Global Wind Patterns

What role does the sun play in wind formation?

• The sun causes the Earth to rotate, which creates wind patterns.

• The sun heats the Earth's surface unevenly, creating areas of high and low pressure that lead to wind formation.

• The sun's rays directly push air molecules, generating wind.

• The sun's position in the sky determines the direction of wind flow.

What are trade winds?

• Tropical winds that blow from 0 to 30 degrees latitude, primarily from east to west.

• Winds that occur in polar regions and blow from west to east.

• Winds that blow from the equator to the poles, varying in direction.

• Local winds that change direction based on the time of day.

What is a jet stream?

• A type of cloud formation found in the atmosphere.

• A fast-flowing air current found in the atmosphere, typically at high altitudes, that influences weather patterns.

• A weather phenomenon that occurs only during summer months.

• A low-pressure system that causes storms.

What causes differences in air pressure?

• The uneven heating of the Earth.

• The rotation of the Earth.

• The presence of mountains and valleys.

• The amount of moisture in the air.

What instrument measures air pressure?

• A barometer

• A thermometer

• A hygrometer

• An anemometer

What are the subtropical westerlies?

• Winds that blow from the east in the polar regions

• Winds that blow from the west in the subtropical regions, typically between 30 and 60 degrees latitude.

• Winds that blow from the north in the equatorial regions

• Winds that blow from the south in the temperate regions

How do ocean currents affect wind patterns?

• They have no effect on wind patterns.

• They can influence wind patterns by transferring heat and moisture, affecting local and global climates.

• They only affect ocean temperatures, not wind.

• They create storms that change wind directions.

What are the polar westerlies?

• Winds that blow from the east in the polar regions

• Winds that blow from the west in the polar regions, typically between 30 and 60 degrees latitude.

• Winds that blow from the north in the polar regions

• Winds that blow from the south in the polar regions

Where does the energy that creates winds come from?

• The moon

• The sun

• Volcanic activity

• Ocean currents

What is the role of topography in wind patterns?

• Topography has no effect on wind patterns.

• Topography can create barriers that redirect winds, such as mountains causing rain shadows.

• Topography only affects temperature, not wind patterns.

• Topography influences wind patterns by increasing humidity levels.
