Wind Currents Lesson

Use the following slides to fill out your notes on page 8!

Multiple Choice

Where does the initial source of energy come from that creates winds?

• the moon
• the sun
• the Earth's surface
• the rotation of the Earth

Multiple Choice

What causes wind currents on Earth?

• Differences in ocean salinity

• Uneven heating of the Earth by the sun

• Earth's magnetic field

• Rotation of the moon

Multiple Choice

The sun's rays are least direct at the

• land near the equator.

• oceans and other large bodies of water.

• at high altitudes.

• near the poles.

Multiple Choice

Which of the following best explains why air rises at the equator?

• The equator receives direct rays from the Sun, warming the air.

• The equator is at a higher altitude than other regions.

• The equator has more vegetation.

• The equator has stronger winds.

Fill in the Blank

Air that moves towards the pole meets very cold polar air and rises at ___°N and ___°S.

Multiple Choice

How does wind blow on Earth?

• From high pressure toward low pressure latitudes

• From low pressure toward high pressure latitudes

• From East to West

Multiple Choice

At which latitudes does cool air sink in the Earth's atmosphere?

• 0°

• 30°N and 30°S

• 60°N and 60°S

• 90°N and 90°S

Multiple Choice

Which of the following is true about the weather in low and wet belts?

• They experience rainy weather due to rising air and precipitation.

• They are always dry and have little cloud formation.

• They are found only at the equator.

• They have high pressure and sinking air.

Multiple Choice

What is the difference between low and wet belts and high and dry belts that wrap around Earth?

• Low and wet belts are dry and barren, while high and dry belts are lush and green.
• Low and wet belts are cold and icy, while high and dry belts are warm and humid.
• Low and wet belts are mountainous and rocky, while high and dry belts are flat and fertile.
• Low and wet belts are humid while high and dry belts are arid.

Multiple Choice

Which latitudes are associated with 'high and dry' wind belts, and what causes these conditions?

• 30°N and 30°S; caused by sinking air creating high pressure

• 0° and 60°N; caused by rising air creating low pressure

• Equator and poles; caused by solar radiation

• 30°N and 60°S; caused by cold air descending

Multiple Choice

What are prevailing winds?

• Global winds that blow constantly but always change their direction

• Global winds that blow constantly in the same direction

• Global winds that always blow from East to West

• Local winds that are really strong

Multiple Choice

Explain how prevailing winds influence the climate of a region.

• Prevailing winds have no effect on local weather conditions.
• Prevailing winds influence climate by transporting air masses that affect temperature and precipitation patterns in a region.
• Winds primarily influence ocean currents, not climate.
• Climate is determined solely by geographical features, not winds.

Multiple Select

Which of the following statements about prevailing winds is/are correct?

• Prevailing winds blowing from warm regions carry humid air.

• Prevailing winds blowing from cold regions carry dry air.

• Prevailing winds always carry wet air regardless of origin.

• Prevailing winds do not affect air moisture.

Fill in the Blank

Locations along and near the ___ are hot, humid, and wet due to prevailing winds.

Multiple Choice

How do wind currents influence the location of biomes on Earth?

• Wind currents determine the temperature of biomes directly.

• Wind currents affect the distribution of moisture and temperature, influencing biome locations.

• Wind currents have no impact on biomes.

• Wind currents only affect ocean currents, not biomes.
