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. NextReset

Answer 1

salinity decreases because the stream adds freshwater, though if you continue further into the ocean the salinity will remain the same, while close to the river meeting the ocean the salinity will be at a different level.

Answer 2

Salinity decreases because the stream adds fresh water to the ocean.

Step-by-step explanation:

Fresh water is called the water of rivers, lakes and most underground water, with a salinity close to zero, as opposed to sea water (which generally has a salinity close to 35 grams of dissolved salts per liter). In this case, we can say that if fresh water were added to sea water, the salinity of that water will be diluted and consequently decrease.

For this reason, we can say that the correct answer to your question is "Salinity decreases because the stream adds freshwater to the ocean."
