8.E.1.1 & 8.E.1.2 Review

Upwelling is a process that brings cold, nutrient rich water to the ocean surface. What can occur because of this process?

• Decrease in fish populations

• increase in temperature

• Increase in Algae

• reduction in salinity

In North Carolina, the water in an estuary is shallow, which helps sunlight penetrate to the bottom. How is this beneficial?

• It helps promote the growth of plants

• It helps in the deposition of sediments

• It reduces the salinity of the water

• It decreases the nutrient content of the water
