Together they contain the overwhelming majority of all water on the planet and have an average depth of almost 4 km about 2 5 miles.
Major relief features of ocean floor.
They are uniquely flat with a gradient of less than 10 000.
Major ocean relief features four major divisions in the ocean relief are.
Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet.
These forms are called submarine relief.
The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.
It comprises of many complex and varied relief as observed on the earth s surface.
A number of major features of the basins depart.
Apart from the above mentioned major relief features of the ocean floor some minor but significant features predominate in different parts of the oceans.
The large supply of terrigenous and shallow water sediments buries the irregular topography to form a generally flat relief.
The continental shelf the continental slope the continental rise the deep sea plain or the abyssal plain.
The ocean basins are broadly divided into four major subdivisions.
The oceanic relief features are in the form of mountains basins plateaus ridges canyons and trenches beneath the ocean water.
These relief features found on the ocean floor are called submarine relief.
The ocean floor also has high mountains deep trenches and large flat plains.
Relief of the ocean floor.
Ocean relief ocean relief is largely due to tectonic volcanic erosional and depositional processes and their interactions.
Ocean relief is the outcome of the great depressions of the earth s outer layer mostly on the bottom surface.
The bottom surface of the ocean or known as land under the waters of the ocean floor creating the complex and varied features.
Ocean relief features are divided into major and minor relief features.
Mid oceanic ridges a mid oceanic ridge is composed of two chains of mountains separated by a large depression.
The ocean floors can be divided into four major divisions and some minor relief features.
Ocean basin any of several vast submarine regions that collectively cover nearly three quarters of earth s surface.
Oceanic land forms submarine relief there are mountains basins plateaus ridges canyons and trenches beneath the ocean water too.
This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.
The ocean floor is not flat as it was believed to be in the earlier days.
These features are formed due to the tectonic volcanic and depositional activities.
