Why does it tend to be cool at the Earth's poles?

• They are farthest from the sun

• They have high absolute humidity

• They have the worst weather

• Sunlight strikes them at extreme angles

How does radiation heat something?

• infrared or electromagnetic waves transfer energy from one object to another

• Energy is transferred by one object touching another

• energy is transferred by the rising and sinking of air currents

• it uses electricity
