What happens to temps throughout layers of the atmosphere? - Sigma Graph
Vary - Cool to Warm to Cool to Warm
What is a pause?
It is when the temps level out - Tropopause, Stratopause, and mesopause.
Roots for each layer of atmosphere
Tropo - Change, Strato - Layers, Meso - Middle, Iono - Charged Particle, Thermo - Heat, Exo - Outside

What are light shows called? How do they happen?
Aurora Borealis - in the Northern Hemisphere
Aurora Australis - in the Southern Hemisphere
When a stream of ions interact with solar wind and hit the magnetosphere and travel along field lines.
How many satellites are there?
Approximately 4,000
What layer are satellites in?
The exosphere
What are meteoroids?
All broken rock and metal in the mesosphere
What are meteors?
The stage after meteoroids where the rock and metal burns
