List three features commonly found in continental margins.
Deep oceanic trenches, volcanic arcs, high seismic activity
Continental shelves, gentle slopes, thick sediment accumulation formed from turbidity currents.
Extensive coral reefs, tropical climate, high biodiversity
What geological process is responsible for the formation of continental margins?
Plate tectonics
Volcanic eruptions
Glacial erosion
Sediment deposition
How do continental shelves differ from continental slopes?
Continental shelves are deeper than continental slopes.
Continental shelves are not connected to continents, unlike continental slopes.
Continental shelves are shallow and gently sloping, while continental slopes are steeper and more abrupt.
Continental shelves have a steeper slope than continental slopes.
How do sediment deposits contribute to the shaping of continental margins?
Sediment deposits cause continental margins to erode faster
Sediment deposits have no impact on continental margins
Sediment deposits lead to the expansion of continental margins
Sediment deposits contribute to the shaping of continental margins by accumulating and forming various features.
