______forms because of the unequal heating of Earth.

• doldrums

• wind

• troposphere

• equator

Land breezes and sea breezes are examples of local winds.

• false

• true

The ____are winds that blow from west to east between the latitudes 30 degree and 60 degree in both hemisphere.

• polar easterlies

• prevailing westerlies

• trade winds

• easterlies

A local wind that blows in the day from higher pressure over the sea toward lower pressure over land is a(n)

• land breeze

• sea breeze

Between which latitudes are the trade winds found?

• between 30 degrees North and 30 degrees South

• between 60 degrees North and 20 degrees South

• only at the polar easterlies

• between 30 degrees North and 60 degrees North

In which direct do trade winds blow?

• from south to southeast

• from north to northeast

• from northeast to southwest

Which of the following statements relating to air pressure is correct?

• The temperature in the tropics results in high air pressure.

• Air pressure over the poles is usually high.

• Sunlight strikes at a high angle at the North Pole, causing a low pressure

What are the main wind belts on Earth?

• polar easterlies, ozone layer, exosphere

• polar easterlies, westerlies, trade winds

• trade winds, thermosphere, exosphere

How is a jet stream different from other global winds?

• flow at the top of the troposphere, move at extremely high speeds, and are moving erractic than other global winds.

• low at the bottom of the troposphere, move at slow speeds, and are moving erractic than other global winds.

• low at the middle of the troposphere, move at slower speeds, and are moving erractic than other global winds.

What does the H and L labels represent?

• The H represents an area in the Hydrosphere and L in the Lithosphere.

• The H represents an area of High pressure and L represents an area of Low pressure.
