Features of the ocean floor include the continental shelf and slope, abyssal plain
What are the four main features of a typical ocean floor?
Features of the ocean include the continental shelf, slope, and rise . The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.

What can you find on the ocean floor?

Who owns the ocean floor?
The oceans have no apparent surface features — just a flat, vast, briny expanse. They’re also all connected; the world’s five oceans are technically one single ocean that covers 71 percent of the planet [source: NOAA]. This makes it difficult to divide, and so ultimately, you own the oceans .

Can a human swim to the bottom of the ocean?
The deepest point ever reached by man is 35,858 feet below the surface of the ocean, which happens to be as deep as water gets on earth. To go deeper, you’ll have to travel to the bottom of the Challenger Deep , a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam.
