The Earth's atmosphere is divided into five main layers: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.

These layers are distinguished primarily by their temperature profiles and altitudes

Troposphere is the lowest layer, where weather occurs and where most life exists

The troposphere extends from the Earth's surface up to about 12 km (7 miles)

Above the troposphere lies the stratosphere, which contains the ozone layer that absorbs harmful ultraviolet radiation from the sun

The Mesosphere is the layer where meteors burn up, and it extends from about 50 km to 80 km (31-50 miles)

The thermosphere is characterised by high temperatures and the presence of the ionosphere, which can reflect radio waves

The Exosphere is the outermost layer, where the atmosphere gradually fades into space
