Atmosphere

A blanket of glasses that protects Earth and regulates temperature. It also lets us breathe

Air pressure

Air pressure is air molecules pressing down on Earth.

Altitude

The distance above sea level

Barometer

A tool used to measure air pressure

Troposphere

Is the lowest layer. All life and weather occur here. And in addition is also the most dense layer

Stratosphere

The second layer of the atmosphere has no clouds, but it does have wind. The stratosphere has the ozone layer which protects us from harmful UV rays and let's in the good UV rays. Some forms of bacteria live here

Mesosphere

The third layer of the atmosphere and the coldest layer too. Meteors burn up in this layer due to friction of particles and molecules. Also the lower you are the colder it is and the higher it is the warmer it is

Thermosphere

The fourth layer and the hottest layer. It is the biggest layer and you can’t feel the heat because the molecules are so far apart. In addition to that the Karman line is here

Exosphere

The Exosphere is the outer space layer of the atmosphere and it is 400 miles high to about 800 miles high
