Some features like canyons and seamounts might look familiar while others such as hydrothermal vents and methane seeps are unique to the deep.

Relatively little is known about life on the antarctic seafloor. For this reason scientists once assumed that life would be sparse in the deep ocean but virtually every probe has revealed that on the contrary life is abundant in the deep o. Oceanic crust is created at the mid oceanic ridges as a consequence of extrusive igneous activity and moves away carrying along overlying sediments. Thus for each segment of new ocean floor created at the ridges an equal amount of old oceanic crust is destroyed at the trenches or so called subduction zones.

For the seafloor an operational definition of deep subsurface is the region that is not bioturbated by animals. Little or no light penetrates this part of the ocean and most of the organisms that live there rely for subsistence on falling organic matter produced in the photic zone. At the deep sea trenches two plates converge with one plate sliding down under the other into the mantle where it is melted. Later theories showed that this was due to the reversing nature of earth s magnetic field.

On continents it is below a few meters not including soils.
