What causes climate?
Terms in this set (17)
Name two main factors that determine the climate of a region.
Temperature and Precipitation
year-after-year patterns of temperatures precipitation, winds, and clouds., Overall weather in an area over a long period of time
What are the main factors that influence temperature?
Latitude, altitude, distance from large bodies of water, and ocean currents.
What are the main factors that influence precipitation?
Prevailing winds, and presence of mountains.
The different seasons are the result of what?
The tilt of Earth's axis as Earth travels around the sun.
what are earths three main temperature zones called?
The tropical zone, polar zone, and temperate zone
Located near the equator, this area receives direction sunlight year round making the climate almost always warm.
cold climate zone where the sun's rays strike Earth at a very low angle
Climate zones with moderate temperatures that are located between the tropics and the polar zones
Latitude affects climate and temperature why?
Climates farther from the equator are cooler than climates closer to the equator. This is because the suns rays that hit the Earth's surface are spread out over a larger area giving less warmth.
What effect do oceans have on the temperature of nearby land areas?
They make the temperatures less extreme. Water heats up and cools down more slowly than land, winds from the ocean keep coastal regions from extremes of hot and cold.
Altitude affects climate and temperature why?
The temperature of the troposphere decreases several degrees for each kilometer of altitude. Highland areas everywhere have cool climates no matter what there latitude.
The side of a mountain range that faces the oncoming wind.
Facing away from the direction from which the wind is blowing
Why does precipitation fall mainly on the windward side of a mountain?
When humid winds blow from the oceans toward mountains they must rise up to pass over the mountains. The rising warm air cools when it rises and its water vapor condenses, forming clouds rain or snow falls on the windward side of the mountain.
Climate within a small area that differs significantly from the climate of the surrounding area
How do prevailing winds affect the amount of precipitation an area receives?
Air masses are moved from place to place by prevailing winds. (directional winds that usually blow in a region) Air masses can be warm or cool, dry or humid. The amount of water vapor in the air mass influences how much rain or snow will fall.
