Why Do Seasons Occur?
Seasons occur because of the change in how high the sun is in the sky. The sun is highest for the northern hemisphere on June 21st and lowest on December 21st. This is the exact opposite for the southern hemisphere.
Absorbing and Storing Heat
Different materials such as land and water absorb and store heat at different rates. So different areas globally and locally will vary in temperature based terrain and natural bodies of water.
Quick Note: I need to also study air is demo sheet along with the properties of air sheet, Types of energy sheet.

List the layers of the atmosphere:
Troposphere, Stratosphere, Mesosphere, and Thermosphere- Ionosphere and Exosphere
Uneven Heating
Uneven heating of the earth's atmosphere, land and water lead to movements of the waters and air. These movements determine climate and weather.
Why do we split up the atmosphere into layers?
We split the layers up by how the temperature behaves as you move through the layers.
Troposphere
The layer where we live. Weather happens here. Regular jets fly at the top of the troposphere. Temperature decreases as you move up.
Stratosphere
The ozone layer exists here. It absorbs harmful UV (ultra violet). Temperature increase as you move up.
Mesosphere
Most meteors burn up here. Temperature decreases as you move up.
Thermosphere
The first part of the atmosphere in which the suns energy hits. made up of the ionosphere, home to the aurora borealis and the exosphere, where there are communication satellites. Temperature rises as you move up.
What is wind?
Moving air.
Why does wind blow?
Wind blows because of uneven heating of the atmosphere.
Global winds
Global winds cover a large region and don't usually change.
Local Winds
Local winds cover a small region and change more often than global winds.
Air is...
21% Oxygen, 78% Nitrogen, 1% Argon, C02 and others, 0-4% water
