• true
• false

What is the greenhouse effect?

• The warming of a planet due to trapped radiation.
• The cooling of Earth due to air pollution.
• The heating of a solid, such as a rock.

What happens to the temperature if more greenhouse gases are released into the atmosphere?

• Temperature goes up
• Temperature goes down

Which of the following does NOT happen to solar energy when it reaches Earth?

• Some solar energy reflects off the atmosphere, back to space

• Some solar energy passes through Earth and comes out the other side

• Some solar energy is absorbed by land and water

• Some solar energy is radiated from the Earth's surface and trapped by the atmosphere

Increased carbon dioxide may cause global warming by

• allowing more sunlight into the atmosphere.
• reflecting more sunlight from clouds.
• reducing the amount of oxygen in the air.   
• trapping more heat in the atmosphere.

The greenhouse effect is a natural process
