ESS.7.2.2 - Greenhouse Effect

Which of the following gases is NOT considered a greenhouse gas?

• Carbon dioxide

• Oxygen

• Methane

• Water vapor

What is the main function of the ozone layer in the stratosphere?

• Produces greenhouse gases

• Absorbs ultraviolet radiation

• Causes global warming

• Increases atmospheric pressure

Which layer of the atmosphere is located directly above the mesosphere?

• Troposphere

• Stratosphere

• Thermosphere

• Exosphere

What term describes the overall weather in an area over a long period of time?

• Weather

• Climate

• Greenhouse effect

• Ozone

Which of the following best defines the greenhouse effect?

• The process by which plants grow in a glass house

• The trapping of heat in Earth's atmosphere by certain gases

• The increase in Earth's average temperature

• The movement of air in the stratosphere

Which of the following is a direct result of the greenhouse effect?

• Decrease in atmospheric pressure

• Retention of heat in Earth's atmosphere

• Formation of clouds

• Increase in oxygen levels

If the ozone layer in the stratosphere were to become thinner, what would most likely happen?

• More ultraviolet radiation would reach Earth's surface

• The greenhouse effect would stop

• The thermosphere would cool down

• There would be more rainfall

Which of the following scenarios best illustrates global warming?

• A sudden thunderstorm in summer

• A gradual increase in Earth's average temperature over several decades

• A cold winter day

• The formation of the ozone layer

Explain how an increase in greenhouse gases could affect Earth's climate over time.

• It would cause more rain in deserts

• It could lead to a rise in average global temperatures, resulting in climate changes

• It would make the stratosphere thicker

• It would decrease the amount of water vapor in the air

A scientist observes that the temperature in the thermosphere increases with altitude. What reasoning best explains this phenomenon?

• The thermosphere is closer to the sun

• The thermosphere absorbs high-energy solar radiation, causing temperatures to rise with altitude

• The ozone layer is located in the thermosphere

• There are more greenhouse gases in the thermosphere
