Continental shelf – relatively flat part of a continental margin that is covered by shallow ocean water Continental slope – marks the boundary between the crust of the continent and the crust of the ocean floor.

  11. Abyssal Plains – large flat areas on the ocean floor. Seamounts and Guyots – scattered along the floor of the ocean are thousands of underwater mountains called seamounts. They are volcanic mountains that rise more than 1000 meters about the surrounding ocean floor. Flat top seamounts are called guyots. Trenches – the greatest depths found along the edges of the ocean floor Midocean ridge – mountain ranges on the ocean floor.

  12. Ocean Life Zones Intertidal zone – lies between the low and high tide lines. Hard for living things to survive. Neritic Zone – extends from the low tide line to the edge of the continental shelf. Rich in life. Open-Ocean Zone – bathyal and abyssal zones, no sunlight, plants do not grow, little food is available, most animals are small.
