| troposphere | The troposphere is the lowest portion of Earth's atmosphere. It contains approximately 80% of the atmosphere's mass and 99% of its water vapour and aerosols. The average depth of the troposphere is approximately 17 km in the middle latitudes.

| stratosphere | the layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface
🗑

| mesosphere | The mesosphere is the layer of the Earth's atmosphere that is directly above the stratopause and directly below the mesopause. In the mesosphere temperature decreases with increasing height

| ionosphere | he ionosphere is a region of the upper atmosphere, from about 85 km to 600 km altitude, and includes the thermosphere and parts of the mesosphere and exosphere. It is distinguished because it is ionized by solar radiation.
