Atmosphere
a atmosphere is the layers of gases surrounding a planet
Altitude
is the height above sea level of a location
Density
a mass of a unit volume of a material substance
Troposphere
the troposphere is the lowest layer of Earth’s atmosphere
Stratosphere
a layer of Earth’s atmosphere
Mesosphere
The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases.
Thermosphere
The thermosphere is the layer in the Earth’s atmosphere directly above the mesosphere and below the exosphere.
Mesosphere
a layer of Earth’s atmosphere
Exosphere
the outermost region of a planet’s atmosphere.
Temperature
degree of hotness or coldness measured on a definite scale.
Thermosphere
a layer of Earth’s atmosphere that is directly above the mesosphere and below the exosphere
Nitrogen
the chemical element of atomic number 7, a colorless, odorless unreactive gas that forms about 78 percent of the earth’s atmosphere.
Carbon Dioxide
A colorless, odorless gas that is present in the atmosphere and is formed when any fuel containing carbon is burned.
Exosphere
the outermost layer of our atmosphere
Oxygen
a colorless, odorless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air.
Temperature
degree of hotness or coldness measured on a definite scale

The force exerted on a surface by the air above it as gravity pulls it to Earth.
concentration
concentration is the abundance of a constituent divided by the total volume of a mixture.
Nitrogen
nonmetallic element of Group 15 [Va] of the periodic table
condition
