Question

1pt the water in upwellings is ______.

a. cold

b. nutrient-rich

c. oxygen rich

d. all of the above

Explanation:

Upwelling brings deep - ocean water to the surface. Deep - ocean water is cold (as deep water has lower temperatures), nutrient - rich (because it has accumulated nutrients from the decomposition of organic matter in the deep), and oxygen - rich (due to the cold temperature which can hold more dissolved oxygen and the lack of extensive biological activity that consumes oxygen deeply). So the water in upwellings has all these properties.

Answer:

D. all of the above
