Open Ended

What does "energy radiated back to space" mean?

Open Ended

What does "energy distributed around Earth" mean? How does it relate to climate change? (be sure to answer BOTH questions here!)

Open Ended

What are FOUR main ways that the amount of energy Earth receives from the sun can change over time?

Multiple Choice

How can gases in the atmosphere change the amount of energy that is radiated from Earth back into space?

• Some gases are shinier so they reflect more energy

• They can't

• Certain gases can reflect energy radiated by Earth back to the planet’s surface.

• The color of the gases affects the albedo which is how much they will reflect.

Multiple Select

Which one is a type of gas that will NOT radiate heat from the sun back to space, but instead absorb and trap more of the energy?

• Oxygen

• Carbon Dioxide

• Methane

• Hydrochloro-fluorocarbons
