3. The Baltic Sea has low salinity due to a massive intake of river water.
4. As evaporation increases, the salinity of the water decreases.

Select the correct response.

4. Take a look at the following remark about Waves.

1. A wave is a continuous flow of a large amount of water in a specific direction.
2. Waves are formed as the water on the ocean’s surface rises and falls alternately.
3. Waves are the energy that flows across the ocean surface, not the water itself.
