  1. Ocean Currents Ocean water moves in currents What causes ocean currents? How do ocean currents distribute heat around the globe and interact with climate and weather?

  2. Surface currents are caused by strong winds blowing over the ocean. • They extend 300-500 feet down • Cover large areas of ocean • They curve with the rotation of Earth (coriolis effect.mp4) • They carry warm water away from equator and cool water away from the poles • They affect Earth’s temperatures

  4. Deep Currents are caused by differences in the density of the water. Downwelling is water movement from the surface down. This movement carries oxygen from the surface to animals deeper in the ocean. Salinity and temperature

  5. Upwelling • Upwelling moves water down deep up to the surface. • This movementbrings up nutrients to the animals at the surface

  6. 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. • Beware of El Nino!What is El Nino.mp4

  7. Answer the following: • What causes ocean currents? • How do ocean currents distribute heat around the globe and interact with climate and weather?
