The gravity of a body - planet or other material - holds a layer of gases.
See the layers:
Mesosphere - Stratosphere - Troposphere
Air envelops the Earth and makes life possible.|
Humans breathe in about 35 pounds of air everyday!
Many air molecules build up air pressure - Air around our Earth is called atmosphere.|
The air-layer closest to the earth is the troposphere where invisible chemical cycling of essential elements takes place, as well as the uneven heating of Earth's surfaces that creates our weather.
The air of the troposphere is made up of gases with several other natural ingredients.
Some of air's gases remain fairly constant.
Nitrogen, oxygen and argon make up the chief of these gases at approximately 78, 21, and 1 percent by volume.
Small amounts of water vapor, carbon dioxide, methane, nitrogen dioxide and sulfur dioxide are also part of our air.
All of these bits of matter play an important role in our weather by providing surfaces for condensation and eventually, precipitation, allowing water that evaporates from the ocean and land to rejoin us on the Earth's surface. Additionally, rain and other forms of precipitation wash some of these particles down to the Earth's surface.
