The surrounding air of the Earth Atmosphere The surrounding air of the Earth

Layers of the atmosphere There are 4 layers in the atmosphere They are the troposphere, mesosphere, thermosphere, and stratosphere

Troposphere This is the layer that is closest to the surface of the earth It’s elevation ranges from 0 to 10 km

Stratosphere This layer sits on top of the troposphere It’s elevation ranges from 10 km to around 25 km This layer contains the ozone layer, which protects us from harmful sunlight

Mesosphere This layer is above the stratosphere It’s elevation ranges from 25 to 100 km

Thermosphere This is the highest layer of the atmosphere It’s height ranges from 100 to 400 km This is where most small meteorites burn up and is also the location in the atmosphere that the northern lights occur (aurora borealis)

Composition of Air There are many different types of gasses in the atmosphere They include nitrogen, oxygen, argon, carbon dioxide and other noble gasses The gas that is most abundant is nitrogen
