While Abbysal plain is a beneath the surface of the water plain on the deep ocean floor, typically found at depths approximately 3,000 meters and 6,000 meters. It is in a horizontal position largely between in a mid-ocean ridge and a foot of a continental rise. Almost 50% of the Earth’s surface was sheltered by Abbysal Plains.
