The discovery and study of ocean floor contours is called blank measures the vertical distance from the ocean surface to mountains valleys plains and other sea floor features a weighted line to measure the depth of the ocean floor.
The ocean floor is not all flat but has submarine ridges and deep ocean trenches known as the hadal zone.
A deep ocean trench is a deep valley along the ocean floor beneath which oceanic crust slowly sinks toward the mantle what is a furrow in the ground or ocean floor.

The deep sea or deep layer is the lowest layer in the ocean existing below the thermocline and above the seabed at a depth of 1000 fathoms 1800 m or more.

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 for this reason scientists once assumed that life would be sparse.
Features rising up from the ocean floor include seamounts volcanic islands and the mid oceanic ridges and rises.
But despite their name these plains are not uniformly flat.
The hadal zone also known as the hadopelagic zone and trench zone is the name given to the deepest parts of the ocean.
The deep sea floor is called the abyssal plain and is usually about 4 000 metres 13 000 ft deep.
Sunlight does not penetrate to the sea floor making these deep dark ecosystems less productive than those along the continental shelf.
