Earth’s atmosphere has six different layers ____ the troposphere, stratosphere, mesosphere, thermosphere, ionosphere, and exosphere. They go from the ground all the way to outer space.
|

|
The mesosphere is 22 miles (35 kilometers) thick. The mesosphere starts just above the stratosphere and extends to 53 miles 85 kilometers) from the Earth’s surface. The air is still thin, so you wouldn’t be able to breathe up in the mesosphere.

When you feel the wind on your face, see clouds in the sky, and watch a bird flap its wings in flight, you’re experiencing the troposphere. It’s a pretty nice layer to call home.

Its a very active part of the atmosphere, and it grows and shrinks depending on the energy (radiation) it absorbs from the sun. Its name comes from the fact that gases in these layers are excited by solar radiation to form “ions, “ which have an electrical charge.

Detailed explanation-1: -Atmosphere is the thin layer of air that surrounds the earth. It is made up of various gases such as oxygen, nitrogen, carbon dioxides, dust particles and water vapour. The gravitational force of the earth holds the atmosphere around it. It protects us from harmful rays and scorching heat of the sun.
Detailed explanation-2: -The different layers of the atmosphere. The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth’s surface, is called the exosphere.
Detailed explanation-3: -Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.
