Global Winds and Local Winds

Wind is caused by:

• The rotation of the Earth

• Differences in air pressure

• The phases of the moon

• The pull of gravity

The Coriolis effect is:

• the apparent deflection of moving objects due to Earth's rotation

• the force that keeps planets in orbit around the sun

• the process of water evaporating from the ocean

• the movement of tectonic plates

All the air on Earth is not at the same temperature because:

• The Sun heats different parts of Earth unevenly.

• Air is made of different gases.

• The Earth is flat.

• There is no atmosphere.

In areas of high pressure, air is:

• rising

• sinking

What are the three main global wind belts?

• Trade winds, westerlies, polar easterlies

• Monsoons, cyclones, anticyclones

• Jet streams, doldrums, hurricanes

• Sea breezes, land breezes, mountain winds

Describe: Fill in the blanks in the table. Wind belt: Trade winds | Location (latitude): 0° to 30° | Toward the equator or toward the poles?: toward the equator Wind belt: Westerlies | Location (latitude): 30° to 60° | Toward the equator or toward the poles?: toward the poles Wind belt: Polar easterlies | Location (latitude): 60° to 90° | Toward the equator or toward the poles?: toward the equator

• Westerlies: 30° to 60°, toward the poles Polar easterlies: 60° to 90°, toward the equator

• Westerlies: 0° to 30°, toward the equator Polar easterlies: 30° to 60°, toward the poles

• Westerlies: 60° to 90°, toward the equator Polar easterlies: 0° to 30°, toward the poles

• Westerlies: 30° to 60°, toward the equator Polar easterlies: 60° to 90°, toward the poles

Use the map to explain why surface winds are generally very weak near the equator.

• Because the equator receives direct sunlight all year round.

• Because the Coriolis effect is strongest at the equator.

• Because the equator is an area of low pressure where air rises, causing weak surface winds.

• Because the equator is surrounded by mountains that block the wind.

Earth's rotation affects the paths of global winds by:

• Causing winds to move in straight lines from poles to equator

• Making winds curve due to the Coriolis effect

• Slowing down the speed of all winds

• Stopping winds from moving across the equator
