What is the Continental Rise? The continental rise is an underwater feature found between the continental slope and the abyssal plain. This feature can be found all around the world, and it represents the final stage in the boundary between continents and the deepest part of the ocean.

Continental Margin Basic composition of continental margins, which include the continental shelf, continental slope, and continental rise. In contrast to the continental shelf, the continental slope is generally narrow in width, ranging from 6.2 to 62 miles (10 to 100 kilometers). Relatively steeper than the shelf, the slope angles down to the ocean basin at an average of 4 degrees; in some areas, the angle may be as much as 25 degrees.

- Continental crust is part of the Earth’s surface found under land masses, and oceanic crust is the surface found under the ocean floor. Oceanic crust is made of dense rock like basalt. Continental crust has rocks of lesser density like granite. Continue Reading.

- The Rocky Mountains form the Continental Divide, the mountainous ridge that runs north to south along North America and causes water to drain in separate rivers flowing to different sides of the continent. Eventually, these rivers lead to the Atlantic and Pacific Oceans as well as the Gulf of Mexico.

Continental Divide of the Americas There are other continental divides on the North American continent, however the Great Divide is by far the most prominent of these because it tends to follow a line of high peaks along the main ranges of both the American and Canadian Rocky Mountains, at a generally much higher elevation than the other divides.

Continental Divide of the Americas The Continental Divide of the Americas (also known as the Continental Gulf of Division, the Great Divide, or merely the Continental Divide) is the principal, and largely mountainous, hydrological divide of the Americas.

- The mid-Atlantic Continental Slope is a steep, narrow area paralleling the shelf and extending from the shelf break to depths of about 2,000 m (6,600 feet).The upper slope has gradients ranging from 100 feet per mile to 400 feet per mile, and is incised by numerous submarine canyons.he Continental Shelf and a portion of the current Coastal Plain were underwater 120,000 years ago, when sea levels were 20-25 feet higher. At the start of the Wisconsin glacial stage, the Laurentide ice sheet grew, trapping water on land.

Continental drift Antonio Snider-Pellegrini's Illustration of the closed and opened Atlantic Ocean (1858). Continental drift is the movement of the Earth's continents relative to each other, thus appearing to drift across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.

Continental crust Continental crust. The continental crust is the layer of igneous, sedimentary, and metamorphic rocks that forms the continents and the areas of shallow seabed close to their shores, known as continental shelves. This layer is sometimes called sial because its bulk composition is more felsic compared to the oceanic crust, called sima which has a more mafic bulk composition.

Continental Margin The continental margins along India and Antarctica are other examples of passive margins. A continental margin that has a very narrow, or even nonexistent, continental shelf and a narrow and steep continental slope is known as an active continental margin. Instead of ending in a continental rise, the continental slope of this type of margin often plunges into a deep-ocean trench, which may be filled with sediment.

Continental drift The theory of continental drift was not accepted for many years. One problem was that a plausible driving force was missing. A second problem was that Wegener's estimate of the velocity of continental motion, 250 cm/year, was implausibly high. (The currently accepted rate for the separation of the Americas from Europe and Africa is about 2.5 cm/year). And it did not help that Wegener was not a geologist.

- Menard [1964] proposed that a large shallow region (Figure 1) in the Western Pacific, which he termed the Darwin Rise, underwent major volcanism and uplift during the Cretaceous. The origin of the Darwin Rise has generally been related to mantle plumes [ Morgan, 1972].

- The transition from continental to oceanic crust commonly occurs within the outer part of the margin, called continental rise. Oceanwards beyond the edge of the rise lies the abyssal plain.arthquakes and volcanic eruptions are common on the west coast of North America, but there are no active volcanoes on the east coast and large magnitude earthquakes are rare. Geologists refer to the west coast as (tectonically) active continental margin and the east coast a passive continental margin.

Introduction to the Midcontinental Rift Crustal movement that first pulled the continent apart then reversed and began to push it back together. This compression forced the dense basaltic rocks upward, producing a range of mountains along the axis of the rift.

Continental Margin A continental margin that has a broad continental shelf, a gentle continental slope, and a pronounced continental rise is known as a passive continental margin. This type of margin experiences little, if any, volcanic or earthquake activity. The build-up of sediment is the primary activity affecting a passive margin.he continental shelf is the region that extends seaward from the shoreline to a sharp drop-off that marks the beginning of the continental slope. That drop-off is known as the continental shelf break. Continental shelves vary in width from 3 to 930 miles (5 to 1,500 kilometers).

The Continental Shelf The waters of the continental shelf are rarely more than 500 feet deep, compared to the open ocean which can be miles deep. The continental shelf extends outward to the continental slope and continental rise, where the deep ocean truly begins, ultimately leading to the abyssal plain. The figure below is a schematic diagram of the continental shelf.
