Climate Change

What gas from the list below is a cause for global warming?

• Urethane
• Oxygen
• Carbon Dioxide

Which is one cause for Global Warming we discussed today?

• Burning Fossil Fuels
• Pollution from factories
• Both are causes for Global Warming

Humans have the ability to cause temperature change.

• True
• False

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

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

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 gas that is most abundant in the atmosphere is

• oxygen
• nitrogen
• carbon dioxide
• argon
