Mid oceanic ridges a mid oceanic ridge is composed of two chains of mountains separated by a large depression.

These relief features found on the ocean floor are called submarine relief. This video examines the different types of features in the ocean primarily on the ocean floor.

Oceanic land forms submarine relief there are mountains basins plateaus ridges canyons and trenches beneath the ocean water too.

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. The under water topography maps have been developed by the study of ocean floor topography. Part of byju s ncert geography notes for upsc 2019. In all about 7 5 of the total area of the oceans is covered by the continental shelves.

A number of major features of the basins depart. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.
