Technology to study Oceans Oceanography- movement of ocean water, characteristics of the ocean floor, and the organisms that live in the ocean. Sonar- sound navigation and ranging, a system that uses acoustic signals to locate objects. Submersibles- underwater research vessels, used to study ocean depth. Underwater Research- using submersibles.

Boundary of Continental Crust & Oceanic Crust Continental Crust- shallow sea floor that is located between the shoreline and the deep- ocean bottom. Deep-Ocean Basin- part of the ocean floor that is under deep water beyond the continent margin and that is composed of oceanic crust and a thin layer of sediment.
5
Deep Basin Features Trenches- long, narrow and steep depressions that forms as a result of subduction of a tectonic plate. Abyssal Plains- a large, flat, almost level area of the deep-ocean basin. Ridges- forms underwater mountain ranges that run along the floors of all oceans.
6
Ocean Sediments Inorganic- rock particles that were carried from land by rivers. Volcanoes, glaciers, and meteorites contribute to sediment emptying. Biogenic- originally produced by living organisms. The remains of marine plants and animals create biogenic sediments. Chemical- when substances are dissolved in ocean water crystallize, they form nodules, which is formed by chemical substances.
