Seas are found on the margins of the                     ocean and are partially enclosed by land.

                                                                                                                                                         

           

                               Beach: An expanse of sand and peddles along a shore.

        Lagoon: Lagoons are shallow coastal bodies of water near a sea or ocean, which got separated                         from a larger body of water by some barrier or reefs.

                Lake: A body of fresh or salt water of considerable size, surrounded by land.
