Where is the ionosphere and exosphere

Structure of the atmosphere

Troposphere: It is the lowest area in which those processes take place that we call the term
Summarize "weather". Although it is the thinnest layer, 75-90 percent of the
Total mass of the atmosphere.
The troposphere, in which the temperatures decrease with increasing altitude by around 6.5 C per kilometer,
extends to
Tropopause, which is between 8 and 17 kilometers in altitude. Above is the

Stratosphere: Here the temperature rises with altitude and reaches its maximum around fifteen
Kilometers in altitude
(Stratopause). It contains around 90 percent of the total ozone, of which around three quarters are in the
so-called ozone layer, the altitude range between 15 and 20 kilometers.

Mesosphere: (Meso = medium; medium sphere) It ranges from 50 km to 80 km. She is called the cold layer
known because temperature and air pressure drop dramatically here. Because this sphere is above the ozone layer
is located, the UV light here is so strong that a human body can be severely burned
The mesopause lies above it.

Thermosphere: In the thermosphere, which extends up to 250 km above sea level, the temperatures rise
1300 F. At 100-200 km they are
The main components of the atmosphere are still nitrogen (nitrogen) and oxygen (oxygen).

Ionosphere: This layer, which has a large ion content, is part of the meso- and thermosphere.
Radio waves and light are reflected from here. These reflections cause those at the polar ones
Regions visible northern lights.

Exosphere: It is extremely thin and the furthest from Earth. This sphere is the transition zone
between the earth's atmosphere and space.
