El Nino effect

Hurricanes move in opposite directions in the northern and southern hemispheres due to ___________________.

• El NIno

• The Coriolis Effect

• La Nina

• upwelling

La Niña is characterized by ______________ of the Western Pacific Ocean.

• a warming

• a cooling

• average temperatures

______________ causes more rainfall in the Northwest United States and poor fishing off the coast of South America (Peru).

• La Nina

• El NIno

• El Baby Yoda

• La Chancla

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

• El Nino poisons the fish

• 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

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

• upwelling

• downwelling

• El zapato

• La Gloria
