Introduction

The ocean floor provides significant information about the geological processes that shaped the earth's surface.

15 words

Main Body

For example, ocean studies have shown that oceanic crust is made of SIMA (Silicon and magnesium)

Made up of molten rock

Features of Ocean FloorHas sand
Has polymetallic nodules
Has volcanoes

Eg.: Mauna Kea in Hawaii

SIGNIFICANCE :-

Ocean floor is formed by seafloor spreading.
Eg.: Atlantic Ocean is formed due to divergence of American and Eurasian plate.
Red sea is formed due to divergence between the Arabian Plate and the African plate.
Thus, oceanography is important to study as it explains the formation of structures in ocean floor.
It also helps in deep sea mining for exploration of minerals

Thus, studying ocean floor is essential.
