Scientists also discovered deep sea trenches along the edges of continents or in the sea near chains of active volcanoes.
Flat features of the deep ocean floor.
Deep ocean basins deep ocean basins situated between the continen tal margins and oceanic ridges are abyssal plains parts of these regions consist of incredibly flat features deep ocean trenches ocean floor also contains extremely deep depressions seamounts dotting the ocean floor are submerged volcanic structure oceanic ridges oceanic ridge mid.
The shifting plates may collide converge move away diverge or slide past transform each other.
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.
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.
The smooth flat regions that make up 40 of the ocean floor are the abyssal plain.
Running through all the world s oceans is a continuous mountain range called the mid ocean ridge submarine ridge in figure 14 23.
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.
