How many layers does earth's atmosphere have?

Answer 1

I think there are 5 layers in our atmosphere; It is thickest near the surface and thins out with height until it eventually merges with space.

1. The troposphere is the first layer above the surface and contains half of the Earth's atmosphere. Weather occurs in this layer.
2. Many jet air crafts fly in the stratosphere because it is very stable. Also, the ozone layer absorbs harmful rays from the Sun.
3. Meteors or rock fragments burn up in the mesosphere.
4. The thermosphere is a layer with auroras. It is also where the space shuttle orbits.
5. The atmosphere merges into space in the extremely thin exosphere. This is the upper limit of our atmosphere.
6. If you wanna know more, then see the related links.

There are 4 main layers, however 1 of them is divided in half.

Troposphere

Stratosphere

Mesosphere

Thermosphere (top half is: Exosphere)

(bottom half is: Lonosphere)
