BUT IT SHOULD BE NOTED that this is the composition of DRY air. Water vapor can theoretically take up anywhere from almost 0 to nearly 7 percent of air volume (but it's never been measured that high). All other components are reduced proportionally.
What else can I help you with?
Does the density of the earths atmosphere increase with altitude or decrease?
The density of Earth's atmosphere decreases with altitude. As you move higher up in the atmosphere, there are fewer molecules of gases present, leading to lower density.
How does the composition gases changes as you travel in earths atmosphere?
As you travel higher in Earth's atmosphere, the composition of gases changes in terms of their concentration. Oxygen, nitrogen, and argon are the most abundant gases in the lower atmosphere, while the percentage of oxygen decreases and other gases like helium and hydrogen become more prevalent in the upper atmosphere. The overall pressure also decreases with altitude, causing the air to become less dense.
What extends from inside earths crust to the lower atmosphere?
Biosphere
What heats earths atmosphere?
The sun heats the atmosphere. Solar radiation largely passes through the atmosphere and warms the surface of the earth. The earth then radiates heat up into the lower levels of the atmosphere where greenhouse gases warm. The warmed greenhouse gases then continue to radiate heat in all directions warming the atmosphere and again the earth's surface.
What is the gradual increase of the average air temperature in the earths lower atmosphere called?
The gradual increase of the average air temperature in the Earth's lower atmosphere is called global warming. This phenomenon is mainly caused by human activities that release greenhouse gases into the atmosphere, leading to the trapping of heat and an overall rise in temperatures.

What are the lower gases in the atmosphere?
Nitrogen and Oxygen

How does solar radiation leave earths atmosphere?
Solar radiation leaves Earth's atmosphere through a process called reflection and absorption. Some of the radiation is reflected back into space by clouds, gases, and particles in the atmosphere. The remaining radiation is absorbed by the surface of the Earth, where it is converted into heat energy.

Where is most of the water vapor and carbon dioxide in earths atmosphere found?
Upper Part

How would earths average temperature be different if there were no greenhouse gases in the atmosphere at all.?
If there were no greenhouse gases in the atmosphere, Earth's average temperature would be significantly colder. Greenhouse gases like carbon dioxide and methane trap heat in the atmosphere, helping to keep the planet warm. Without them, Earth's surface would not retain as much heat from the sun, resulting in much lower temperatures.
What are the main gases in earth lower atmosphere?
Nitrogen and Oxygen
What is the approximate percent of oxygen by volume present earths lower atmosphere?
Oxygen makes up about 21% of Earth's lower atmosphere by volume.
What would earths atmosphere be like if life had not evolved?
Without life, Earth's atmosphere would lack oxygen, as it is primarily produced by photosynthetic organisms. The composition of gases would likely be primarily nitrogen and carbon dioxide, similar to the early Earth's atmosphere. There would also be fewer greenhouse gases, leading to lower temperatures on the planet.
