Detailed explanation-1: -Most of the organisms in the ocean exists in the shallow water over the continental shelves. Why is this true? Producers, the beginning of all food chains, can only exist where there is sunlight. Sea predators can easily catch their prey where the water is shallow.
Detailed explanation-2: -Estuaries are areas where freshwater streams or rivers merge with the ocean. This mixing of waters with such different salt concentrations creates a very interesting and unique ecosystem. Microflora like algae, and macroflora, such as seaweeds, marsh grasses, and mangrove trees (only in the tropics), can be found here.
Detailed explanation-3: -Formation of a Continental Shelf Inorganic material built up as rivers carried sediment-bits of rock, soil, and gravel-to the edges of the continents and into the ocean. These sediments gradually accumulated in layers at the edges of continents.
Detailed explanation-4: -The difference between the continental shelves and continental slopes is follows: 1) Continental shelves: The areas which is used to border the continental land is called continental shelves. Continental slopes: The slope which is between the continental shelves and the ocean floor is called continental slopes.
