What is upwelling?

• The rapid decrease in temperature with depth

• The movement of water at an angle to the wind

• The rise of deep, nutrient-rich water to the surface

• The process of warm water sinking

What is the thermocline?

• The global system of deep ocean currents

• A layer where salinity changes rapidly with depth

• A layer where temperature decreases rapidly with depth

• The deflection of currents due to Earth's rotation

What is El Niño?

• The process of carbon dioxide absorption by oceans

• A climate pattern with cooler-than-normal surface waters

• A climate pattern with warmer-than-normal surface waters

• The movement of nutrients through ocean currents
