How does upwelling affect coastal fisheries?
Bess [88]

Answer:

Upwelling improves the nutrient supply at coastal fisheries as the cold, nutrient-rich water replaces the warm, nutrient-poor surface water

Explanation:

The upwelling is simply the process through which the cold water rises up toward the surface, pushes and moves away the warmer water, until it gets warmer and is pushed by the colder water blow it. The cold water that rises toward the surface is nutrient-rich, while the warm surface water is nutrient-poor. By having the nutrient-rich cold water come toward the surface, the coastal fisheries have great benefit, as the more nutrients there are, the more fish there will be for them to catch.

Explanation:

(-4) + (-4) + 6+6+5 + 5 ​

= 14

Thus, the answer is 14
