2. What is the salinity range?Variable, from hypersaline to brackish, influenced by evaporation, precipitation, and freshwater inflow
3. How do marine lakes form?They form when the coast sinks, barrier islands or spits grow, or coral reefs build, trapping ocean water in a basin.
4. Why are marine lakes special for scientists?Because the water is salty yet the lake is isolated, the animals inside can evolve into new species. Scientists study these changes to learn how evolution works.
