The Exosphere
The last layer of the Earth's atmosphere is the exosphere. This is the area where the atoms escape into the espacio.La photo at left shows the Earth's atmosphere (it is likely that the clouds are in the troposphere and stratosphere), the edge of the planet (dark blue curve and the bank under the mesosphere and the thermosphere), all that done by the exosphere (the darker blue to black) which is continuous in space.
Thermosphere
The thermosphere is the fourth layer of the Earth's atmosphere. It is located above the mesosphere. At this point, the air is thin and the temperature change with solar activity. If the sun is active, the thermosphere temperatures can reach 1,500 ° C and even higher! Earth's thermosphere also includes the region called the ionosphere.
Mesosphere
The mesosphere is the third layer of the Earth's atmosphere. The temperature decreases as is raised, as in the troposphere. Can be up to -90 ° C. It is the coldest zone of the atmosphere! The mesosphere begins after the stratosphere. Sometimes, one can distinguish the mesosphere at the edge of a planet (as the blue band on right side of the picture.)
The
Stratosphere The stratosphere is the second layer of the Earth's atmosphere. As it rises, the stratospheric temperature increases. Ozone causes the temperature rises as it absorbs the sun's dangerous light and converts it into heat. The stratosphere is above the troposphere.
Troposphere
The troposphere is the bottom layer (closest to the Earth's surface) of the Earth's atmosphere. As it rises, lowers the temperature in the troposphere. In the troposphere occurring phenomena that make up what we call time.
