11) name four forces or effects that can influence the wind

Tempeture, air pressure, centripetal acceleration and Earth rotation.

Temperature: Warm air and cold air have different density. As warm air is less dense than cold air, it rides up and over the cold air causing winds.  

Air Pressure: At the Earth's surface, wind blows horizontally from high pressure to low pressure areas. Wind is faster in bigger pressure differences.  

Centripetal Acceleration: air speed is influenced by centripital acceleration this way, the direction of wind in the center of the circulation is also influenced. Cyclones, for example, are a association of centripital acceleration and air pressure differences.

Earth's Rotation: Wind direction chance can be caused by the rotation of Earth on its axis. The Coriolis effect, easterlies are examples of the influence of the earth’s rotation on Wind.

within these regions are all the major types of biomes in the world. a biome is a community of animals and plants spreading over an extensive area with a relatively uniform climate. some diverse biomes represented in north america include desert, grassland, tundra, and coral reefs.
