Air Masses and Fronts KAP/GT

A student models convection currents in a laboratory activity.

• The warm air in Earth's atmosphere and the warm water in Earth's ocean sink instead of rise.

• The heat source for Earth's atmosphere and oceans is the sun, which heats from above instead of below.

• Convection cells in Earth's atmosphere and oceans flow in the same direction instead of opposite directions.

• Cold air in Earth's atmosphere and cold water in Earth's oceans are less dense than warm air and warm water instead of being more dense.
