Answer 2

Answer:

The atmosphere is the blanket of gases that surrounds Earth. It is held near the surface of the planet by Earth's gravitational attraction. Without the atmosphere, there could be no life on Earth.

The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere, and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere.

There are four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). Each of these four spheres can be further divided into sub-spheres.
