What is the structure of the atmosphere?
Parts
Exosphere
Above 600 km
Extends to about 10,000 km in height
But there is no clear boundart
Thermosphere
Ionosphere
600 km to 85 km
Contains most satellites
High temperaures
Mesosphere
From 85 km to 50 km
Gases slow down meteoroids
Stratosphere
Between 50 km and 12 km
Contains Ozone layer
1% atmosphere's mass remains
Troposphere
From the Earth's surface
To 12 km higher
Thicker at the Equador
Than the poles
80% of the mass of atmospheric air is here
Satellites and other things in the atmosphere
Ariane 5 rocket
Designed by European Space Agency
Experimental aeroplane X43
Aerostatic ballons
Used by scientist
To obtain information about atmosphere
Meteroids
Commercial airplanes
Altitude of 10,000 m
Mountains

8,848 m in height
the International Space Station ( ISS)
