Layers of Earth’s Atmosphere NotesLayers of Earth’s Atmosphere are divided based on:

Changes in TEMPERATURE

atmospheric boundary layer = “pause”

Tropopause: 12 km

Stratopause: 50 km

Mesopause: 80-83 km

Layers of the Atmosphere NotesTroposphere: weather present; where planes fly; sunlight warms earth surface & air above surface.

Stratosphere: ozone (O3 gas; 3 atoms of oxygen) present; traps solar energy “ invisible blanket”; warms stratosphere.

Mesosphere: thick layer; most meteoroids (asteroids, comets) burn up; loss of ozone.

Thermosphere: temperature increase due to O2 and N2 molecules interact with solar energy to form heat.

Ionosphere (lower): ions (charged particles) reflect radio waves back to Earth and produces the Aurora Borealis (Canada’s northern lights).

Exosphere (upper): cell phone/TV communication satellites
