Differences in the temperature between the North and South poles and the equator create thermal currents in the atmosphere that form global winds.What is the source of energy for these currents?

• equator
• moon
• Sun
• tides

What are all of the climate zones that result from the unequal heating of Earth?

• tropical and polar
• temperate and polar
• temperate and tropical
• tropical, temperate, and polar

What occurs when cool air moves from the ocean toward the beach during the day?

• a land breeze
• a prevailing wind
• a sea breeze
• an updraft

The diagram represents solar energy that is absorbed by Earth's land and water surfaces and is changed into heat that radiates back into the atmosphere.What is this process called?

• ozone
• radiation
• greenhouse effect
• evaporation

The map shows the major atmospheric convection areas.Which zones are temperate regions?

• V and Z
• X and Y
• W and Y
• Z and X

Which process accurately describes the formation of the greenhouse effect?

• The Sun's rays are reflected from the land back into the atmosphere.
• Increased solar energy is entering through the hole in the ozone layer.
• Aerosol gases become trapped and build up in the atmosphere.
• Heat radiating from the land and oceans is trapped in the troposphere.

Solar energy is best absorbed by what material?

• dirt
• sand
• snow
• water

The oceans make up 70% of Earth's surface. They regulate the overall temperature of the earth by absorbing a great deal of solar energy and heating up slowly. What is true about the oceans' release of heat?

• The oceans release heat rapidly and add to the greenhouse effect.
• The oceans release heat more slowly than the land.
• The oceans release heat more rapidly than the land.
• The oceans release heat at the same rate as the land.

The tropical regions are warmer than the polar regions due to the angle of the Sun's rays. As a result, there is generally higher pressure at the poles and lower pressure at the equator, so which way does the wind blow on the Earth's surface?

• The wind blows cold air toward the equator from the poles.
• The wind blows warm air from the poles to the equator.
• The wind blows cold air from the equator to the poles.
• The wind blows warm air from the equator to the poles.

The horizontal line on the map represents the equator.In which major climate zone is the equator located?

• polar
• subtropical
• temperate
• tropical
