THE EARTH'S 5 ATMOSPHERE LAYERS.
BY Phillip Richardson,jr.
the earth's atmosphere has five layers in it. Troposphere, thermosphere, exosphere, mesosphere , stratosphere are the five layers that protect us from getting hit with a meteor. so lets think about what they do and mean.
let us start out with troposphere. That is the lowest layer in the atmosphere.It starts at the earth's surface and goes up to a height of 7 to 20 km.
now lets start out with stratosphere. It is the second layer in the atmosphere.The top of the stratosphere occurs 50 km altitude and the boundary between stratosphere and mesosphere is stratopause.
The next one we are going to do is mesosphere. It is above the ......
- stratosphere.The mesosphere starts at 50 km above earth's surface and goes up to 85 km high.
now we are going to do thermosphere .It is directly above the mesosphere layer,and below the exosphere. It extends about 90 km to between 500,to 1,000 km. The boundary between this one and mesosphere is called mesopause.
The exosphere is the highest and it becomes very thin. The region where atoms and molecules escape into space is referred to as the exosphere.
