Question

What are some of the physical features that are found in ocean basins?

Answer 1

The four main ocean basins are those of the Pacific, Atlantic, Indian, and Arctic Oceans. The Pacific Ocean, which occupies about one-third of Earth's surface, has the largest basin.

A number of major features of the basins depart from this average—for example, the mountainous ocean ridges, deep-sea trenches, and jagged, linear fracture zones. Other significant features of the ocean floor include aseismic ridges, abyssal hills, and seamounts and guyots.
