The exosphere, the outermost layer of Earth's atmosphere, primarily consists of hydrogen and helium, along with trace amounts of other gases like carbon dioxide, oxygen, and neon. Due to its extremely thin atmosphere, particles in the exosphere are so sparse that they can travel long distances without colliding with one another. This layer extends from approximately 600 kilometers (about 370 miles) above the Earth's surface to around 10,000 kilometers (about 6,200 miles).

In what layer are light gases such as helium and hydrogen found?

Light gases such as helium and hydrogen are found in the exosphere layer of the Earth's atmosphere. The exosphere is the outermost layer and consists of very low-density gases that extend out into space.

What is the top layer of earths atmosphere called?

The top layer of Earth's atmosphere is called the exosphere. It is the outermost layer where the atmosphere transitions into space. The exosphere is very thin and composed mostly of low-density gases.


What layer of the atmosphere contains the fewest gases?

The thermosphere is the layer of the atmosphere that contains the fewest gases. Although it is a very low-density layer, it is composed mainly of nitrogen and oxygen atoms.


Which atmospheric layer contains the fewest gases?

The exosphere is the atmospheric layer that contains the fewest gases. It is the outermost layer of Earth's atmosphere and consists of very low densities of hydrogen and helium, along with traces of other gases.

What is the density of the exosphere?

The exosphere is the upper layer of the atmosphere. The exosphere has a very low density, due to the lighter gases that are present in the exosphere. Hydrogen, with some helium, carbon dioxide, and atomic oxygen is found near the exobase. he exosphere is the last layer before outer space.

What layer of the atmosphere is about 550 km to 1000 km?

The layer of the atmosphere that is approximately 550 km to 1000 km above Earth's surface is the exosphere. This region is the outermost layer of the atmosphere where the gases are very thin and the few particles present can escape into space. The exosphere is where the atmosphere merges with outer space.


What does the exosphere do for earth?

Nothing. It has been recorded that gases are kept in a layer before trailing off into space, and this area was dubbed the exosphere. Some satellites orbit here.


Which layer of the atmosphere contains the least concentration of the Earth's gases?

The exosphere, the outermost layer of Earth's atmosphere, contains the least concentration of gases. It is where the atmosphere transitions into outer space, with the density of gases extremely low and gradually dissipating into the vacuum of space.
