Flat features of the deep ocean floor.

Many ocean floor features are a result of the interactions that occur at the edges of these plates. An abyssal plain is an underwater plain on the deep ocean floor usually found at depths between 3 000 metres 9 800 ft and 6 000 metres 20 000 ft lying generally between the foot of a continental rise and a mid ocean ridge abyssal plains cover more than 50 of the earth s surface. The shifting plates may collide converge move away diverge or slide past transform each other. What was discovered was a large chain of mountains along the deep seafloor called mid ocean ridges.

They are among the flattest smoothest and least explored regions on earth. Finally large flat areas called abyssal plains we. Even scientist were amazed that the seafloor was not completely flat. Running through all the world s oceans is a continuous mountain range called the mid ocean ridge submarine ridge in figure 14 23.

As plates converge one plate may move under the other causing earthquakes forming volcanoes or creating deep ocean trenches. Lying along the top of the abyssal plain is the abyssal zone whose lower boundary lies at about 6 000 m 20 000 ft.
