Conduction

How is heat transferred to you from a campfire?

Radiation

What type of heat transfer is responsible for heating the troposphere?

Convection

Why does convection happen?

d. Cold air is more dense than warm air

Wind is caused by differences in

a. Precipitation

b. Humidity

c. Air pressure

d. Turbulence

How are local winds different from global winds?

Local winds are caused by unequal heating in a small area

Why do land breezes form? Because land cools off faster than water
