The continental shelf is basically an extension of a continent into an ocean. It is underwater during interglacial periods (such as today) but dry during glacial periods. The continental slope is the sloping area between the continental shelf and the continental rise (where the continental plate meets the oceanic plate). The continental shelf and the continental slope together are called the continental margin. The continental rise is located at the bottom of the continental slope and is formed by the accumulation of sediment from the continent. Past the continental rise lies the abyssal plain which is the flat ocean floor.

The continental shelf is normally made out of continental crust, the oceanic crust begins at the base of the continental rise. However in most places the oceanic crust near the continental margins is covered by continental sediments (eroded form the continents) carried down onto the Oceanic planes by deep sea canyons running off the continental rises.
Elements combine to form chemical compounds.
Powerful turbidity currents, earthquakes, or movements on a continental slope can form a submarine canyon.

The land form that is similar to an ocean trench would be a river. This is because it is a crack in the surface filled with water.
Seamounts are mountains that rise at least 1,000 meters from the ocean floor and are below the surface of the water. Seamounts form from extinct volcanos and range in height from 1,000 to 5,000 meters.

Sediment, or debris, is washed down the continental shelf and slope and settles on the continental rise. This accumulated sediment makes the slope of the continental rise more gradual and gentle than that of the continental slope
