Oceanic basin - Wikipedia
A continental margin is the outer edge of continental crust abutting oceanic crust under coastal waters. It is one of the three major zones of the ocean floor, the other two being deep-ocean basins and mid-ocean ridges. The continental margin consists of three different features: the continental rise, the continental … See more The continental shelf is the portion of the continental margin that transitions from the shore out towards to ocean. Continental shelves are believed to make up 7% of the sea floor. The width of continental shelves worldwide varies in … See more There are two types of continental margins: active and passive margins. Active margins are typically associated with lithospheric plate boundaries. These active margins can be See more The continental shelf is the most economically valuable part of the ocean. It often is the most productive portion of the continental margin, as well as the most studied portion, due … See more As continental crust weathers and erodes, it degrades into mainly sands and clays. Many of these particles end up in streams and rivers that then … See more • Continent-ocean boundary • Convergent boundary • Passive margin See more • Map showing the locations of active and passive continental margins and the eight ocean regions See more WebView 0.2 Ocean Dimensions and Basins - ATOC 215.pdf from ATOC 215 at McGill University. - ATOC 215 Winter term 2024 Short review of material from previous courses … highback backrest support
