The layers are:
Exosphere Farthest from Earth
Thermosphere
Mesosphere
Stratosphere
Troposphere Closest to Earth
Scientist divide the atmosphere into layers, depending on the gases present and the resulting differences in temperature.

Multiple Choice
Why does the air temperature change at different altitudes?
it gets hotter as you move toward the sun
It gets colder as you move away from Earth
some altitudes have more gases to absorb solar energy than others
some altitudes receive less sunlight that others
