TRADE WIND

• Blows toward the equator from both north and south
• It shifts westward cause by the Earth rotating.
• When wind blows across the ocean they move water on the oceans surface
• Which makes the water move in circular patterns
• Then the sun warms the water up

TRADE WIND CONTINUED

• Once the warm water hit land, they have to turn
• In North Hemisphere the currents turn to the north
• In South Hemisphere the currents turn to the south
• When the current move away the equator they act like heating systems
