This type of renewable energy uses sunlight to make electricity.

What is solar power?

100

This gas is released when coal, oil, and gas are burned and helps trap heat in Earth’s atmosphere.

What is carbon dioxide?

100

Using energy from the sun, wind, or water instead of fossil fuels helps reduce this problem.

What is climate change?

200
True or False: The Greenhouse Effect allows heat or infared energy from Earth's surface to pass directly out through the atmosphere and back into space.
False
200

This human activity is one of the biggest sources of extra carbon dioxide in the atmosphere.

What is burning fossil fuels?

200

Wind turbines create electricity by using the power of moving this.

What is air (wind)?

TRUE

300
Which planet has an atmosphere with an extreme greenhouse effect?
Venus
300
True or False: Leaving electronic devices plugged in or on standby when you are not using them increases your carbon footprint.
True
300

This renewable energy source uses moving water, often from dams, to generate electricity.

What is hydropower?

300

This country emits the most carbon dioxide per person.

What is the United States?

300

400

This is one major environmental benefit of using renewable energy instead of fossil fuels.

What is reducing pollution?

400
What were carbon dioxide levels like during the last Ice Age?
much lower than they are today
400

This natural process allows plants to remove carbon dioxide from the air using sunlight.

What is photosynthesis?

500

True or False: Without the Greenhouse Effect, Earth's temperature would be unsuitable for most forms of life because it would be too cold.

True

500

These help reduce carbon dioxide by storing it instead of releasing it into the air.
