Document Summary
The scientific study of the physics, chemistry, biology, and geology of the ocean. The ocean covers most of the earth"s surface. The oceans contain 97. 5% of the earth"s surface water and are home to at least 250 000 species. There are underwater volcanoes, canyons, and trenches. Marianas trench is deeper than everest is tall. Reveals that gently sloping continental shelves underline the shallow waters bordering the continents. Shelves vary in width from 100m to 1300 km. The gentling slope that connects the continental shelf to the abyssal plane. The flat bottom of the deep ocean. Water is salty because ocean basins are the final repositories of water that runs off land. Salinity varies because of differences in evaporation, precipitation, and freshwater runoff from land and glaciers. Water also contains nutrients and dissolved gas (like oxygen) Ocean water is layered from top to bottom. Water is warmest at the surface and gets colder with depth.
