Which of the following best describes the greenhouse effect?

• The process in which certain gases trap sunlight in Earth's atmosphere as heat.

• The process in which plants convert sunlight into energy.

• The process in which the Earth's core generates heat.

• The process in which water vapor condenses to form clouds.

Explain how the greenhouse effect can impact Earth's climate. Use evidence from the definition provided.

• By trapping more heat, the greenhouse effect can lead to an increase in Earth's average temperature.

• By reflecting sunlight, the greenhouse effect cools the Earth's surface.

• By absorbing all sunlight, the greenhouse effect prevents plant growth.

• By increasing rainfall, the greenhouse effect causes more flooding.

Which of the following is NOT listed as a potential factor that affects climate?

• Variations in Earth’s orbit

• Volcanic activity

• Increase of carbon dioxide in the atmosphere

• Photosynthesis in animals

How do higher concentrations of greenhouse gases affect the Earth's climate?

• They cool the Earth's surface

• They trap more heat in the biosphere, leading to climate change

• They reduce precipitation

• They decrease the frequency of storms
