4. The lowest layer of Earth’s Atmosphere…. The TROPOSPHERE
-The Troposphere is the lowest layer of the atmosphere, and
makes up about 75-80% of Earth’s atmosphere.
- The Troposphere is where all of Earth’s weather occurs.
- The higher you go up the Troposphere, the colder it gets.
The air also gets thinner as you travel upward of the
Troposphere. are at
