How does air move away from the poles and toward the equator?
Warm air near the equator rises and moves to the poles.
Cool air at the poles sinks and moves to the equator.
Warm air at the poles sinks and moves to the equator.
Cold air near the equator rises and moves to the poles.
Ocean currents bring warm water from the equator towards Earth's

Brings light rain/snow and warmer temperatures.
Cold Front
Gentle Front
Warm Front
Stationary Front

Major surface currents of the ocean are shown in the diagram.
Ocean currents affect weather patterns by--
Regulating when tides occur in coastal area
Trapping heat at the equator to regulate the global climate
Distributing heat from the uneven absorption of solar energy
Increasing the rate of evaporation to transport water to area experiencing droughts
