In the Earth’s atmosphere there are not only gases, but solids and liquids.
All weather occurs in the troposphere.
Wind is the movement of air from an area of higher pressure to an area of lower pressure.
Narrow belts of strong wind near the top of the troposphere are called jet streams.
A thin layer of air that forms a protective covering around the planet is called the atmosphere.
As you go higher in the troposphere, the temperature increases.
