Geology

Deep-sea Structure
There are typical structural features that enable the ocean world to be divided into zones. Topographical zones, relating to the sea floor, and Bathymetric zones, relating to water depth.
Deep-sea Structure
Plate tectonics
The earth's crust is constantly changing, and plate material is always being created and destroyed. As a result, the continents and oceans cannot ride atop the plates without being changed.

Seamounts
Seamounts are undersea mountains. They rise steeply from the sea floor and peak below sea level. Seamounts are found in all the world's oceans. By definition, they have an elevation of more than 1000 m. They may have very steep slopes with a gradient angle of up to 60° and their summit surface area is relatively small. Seamounts are usually relatively resistant to forces of erosion because they are generally formed in volcanic processes, and therefore mainly consist of hard substrates.
