Surface currents are mainly caused by

• The Coriolis Effect

• Cold and Warm Water

• Wind

When La Nina and hurricanes pull cold water to the surface and bring nutrient rich sediments from the seafloor, this is called ___________________.

Why do the fisherman of Peru and South America not welcome a strong El Nino?

• El Nino causes strong winds and currents which move fish westward

• El Nino bring cold water to the surface which kills the base of the food chain

• El Nino shuts off upwelling and nutrients needed for the marine food chain do not rise to the surface
