The ocean floor may be segmented into how many divisions based on the depth as well as the forms of relief?

Explanation

The ocean floor may be segmented into three major divisions based on the depth as well as the forms of relief. These divisions are:(i) Continental margins, (ii) Abyssal plains and (iii) Mid-oceanic ridges.
(i) Continental margins
(a) Form transitional zone between continental shore and deep sea basins
(b) They include continental slope, shelf, continental rise and deep oceanic trenches
(ii) Abyssal plains
(a) Extensive plains
(b) Found between continental margin and mid oceanic ridge
(c) Continental sediments get deposited
(iii) Mid-oceanic ridges
(a) Distribution of volcanoes and earthquakes
(b) All volcanoes and earthquakes are parallel to the coast
(c) This line also co-incides with mid- Atlantic ridge and Alpine Himalayan system
(d) Around the Pacific Ocean it is called ring of fire mid oceanic ridges.
