Question

the california current is an ocean current that moves cold water from the north along the west coast of the united states. the main effect of this current is to make the climate of the west coast ______. a. dryer b. wetter c. cooler d. warmer

Explanation:

Ocean currents affect climate. Cold ocean currents (like the California current, which carries cold water) have a cooling effect on the adjacent coastal areas. A cold current brings cold water, so it makes the west coast's climate cooler. Option A (dryer) is more related to some coastal fog effects but the main temperature - related effect here is cooling. Option B (wetter) is incorrect as cold currents generally don't bring more moisture - laden air for increased precipitation in this context. Option D (warmer) is opposite to the effect of a cold current.

Answer:

C. cooler
