A science that draws on the methods and knowledge of geology, chemistry, physics, and biology to study all aspects of the ocean
The measurement of ocean depths and the charting of the shape or topography of the ocean floor.
A device that determines the distance of an object under water by recording echoes of sound waves.stands for sound navigation and range
a small underwater craft used for deep-sea research
a boundary between a continent and adjacent ocean basin floor
A gently sloping, shallow area of the ocean floor that extends outward from the edge of a continent
A steep incline leading down from the edge of the continental shelf
deep, steep-sided valleys cut into the continental slope
dense current that carries large amounts of sediment down the continental crust
Found in regions where trenches are absent. Where the continental slope merges into a more gradual incline. Has turbidity currents that follow submarine canyons deposit sediment that forms deep-sea fans.
ocean basin floor
area of the deep-ocean floor between the continental margin and the oceanic ridge
Are deep and incredibly flat features in fact these regions are likely the most level places on Earth.
An underwater volcanic peak rising from the ocean floor and having a peaked or flat-topped summit below the surface of the sea.
An underwater mountain chain where new ocean floor is formed
The process that creates new sea floor as plates move away from each other at the mid-ocean ridges
land; mineral grades eroded from continental rock and transported to the ocean
seafloor sediment of biological origin, such as sea shells and skeletons of marine life
Ooze composed mostly of the hard remains of organisms containing calcium carbonate.
biogenous sediment composed of the silica based shells of single-celled animals and algae
