Question

A freshwater stream flows into the ocean, as shown in the diagram. Which statement correctly describes how the stream affects the salinity of the ocean?
Salinity increases because the stream adds salt to the ocean.
Salinity decreases because the stream adds freshwater to the ocean.
Salinity increases because the stream adds freshwater to the ocean.
Salinity remains the same because the steam adds freshwater to the ocean.

Answer 1

The answer is salinity decreases because the stream adds freshwater to the ocean. Salinity is the amount of salt that is present in the bodies of water. A stream is not salty that affects the salinity level in oceans. Water from streams will decrease to the salinity of ocean water because it does not contain much salt compared to other bodies of water.
