The Ocean Floor Is

Though people have traveled on the ocean for millennia people have explored only a tiny fraction of the ocean floor.
The ocean floor is. Climate change is sinking the ocean floor at a rate around 0 1 millimeters 0 004 inches per year. Mountains plains channels canyons exposed rocks and sediment covered areas. The lack of weathering and erosion in most areas however allows geological processes to be seen more clearly on the seafloor than. The ocean floor is sometimes called the final frontier of the modern era.
We know very little about the vast expanse of our oceans. Bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics. The ocean floor is literally the floor of the ocean. The outer rocky layer of the earth includes about a dozen large sections called tectonic plates that are arranged like a spherical jig saw puzzle floating on top of the earth s hot flowing mantle.
Not too many people have gone to the floor of the ocean as it requires special diving equipment. The ocean basins are characterized not only by lying in deep water the ocean floor averages about 4km below sea level but also by being underlain by a thin layer of crust. It is the bottom of the ocean when you dive. On average oceanic crust is only 6 to 7km thick compared to 35 to 40km for con tinental crust.
