Greenhouse Effect Review

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in the Earth's atmosphere that trap heat. Key examples include carbon dioxide, methane, and water vapor.

Front

How do greenhouse gases contribute to global warming?

Back

Greenhouse gases contribute to global warming by trapping heat in the atmosphere, preventing it from escaping back into space.

Front

What is the effect of increased greenhouse gases on Earth's temperature?

Back

Increased greenhouse gases lead to a rise in Earth's temperature.

Front

True or False: All radiation from the Sun is absorbed by the Earth.

Back

False. Not all radiation from the Sun is absorbed; some is reflected back into space.

Front

What causes the greenhouse effect?

Back

The greenhouse effect is caused by gases in the atmosphere trapping heat that is released by the Earth.

Front

Name three major greenhouse gases.

Back

Carbon dioxide, methane, and water vapor.

Front

What role does carbon dioxide play in the greenhouse effect?

Back

Carbon dioxide traps heat in the atmosphere, contributing to the greenhouse effect and global warming.

Front

What happens to the heat that the Earth releases at night?

Back

Some of the heat is trapped by greenhouse gases, preventing it from escaping into space.

Front

What is the relationship between human activities and greenhouse gas emissions?

Back

Human activities, such as burning fossil fuels and deforestation, increase greenhouse gas emissions, leading to global warming.

Front

How does deforestation affect the greenhouse effect?

Back

Deforestation reduces the number of trees that can absorb carbon dioxide, increasing the concentration of greenhouse gases in the atmosphere.
