The gas that is the largest component of the atmosphere is oxygen. The correct option is B. In nature, nitrogen (N2), which accounts for about 78% of air, is the most prevalent gas. The second most prevalent gas after nitrogen (N2) is oxygen (O2).
Which gases are most important?One of the most crucial gases to humans is oxygen. Due to the necessity of carbon dioxide for photosynthesis in plants, it is one of the most vital gases for all life on Earth.
The other main factor is that, in contrast to oxygen, nitrogen is much more stable in the atmosphere and plays a much smaller role in chemical reactions that take place there. As a result, it has accumulated in the atmosphere to a much greater extent than oxygen over geological time.
Thus, the ideal selection is option B.

In addition to the two thousand languages, there are another eight thousand dialects. Thus, multilingualism is the main characteristic of the continent. The presence of innumerable variants sharing the same living spaces end up providing unique and complex ways of seeing and interpreting the world.

The hot spring deposits at mammoth hot springs, yellowstone national park, are travertine. what rock probably lies somewhere beneath the hot springs?
Travertine deposits at Mammoth Hot Springs are formed from the precipitation of calcium carbonate from mineral-rich water, indicating a likelihood of limestone being present beneath. This limestone formation process is common in hot spring environments.
The rock that probably lies beneath the travertine deposits at Mammoth Hot Springs in Yellowstone National Park is limestone.
This is because travertine is a type of limestone that forms from the precipitation of calcium carbonate from mineral-rich water, commonly seen in hot spring environments.
Limestone is a sedimentary rock made primarily of calcium carbonate, matching the process that results in travertine formation.

The length of time that a volcanic eruption impacts the climate is largely determined by
Answer:
The length of time that a volcanic eruption impacts the climate is largely determined by whether the ash or gas reaches the stratosphere
Explanation:
A volcanic eruption releases gases and other particles in the atmosphere. The factor whether these released material reaches the stratosphere or not, determines whether that particular volcanic eruption will affect the climate or not.
The enormous output from the eruption gets released in the atmosphere. This output forms a permanent layer in the atmosphere over time and becomes a barrier to the sunlight reaching the earth.
The decrease in sunlight causes cooling effect thereby decreasing the temperature of the planet.
The time taken by the emission to reach the stratosphere determines the time taken by the emission to change the climate of the planet.

What forms when a river enters a large body of water?
Bedrock and sediment in a stream is most susceptible to erosion if it is:
ANSWER:
Bedrock and sediment is most susceptible to erosion if it is located in the turbulent part of the stream or the river.
EXPLANATION:
The turbulent part of the river is the one where the water velocity is high. This high water velocity carries away bedrock and sediment easily. The edge where the bedrock and sediment is located tends to be very steep. This steepness makes it easy for the high velocity of water to carry away the bedrock and sediment. This bedrock and sediment is also carried to greater distances because of the great speed of water.In three activities, how can I change my daily habits to help the ecosystem?
Hot water from the tap often requires running cold water until we can get hot water. In most cases instead of preserving the cold water in the container to use later, we let it run down the drain and get wasted. This happens in kitchen sinks, bathroom sinks and showers. On a daily basis, a lot of liters of water is wasted this way.
2. Opt for reusable plastic bags :Bags end up in landfills or causing litter in the environment. The danger of plastic bags is that most of them don't decompose. Animals and birds digest this material and die. Another environmental hazard from plastic bags is increased pollution in rivers, streams and oceans. Therefore, a reusable plastic bag reduces the frequency of buying and disposing, protecting the environment.
3. Do not litter :Packages whether it is food packaging or packages for other products have a “don't litter” or “throw in a rubbish bin” message and recycling sign. Regardless of that, there is rubbish all over. Avoid littering and using save and recommended manner of disposing of garbage is very important.
