Here is a list of the different types of atmospheres in our sky.

Troposphere (lowest level):

  • The troposphere is the lowest layer of Earth’s atmosphere.
  • Most of the mass (about 75-80%) of the atmosphere is in the troposphere.
  • Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.
  • The bottom of the troposphere is at Earth’s surface.

Stratosphere (2nd layer):

  • The stratosphere is a layer of Earth’s atmosphere.
  • It is the second layer of the atmosphere as you go upward.
  • The troposphere, the lowest layer, is right below the stratosphere. … The lower boundary of the stratosphere is called the tropopause; the upper boundary is called the stratopause.

Mesosphere (3rd layer):

  • The mesosphere is a layer of Earth’s atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet.
  • Temperature decreases with height throughout the mesosphere. The coldest temperatures in Earth’s atmosphere, about -90° C (-130° F), are found near the top of this layer.

Thermosphere (4th layer):

  • The thermosphere is a layer of Earth’s atmosphere that is directly above the mesosphere and below the exosphere.
  • It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above our planet.

Exosphere (uppermost layer):

  • The exosphere is the uppermost region of Earth’s atmosphere as it gradually fades into the vacuum of space.
  • The air in the exosphere is extremely thin – in many ways it is almost the same as the airless void of outer space.
