i went to marianas trench in the ocean. It is the deepest trench in the ocean. it is 35,000 feet. i noticed that going through the ocean the depth gets less or more because of all the hills. Going toward a continent it gets less and less due to the massive land mass.

People study the waves of the ocean so that they can predict if there is going to be a big wave that can cause major flooding. They study it and will let people know if anything will happen or let people know if they could be in any danger

90% of marine life live in the sunlit zone. the sunlit zone goes down to 600 feet. Plankton live in this lit area. The second part of the ocean is the Twilight zone which has only a little light. lantern fish, rattalk fish, jelly fish, hatchet fish, viper fish. The deepest part of the ocean is known as the midnight Zone. Ninety percent of marine life live down there. The temp is nearly freezing down there. The angler fish, tripod fish, sea cucumber, snipe eel, oppossom shrimp, and black swallower. 

Plankton is one of the smallest organisms in the sea. It is a single celled organism. Plankton is eaten by shrimp, sharks, and whales. Planktonic organisms can vary is size. From being invisible like to the naked eye. To as big as a jelly fish.
