Answer: Ocean water can cause lagoons to increase in size.
Step-by-step explanation:
Lagoons are bodies of water that are separated from the ocean by a barrier, such as a sandbar, reef, or barrier island. They are often fed by fresh water sources, such as rivers or streams, and can be affected by the tides and other oceanic influences. When ocean water enters a lagoon, it can cause the lagoon to increase in size. This is because the ocean water carries a higher salt content than the fresh water in the lagoon, and this saltwater can mix with the lagoon water, causing the overall water volume to increase. This increase in water volume can also change the water chemistry and salinity of the lagoon, which can have an impact on the plants and animals that live there. In summary, ocean water can affect lagoons by increasing their size and changing their water chemistry.
