Quizplus · Accepted Answer

An estuary is a body of water in which freshwater from rivers mixes with salt water from the ocean, creating a unique environment with variable salinity levels. It forms when a river valley is flooded by rising sea levels. A lagoon is also a body of water near the shore, but it is typically separated from the ocean by a barrier island or coral reef. Jetty and atoll are not appropriate choices for the described scenario.
