Winds, known as trade winds, blow from east to west across the pacific ocean. these winds move water at the surface along the california coast nutrients that would normally stay at the bottom of the ocean rise to the surface as well.
which of the following conclusions is supported by the information above?
a) trade winds sustain some food chains.
b) trade winds produce minerals in some oceans.
c) trade winds can reverse parts of the water cycle.
d) trade winds may be able to reduce global warming.

A

Explanation:

The deep cooler currents in the oceans have more nutrients because of several factors;

When the trade winds push the warm waters towards the east, the cooler water from the bottom upwell (from the west in a cyclic fashion) to replace the displaced water by the winds. They bring with them nutrients and oxygen that is great ‘fodder’ for plankton. The plants are then fed on by smaller fish like shrimps. The smaller fish are then preyed on by bigger fish hence sustaining food chains/webs.
