Why is it called "The Greenhouse Effect"?

• Because greenhouse gasses protect Earth from UV radiation like a greenhouse protects plants from bad weather.

• Because greenhouse gasses trap heat on Earth's surface like a greenhouse traps heat to keep plants warm.

• Because greenhouse gasses reflect sunlight away from Earth like a greenhouse keeps plants in shade.

• Because greenhouse gasses allow heat to pass through them like a greenhouse allows light to pass through for the plants to do photosynthesis.

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.
