Ocean currents

  1. 1. Ocean Currents Ocean water moves in currents What causes ocean currents? How do ocean currents distributeheat around the globe and interact with climate and weather?
  2. 2. Surface currents are caused bystrong winds blowing over theocean.They extend 300-500 feet downCover large areas of oceanThey curve with the rotation of EarthThey carry warm water away from equator and cool water away from the polesThey effect Earth’s temperatures
  3. 3. Deep Currents are caused bydifferences in the density of thewater. Downwelling is water movement from the surface down. This movement carries oxygen from the surface to animals deeper in the ocean.
  4. 4. Upwelling Upwelling moves water down deep up to the surface. This movement bring up nutrients to the animals at the surface
  5. 5. Climate and WeatherCurrents help distribute heat around the globe by moving warm and cold water around.The moving water changes the temperature of the air above it.
