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.
Which of the following could increase the amount of greenhouse gasses in our atmosphere?

Planting trees
Walking to school and work
Cutting down trees
If the Earth is like a greenhouse, carbon dioxide in the atmosphere is like
Plants

What might happen if the greenhouse effect didn't exist?
a. It would be too cold for humans to survive on the earth.
b. The earth's temperature would be much more comfortable.
c. The sun's rays would never reach the surface of the earth.
d. The earth wouldn't have an atmosphere.
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.
The layer that protects the earth from the ultraviolet rays of the sun is called ————————

What is the greenhouse effect?
A natural process where gases trap heat in the atmosphere.
A man-made process where gases trap heat in the atmosphere.
A natural process where the ocean traps heat in the atmosphere.
A man-made process where the ocean traps heat in the atmosphere.
How is the greenhouse effect produced?
When solar energy trespasses the atmosphere.
When some energy is reflected back to earth.
When the green house is burned.
When the sun doesn't emit radiation.
