Question

A passive continental margin has a _____, while an active margin does not.

Answer 1

continental rise

Step-by-step explanation:

Two main types of continental margins have been identified: liabilities and assets. Passive margins are found along most of the coastal areas surrounding the Atlantic and Indian Ocean, including the eastern coasts of North and South America, as well as the coastal areas of Europe and Africa. Passive margins are not located along an active plate edge and, therefore, experience very little volcanism and few earthquakes. These are places where materials from weathering and erosion of adjacent land masses accumulate, which they form a thick and wide wedge of relatively unaltered sediments.

On the contrary, active continental margins appear where the oceanic lithosphere is being subducted below the edge of a continent. The result is a relatively narrow margin, consisting of very deformed sediments that were torn from the descending lithospheric plate. Active continental margins are common around the edge of the Pacific, where they are parallel to underwater pits.

Answer 2

A passive continental margin has a continental rise. It is a submerged element found between the mainland slant and the deep plain. This element can be discovered all around the globe, and it speaks to the last stage in the limit amongst landmasses and the most profound piece of the sea. The earth in the mainland rise is very exceptional, and numerous oceanographers ponder it broadly in the expectations of adopting more about the sea and geologic history.
