Question

Earth's atmosphere is classified primarily based upon altitude above sea level

Answer 1

Troposphere.

Explanation:

Earth's atmosphere is unique when it comes to its properties and no other planet or moon has been observed to have the same or similar atmosphere. The atmosphere is one of Earth's spheres and it it is representing the sphere that is located between the surface of Earth and space, being comprised of gasses and small particles.

The atmosphere is divided into several layers:

• troposphere
• stratosphere
• mesosphere
• thermosphere
• exosphere

The one situated at the bottom is the troposphere. It is located between 0 and 10 km in elevation. This part of the atmosphere is the densest and richest in gasses and particles. It is where all of the weather on Earth occurs, and it is the layer that contacts with the other spheres the most and is crucial for the life on our planet.
