What is the general pattern of winds at the equator?

• Winds are generally strong because the equator is a region of mostly low air pressure

• Winds are generally weak because the equator is a region of mostly low air pressure

• Winds are generally strong because the equator is a region of mostly high air pressure

• Winds are generally weak because the equator is a region of mostly high air pressure

Which heats up and cools more quickly?

• Land

_________ is the transfer of heat by direct contact. Warm air is less dense, so it rises above cold air.

• Conduction

• Convection

• Radiation
