GEOLOGY

Detailed explanation-1: -Exosphere. This is the outermost layer of the atmosphere. It extends from the top of the thermosphere to 6, 200 miles (10, 000 km ) above the earth. In this layer, atoms and molecules escape into space and satellites orbit the earth.

Detailed explanation-2: -The crust is the outermost layer of Earth.

Detailed explanation-3: -Stratosphere. The next layer up is called the stratosphere. The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. The infamous ozone layer is found within the stratosphere.

Detailed explanation-4: -The air in the exosphere is extremely thin-in many ways it is almost the same as the airless void of outer space. The layer directly below the exosphere is the thermosphere; the boundary between the two is called the thermopause. The bottom of the exosphere is sometimes also referred to as the exobase.

Detailed explanation-5: -Mesosphere, coldest layer of Earth’s atmosphere.
