Oasis - small area in a desert where water and vegetation are found.

Natural Vegetation - plant life that grows in a certain area if people have not changed the natural environment.
 * There are more animals in the oasis of the desert.

Rain Shadow - result of a process by which dry areas develop on the leeward sides of mountain ranges.
 * Wheat is a natural vegetation to North Dakota.

Leeward - being in or facing the direction toward which the wind is blowing.
 * There is less vegetation in the rain shadow due to less percipitation.

Windward - being in or facing the direction from which the wind is blowing.
 * When I stand leeward the wind is in my face and im cold.

El Nino - a periodic reversal of the pattern of ocean currents and water temperatures in the mid-Pacific region.
 * When I stand windward the wind blows my hair over my head.


 * El nino is one of the main problems in our environments.

__**Tropic Of Cancer:**__ The Northerenmost point on the Earth. __**Example:**__ That recieve the direct rays of the sun. __** Greenhouse Effect: **__ Traps the sun's energy for growing plants even in cold weather and Earth would be to cold for living things. __ **Example:** __ COMM engineering is a world leader in greenhouse gas. __** Global Warming: **__ The burning of fossil fuels into the Earth's atmosphere causing heat to stayed trapped in the atmosphere. __** Example: **__ Because of our cars and the way we treat our world. The cold places are becoming warm, and that's not right for thoughs people and animals. __** Low Latitude: **__ Between 30 degrees South and 30 degrees North latitude. **__Example:__** is a zone which includes Tropic of Capricorn, Equator, and the Tropic Of Cancer. __** High Laatitude: **__ From 60 degrees North to 90 degrees North and from 60 degrees South to 90 degrees South. **__Example:__** The Earth's polar areas which then strecth out.

 * Antarctic Circle - ** Experiences continuous daylight ot twilight for the other six monthes of the year.
 * Midlatitudes - ** Generally have a temperate climate, one that ranges from fairly hot to fairly cold, which dramatic seasonal weather changes.
 * Prevailing Winds ** - Wind in a region that blows in a fairly constant directional pattern.
 * Coriolis effect ** **-** The resulting diagonal movement, either north or south, of prevailing winds caused by the Earth's rotation.
 * Doldrums ** - A frequently windless area near the Equator.
