Explanation:

Detailed explanation-1: -Approximately, the Earth’s atmosphere extends upto 1, 600 km above the surface of the Earth.

Detailed explanation-2: -Mesosphere. This layer extends from around 31 miles (50 km) above the Earth’s surface to 53 miles (85 km).

Detailed explanation-3: -The air is really a mixture of many different gases, and each gas has its own properties. The composition of air is not constant. It can vary from time to time and place to place.

Detailed explanation-4: -Thermosphere. Between about 53 miles (85 km) and 375 miles (600 km) lies the thermosphere, known as the upper atmosphere. While still extremely thin, the gases of the thermosphere become increasingly denser as one descends toward the Earth.
