Explanation:

Abyssal plain : very level area of the deep-ocean floor typically lying at the foot of the continental rise G

Guyot: A submerged flat-topped seamount H

Deep-ocean basin:  portion of the seafloor between the continental margin and oceanic ridge; comprises 30 percent of Earth's surface C

Continental Volcanic Arc: Mountains are formed in part by igneous activity associated with the subduction of oceanic lithosphere beneath a continent A

Deep-Ocean Trench: Long, relatively narrow crease in the seafloor that forms the deepest parts of the ocean. D

Oceanic Plateau:  extensive region of the ocean floor with thick accumulation of pillow basalts and other mafic rock E

Seamounts: An isolated volcanic peak that rises  above the deep-ocean floor

Volcanic island arc: A chain of volcanic islands generally located a few hundred kilometers from a tench where active subduction of one oceanic slab beneath another is occuring; some trenches run parallel to an arc shapes row of active volcanoes
