states, where tangible assets and human capital can be destroyed, reducing production capacity and destabilizing economies that were not directly hit by the disasters.
The biggest objection to Wegener's continental drift hypothesis was _____.
a) there was no evidence to support it
b) the fossil record didn't match
c) the "fit" between Africa and South America
d) it didn't explain how the continents moved
Answer:
a) there was no evidence to support it
Explanation:
Wegener noticed while looking at the maps that some parts of the continents, especially South America and Africa, seem to match up perfectly. This led him to think that maybe the continents in the past were actually connected, but because of some force they moved apart. He went out public with his hypothesis, but it was largely rejected, and he was laughed at and ridiculed, as the scientists thought that there's no force that can move the continents. Wegener didn't stop there, and he continued to look for clues, and finally managed to find some clues at the topography of the Atlantic Ocean. He noticed that the mid-ocean ridge is the highest, but as you move away from it, the sea mounds are becoming flatter and lower, thus a sign of erosion, and he actually turned out to be right.

Which principle tells you how rock layers are laid
The Principle of Original Horizontality states that rocks are laid down horizontally, while the Principle of Superposition is often used to determine the relative ages of rock layers, with the oldest at the bottom. The option (C) is correct.
The principle of Original Horizontality states that layers of rocks deposited from above, such as sediments and lava flows, are originally laid down horizontally. However, when analyzing the relative ages of rock layers, the Principle of Superposition is most often used.
This principle states that in an undisturbed sequence of sedimentary strata, or rock layers, the layers at the bottom are the oldest, and the layers above them are younger. Therefore, when determining the age of rock layers without any other context, the Principle of Superposition guides us in understanding that older layers are located below younger layers.
This question is not complete, Here I am attaching the complete question:
Which principle tells you how rock layers are laid?
A) Principle of Stratification
