Slide 1

Atmosphere

The surrounding air of the Earth

Slide 2

Layers of the atmosphere

There are 4 layers in the atmosphere

They are the troposphere, mesosphere, thermosphere, and stratosphere

Slide 3

Troposphere

This is the layer that is closest to the surface of the earth

It’s elevation ranges from 0 to 10 km

Slide 4

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

Slide 5

Mesosphere

This layer is above the stratosphere

It’s elevation ranges from 25 to 100 km

Slide 6

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)

Slide 7

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
