Homework Club Tuesdays in P-11 (3:40-4:40) “It’s not enough to want to make the effort and to say we’ll make the effort. We must actually make the effort. It’s in the doing, not just the thinking, that we accomplish our goals.” Thomas Spencer Monson.

Why is the moon so much colder than the Earth if they are about the same distance from the sun?

Why is the moon so much colder than the Earth if they are about the same distance from the sun? Because the Earth’s atmosphere traps in heat.

Atmosphere: A blanket of gases surrounding the Earth (or any other planet)

Most common gases in the atmosphere: Nitrogen (N 2 ) 78% of atmosphere No color. No smell. Harmless to humans.

Most common gases in the atmosphere: Oxygen (O 2 ) 21% of atmosphere No color. No smell. Necessary for most forms of life on Earth.

Most common gases in the atmosphere: Argon (Ar) 1% of atmosphere Does not react with anything.

Greenhouse Effect: When certain gases in the atmosphere keep heat (infrared) near Earth and prevent it from going back into space.

Greenhouse Gas: A gas that traps heat near the Earth.

Most common greenhouse gases in the atmosphere: Carbon Dioxide (CO 2 ) less than 1% of atmosphere Given off by animals, cars, factories, burning things.

Most common greenhouse gases in the atmosphere: Water vapor (H 2 O) less than 1% of atmosphere Water in gas form like steam (forms clouds, rain, snow)

Most common greenhouse gases in the atmosphere: Methane (CH 4 ) less than 1% of atmosphere Flammable. Smells. Given off by animals (Gas responsible for farts).
