Answer:

     The atmosphere is the layer of gas that surrounds Earth. It is often called air. Other planets, and some of their larger moons, also have atmospheres.

     The atmosphere consists of several different gases. The gases are held close to Earth by a force called gravity. Near Earth’s surface, the atmosphere is about three-fourths nitrogen and one-fifth oxygen. At higher elevations, the atmosphere is mostly hydrogen and helium.

Answer 2

The atmosphere is the gaseous layer that envelops the Earth. It's commonly referred to as air. There are atmospheres on other planets, as well as some of their bigger moons.

The atmosphere is made up of a variety of gases. Gravity keeps the gases close to the surface of the Earth. The atmosphere at the Earth's surface is around three-quarters nitrogen and one-fifth oxygen. The atmosphere contains primarily hydrogen and helium at greater heights.

From the farthest to the closest layer of the atmosphere

1. the exosphere

2.  thermosphere

3. stratosphere

4.stratosphere
