Correctly draw a compass labeling all of the directions
north, east, south, west

What is the cause of wind?
Unequal heating of Earth’s surface
100
Describe the Jet Stream.
A narrow band of high winds, commonly located near the top of the troposphere; influences weather
200
Why were the trade winds and westerlies extremely important to merchant sailors in the past?
Merchant ships would use the trade winds to travel eastward from Europe to the Americans to trade goods. In order to return home the merchants would use the westerlies to travel westward.

A sea breeze ALWAYS occurs during the ___________ ?
A Sea breeze ALWAYS occurs during the DAY!
200
Lines of longitude run __________ to ___________
North to South
200
The Sun heats Earth’s surface unevenly because
The angle at which the Sun’s light strikes the surface
200
The Earth rotates ___________ to __________ .
West to East
300
Describe the Polar Easterlies.
Cold winds that blow from east to west near the North Pole and South Pole
300
Describe a land breeze
ALWAYS occurs during the NIGHT! Wind blows from the land toward the sea due to temperature and pressure differences.

The Equator is an example of a line of ________________ that runs east to west.
Latitude
300
The movement of air from areas of high pressure to areas of low pressure is called
Wind
300
In the Northern Hemisphere, the Coriolis effect causes moving air and water to appear to turn _____________.
Right
400
Describe the Westerlies.
Steady winds that flow from west to east between latitudes 30°N and 60°N and between latitude 30°S and 60°S.
400
True or False: All materials have the same exact specific heat.
FALSE! All materials have difference specific heats based on their composition.
400
Low pressure develops over the
Tropics
400
Global wind belts influence ____________ and ___________.
Climate and Weather
400
Describe doldrums
Areas of high pressure and light calm winds at about 30°N latitude and 30°S latitude
500
Describe the Trade Winds.
Steady winds that flow toward the equator from east to west between 30° N latitude and 30°S latitude.

Using the term Specific Heat, explain why the sand at the beach changes temperature drastically throughout the day but the ocean only changes temperature slowly.
The land and the ocean have different specific heats. The land has a lower specific heat thus heats up and cools down at a much more rapid pace (less energy is required). Water has a high specific heat thus heats up and cools down very slowly (requires a lot of energy)
500
High pressure develops over the _______________.
Poles
500
True or False: The three cells that scientists use to describe circulation of Earth’s atmosphere are conduction cells
FALSE! Convection Cells!

In the Southern Hemisphere, the Coriolis effect causes moving air and water to appear to turn ___________.
