What was discovered was a large chain of mountains along the deep seafloor called mid ocean ridges.
Flat features of the deep ocean floor.
The shifting plates may collide converge move away diverge or slide past transform each other.
They are among the flattest smoothest and least explored regions on earth.
Scientists also discovered deep sea trenches along the edges of continents or in the sea near chains of active volcanoes.
Even scientist were amazed that the seafloor was not completely flat.
Lying along the top of the abyssal plain is the abyssal zone whose lower boundary lies at about 6 000 m 20 000 ft.
Finally large flat areas called abyssal plains we.
Deep ocean water is divided into layers or zones each with typical features of salinity pressure temperature and marine life according to their depth.
Many ocean floor features are a result of the interactions that occur at the edges of these plates.
As plates converge one plate may move under the other causing earthquakes forming volcanoes or creating deep ocean trenches.
The smooth flat regions that make up 40 of the ocean floor are the abyssal plain.
