3.3 Greenhouse Effect

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

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.

What is the source of energy for the Earth's water cycle?

• Sun's radiation
• ocean currents
• trade and prevailing winds
• Moon's gravitational attraction

Which statement accurately compares the heating and cooling rates for water and land?

• Water heats up and cools down at a faster rate than land.
• Land heats up and cools down at a slower rate than water.
• Water heats up and cools down at a slower rate than land.
• Land and water heat up and cool down at the same rate.

What is the greenhouse effect?

• The warming of a planet due to trapped radiation.
• The cooling of Earth due to air pollution.
• The heating of a solid, such as a rock.

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

• Urethane
• Oxygen
• Carbon Dioxide

 Which of the following activities contributes the most to carbon emissions globally?

• Deforestation
• Agriculture
• Burning fossil fuels
• Respiration
