What is the Greenhouse Effect?

Back

The Greenhouse Effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space, which keeps the planet warm.

Front

Give a real-world example of the Greenhouse Effect.

Back

A car parked in the sun heats up because sunlight enters the car but the heat cannot escape, similar to how greenhouse gases trap heat in the atmosphere.

What is a renewable resource?

Back

A renewable resource is a natural resource that can be replenished naturally over time, such as solar energy, wind energy, and biomass.

Front

What is a nonrenewable resource?

Back

A nonrenewable resource is a natural resource that cannot be replenished in a short period of time, such as coal, oil, and natural gas.

Front

Is coal a renewable or nonrenewable resource?

Back

Coal is a nonrenewable resource.

Front

Is oil a renewable or nonrenewable resource?

Back

Oil is a nonrenewable resource.

Front

Is wind a renewable or nonrenewable resource?

Back

Wind is a renewable resource.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat, including carbon dioxide, methane, and nitrous oxide.

Front

What has been the major source of greenhouse gases since 1990?

Back

Carbon dioxide has been the major source of greenhouse gases since 1990.

Front

What is the impact of deforestation on greenhouse gases?

Back

Deforestation increases greenhouse gases because trees absorb carbon dioxide; when they are cut down, the stored carbon is released back into the atmosphere.
