Essential Question: How does energy from the Sun drive wind and ocean currents?

2. Topic: Ocean Systems Essential Question: How does energy from the Sun drive wind and ocean currents?
Convection- is the transfer of heat through the movement of air or liquid. Warm matter rises, while cold matter sinks.

3. Topic: Ocean Systems Essential Question: How does energy from the Sun drive wind and ocean currents?
Wind is the movement of air due to changes in pressure and temperature.

4. Topic: Ocean Systems Essential Question: How does energy from the Sun drive wind and ocean currents?
Wind is caused by the uneven heating of the Earth’s surface putting convection currents in motion in the atmosphere.

5. Topic: Ocean Systems Essential Question: How does energy from the Sun drive wind and ocean currents?
Differences in air pressure cause air to move. Air moves from areas of high pressure to areas of low pressure. Warm air - low pressure Cool air- high pressure

6. Topic: Ocean Systems Essential Question: How does energy from the Sun drive wind and ocean currents?
Ocean currents are created by the sun, heating up the ocean creating a convection current. Warm water rises, cools off, and then sinks. Global winds move ocean currents around the globe.

7. Topic: Ocean Systems Essential Question: How does energy from the Sun drive wind and ocean currents?
Ocean currents circulate warm and cool water. Warm currents come from the equator. Cold currents come from the poles.

8. Topic: Ocean Systems Essential Question: How does energy from the Sun drive wind and ocean currents?
The Coriolis Effect The rotation of the Earth causes ocean currents to move to the right in the northern hemisphere and to the left in the southern hemisphere.
