Mesosphere - Part II 5. Odyssea - Part II 7. Odyssea - Solar Wind 8. Ionosphere - Part II 10. The Troposphere is responsible for our weather.
Clouds form, electrical disturbances occur and the temperature decreases with altitude.
Stratosphere rests above the Troposphere. The air currents here are more stable then any other atmospheric layer, so it's a good place to fly your spacecraft. Mesosphere is the coldest layer in our atmosphere. So cold that Ice clouds form and sometimes can be seen in sunsets from the planet's surface. Mesosphere extents about 50 miles above the earth.
