\nThe statement that is NOT correct with regard to the continental shelf is “Shelves are absent close to plate boundaries”.
\n<\/section>\n
\n– Continental shelves are the extended perimeter of each continent, associated with relatively shallow water compared to the open ocean.
\n– Statement B is correct: Continental shelves receive large amounts of sediment from rivers and coastal erosion, making them highly sedimented environments.
\n– Statement C is correct: The continental shelf ends at the shelf break, where there is a relatively abrupt increase in slope leading down to the continental slope and then the abyssal plain.
\n– Statement D is correct: Due to shallow waters, sunlight penetration, and nutrient-rich upwellings, continental shelves are highly productive ecosystems supporting abundant marine life, making them important fishing areas.
\n– Statement A is incorrect: While continental shelves are often narrower or even largely absent at active plate boundaries (like convergent or transform margins, e.g., along the west coast of South America or parts of California) compared to passive margins (e.g., along the east coast of North America), they are not universally absent at all plate boundaries. Some types of plate boundaries or specific locations on active margins can still have continental shelves, although perhaps limited in width. Saying they are “absent” is too strong a generalization and therefore incorrect.
\n<\/section>\n
\nPassive continental margins are created by rifting and continental breakup, leading to wide, stable shelves. Active continental margins, associated with plate boundaries, are tectonically active and can have narrow or non-existent shelves depending on the specific geological processes occurring (like subduction, collision, or transform faulting).
