Global Wind Patterns and Their Effects on Weather

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, detailing their characteristics, formation, and effects on weather and climate.

What causes the global wind patterns on Earth?

• The Earth's magnetic field

• The uneven heating of the Earth

• The even heating of the Earth

• 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 Southwest

• From the Northwest

Between which latitudes are the westerlies found?

• 0 and 30 degrees

• 0 and 60 degrees

• 30 and 60 degrees

• 60 and 90 degrees

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

• They cause droughts

• They bring moist air, leading to rain and snow

• They create high pressure areas

• They cause hurricanes

What is the primary cause of the trade winds' direction?

• The Earth's tilt

• The gravitational pull of the sun

• The Coriolis effect

• The Earth's magnetic field

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

• At 60 degrees latitude

• At 30 degrees latitude

• At the equator

• At the poles

What is a characteristic of the doldrums?

• Cold temperatures

• Very little wind

• High pressure

• Strong winds

What is the historical significance of the horse latitudes?

• They were the first areas to be mapped

• They were known for their strong winds

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

• They were named after a famous explorer

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

• Due to the high temperatures

• Because of the high humidity

• Due to the sinking dry air

• Because of the frequent rainfall

What type of pressure is associated with the horse latitudes?

• Variable pressure

• No pressure

• High pressure

• Low pressure
