Presentation transcript:

Atmosphere The surrounding air of the Earth

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

Troposphere This is the layer that is closest to the surface of the earth This is where most of our weather occurs It’s elevation ranges from 0 to 12 km above sea level.

Stratosphere This layer sits on top of the troposphere It’s elevation ranges from 12km to around 50 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 50 to 80 km Most meteroids burn up here.

Thermosphere This is the highest layer of the atmosphere It’s altitude starts above 80 km. This is where space shuttles go. It is split into two parts: the ionosphere and the exosphere.

Ionosphere The ionosphere falls between 80 and 400 km. Ions break down here, reflecting radio waves back down to Earth – causing the Aurora Borealis.

Exosphere Above 400 km Atmosphere is extremely thin Satellites for phones and television pictures orbit here.
