Unit 8.E.1.1 and 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

An automotive repair shop located at point J dumps used oil into a stream behind the shop. Should residents at point K be concerned?

• No. Point K is not directly south of point J.

• Yes. All of North Carolina's streams are connected.

• No. The two areas are too far apart.

• Yes. They are located in the same river basin.
