Greenhouse gases are important to our planet's survival because...

• They create a natural cooling effect that keeps us from burning up.

• They fuel the cars we drive.

• They create oxygen which we need to breathe.

• They keep our earth warm so we can sustain life.

Why are too many greenhouse gases bad for the environment?

• They cause trees to die.

• They release heat and will be the cause of the next ice age.

• They trap heat in our atmosphere causing the planet to warm up.

• They are fossil fuels which pollute our environment.

Choose all of the following that are alternative (greener) energy sources...

• The sun

• Wind

• Electricity

• Water

What is global warming?

• a gradual increase in the overall temperature of the earth's atmosphere.

• a change in global or regional climate patterns

• the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land.

• The action of clearing a wide area of trees.

What is climate change?

• The trapping of the sun's warmth in a planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.

• a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, and other pollutants.

• The action of clearing a wide area of trees.

• a change in global or regional climate patterns, in particular a change attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
