Makes up approximately 75% of the total mass of the atmosphere and 99% of the atmosphere's water vapor, contains wind, clouds, and water
Stratosphere
The temperature in this layer increases with altitude, contains the ozone layer
Mesosphere
The temperature in this layer decreases with altitude, the coldest layer of the atmosphere surrounding the Earth
Thermosphere
Comparatively closer to the sun and absorbs a large amount of solar radiation, the temperature in this layer increases tremendously as the distance from the Earth becomes greater
Ionosphere
Aurora borealis (north) and aurora australis (south) occur in this layer
Exosphere
The temperature in this region varies from very hot to very cold, artificial satellites orbit in this layer
The earth's atmosphere is divided into different layers and is made of different types of gases
More than three quarters of earth's atmosphere is made up of nitrogen while one film is oxygen
The remaining one percent is a mixture of carbon dioxide water vapor ozone and other trace gases
