Question

1. normal trade winds push warm surface water away from the coast of south america. this water is replaced by other sea water in a process called upwelling. upwelling results in:

a. higher than normal tides.

b. fewer fish to be caught by fishermen.

c. cold and nutrient - rich water along the coastline.

d. more rain along the coast.

Explanation:

• Option A: Tides are mainly caused by gravitational forces of the moon and sun, not upwelling. So A is incorrect.
• Option B: Upwelling brings nutrients to the surface, which increases fish populations, so fishermen would catch more fish, not fewer. B is wrong.
• Option C: Upwelling brings deep, cold, and nutrient - rich water to the surface along the coastline. This is a key characteristic of upwelling.
• Option D: The cold water from upwelling cools the air above, reducing evaporation and thus less rain, not more. D is incorrect.

Answer:

C. cold and nutrient - rich water along the coastline.
