In the Pacific Ocean, off the west coast of
South America, many people depend on
fishing for food and jobs. In this area,
winds blow warm surface water away from
the shore causing cold, deep ocean water

the surface. This process is known as ___.

B.
C.
D.
upwelling.
a surface current.
the Coriolis effect.
El Nino.
