Ocean Floor Quiz

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.
