Global Wind Patterns and Effects

The video explains global wind patterns caused by uneven heating of the Earth, pressure belts, and the Coriolis effect. It covers major wind types: polar easterlies, westerlies, trade winds, doldrums, and horse latitudes. Each wind type's characteristics, formation, and effects are discussed, including their impact on weather and climate. The video concludes with a summary of these global winds.

What causes the global wind patterns on Earth?

• The Earth's axial tilt

• The Earth's magnetic field

• Uneven heating of the Earth and the Coriolis effect

• The gravitational pull of the moon

In which direction do the polar easterlies blow in the Northern Hemisphere?

• From the Southeast

• From the Northeast

• From the Northwest

• From the Southwest

Between which latitudes are the westerlies found?

• 0 to 60 degrees

• 60 to 90 degrees

• 30 to 60 degrees

• 0 to 30 degrees

What is a significant effect of the westerlies on the United States?

• They cause droughts

• They lead to high temperatures

• They bring moist air, leading to rain and snow

• They create hurricanes

What is the primary direction of the trade winds in the Southern Hemisphere?

• Southwest

• Northeast

• Northwest

• Southeast

Where do the trade winds of the Northern and Southern Hemispheres meet?

• At the poles

• At 60 degrees latitude

• At 30 degrees latitude

• At the equator, in the doldrums

What is a characteristic of the doldrums?

• Strong winds

• High pressure

• Cold temperatures

• Very little wind

What is the historical significance of the horse latitudes?

• They were areas where ships often got stuck, leading to horses being thrown overboard

• They were the starting point for many trade routes

• They were named after a famous explorer

• They were known for their abundant wildlife

Why are many of the world's deserts located in the horse latitudes?

• Due to the presence of large rivers

• Because of frequent rainfall

• Due to the sinking dry air

• Because of the high humidity

What type of pressure is associated with the horse latitudes?

• Low pressure

• High pressure

• Variable pressure

• No pressure
