The Layer Of Earth's Atmosphere

Da'Miya S. L. Spencer

Here on this awesome TACKK. I will have things about EARTH'S ATMOSPHERE.

I will be making a TACKK that will talk about the Earth's Atmosphere.

Exosphere

First's up is the exosphere. Which the exosphere is the outermost region of a planet's atmosphere.The exosphere is almost a vacuum. The "air" is very, very thin there. When air is thin, it doesn't transfer much heat to objects in the air, even if the air is very, very hot.

Thermosphere

Now it's the thermosphere turn's. The thermosphere is the biggest of all the layers of the earth's atmosphere directly above the mesosphere and below the Within this layer, ultraviolet radiation causes ionization. The International space Station has a stable orbit within the middle of the thermosphere, between 320 and 380 kilometres. Auroras also occur in the thermosphere.The highly diluted gas in this layer can reach 2,500 °C (4,530 °F) during the day.

Mesosphere

Now after the thermosphere is now the mesosphere. What the mesosphere is, is the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles in altitude. The mesopause is the temperature minimum at the boundary between the mesosphere and the thermosphere atmospheric regions. Due to the lack of solar heating and very strong radiative cooling from carbon dioxide, the mesopause is the coldest region on Earth with temperatures as low as -100°C.

Stratosphere

Now is the stratosphere. It is the layer of the earth's atmosphere above the troposphere (and is below the mesosphere), extending to about 32 miles above the earth's surface.

Troposphere

Now after the stratosphere is the troposphere. It is the lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7-6.2 miles, which is the lower boundary of the stratosphere.

The earth's atmosphere is pretty amazing. So that is all the earth's atmospheres out there in space. With first staring with exosphere,thermosphere,mesosphere,stratosphere, and finally the troposphere.
