The Sea Floor
The Deep Sea Floor, also known as the abyss floor or abyssal plains, is very flat. Along the sea floor are ridges; long, continuous depressions that follow the crest. The Mid-Atlantic Ridge is one such sea ridge.
Along the sea floor are basaltic seafloor volcanoes known as seamounts; these volcanoes are not tall enough to reach the ocean’s surface
Is the sea floor a motionless piece of land? NO! The floor of the ocean moves in a pattern known as seafloor spreading, where the crust separates in opposite directions from a central line. At this line along the mantle, magma pushes up to form a new crust, which is some of the newest rock in existence on the surface (well...under the ocean, but you get my drift). Don't take my word for it? Just ask Bill Nye! https://www.youtube.com/watch?v=GyMLlLxbfa4
There are also underwater features known as Guyots, undersea volcanoes whose apex appears to have been shorn off, flat
