No other planet in the solar system has the unique combination of fluids which Earth does. Earth has a surface that is mostly covered with liquid water, water vapor in the atmosphere, and both frozen and liquid water on the land.
Large Bodies of Water – moderate coastal climates because water keeps heat longer!
Kansas, NE, IA, Syracuse San Francisco, LA, DC Example: Colder than Ave. (Harsh) Warmer than Ave. (Mild) Winters: Warmer than average (HOT) Cooler than Average (Mild) Summers: LAND OCEAN Winds from: Interior (land) Ocean/large lake Location: Continental Marine
Orographic Effect – Mountains act as barriers to prevailing winds. As the wind hits the windward side of a mountain, the air is forced up, cools, condenses and forms clouds with precipitation.
Windward side – Side of the mountain that is exposed to the wind. WET
Leeward Side – Descending air warms and it holds more moisture, making it DRY .

The "Global Conveyer Belt" shows how the oceans move energy from the tropics to the poles and back again in order to moderate Earth's climate. This is accomplished through long-term ocean circulation.
Interesting fact: It takes up to 1000 years for water to completely circulate the oceans!
Uneven heating of the Earth produces global wind belts and pressure belts. These “pressure belts” determine the wetness or dryness of a particular location. Low pressure occurs where air is rising and thus precipitation occurs. High pressure regions are areas that lack rainfall (DRY).
