Tectonic Basins Quiz

What process primarily forms rift basins?

• Subduction of oceanic crust

• Continental crust being pulled apart

• Collision of continental plates

• Sediment deposition by rivers

Which type of sedimentary record is typically found in rift basins?

• Marine sediments only

• A mix of continental and shallow marine sediments

• Deep marine sediments

• Glacial deposits

Foreland basins are primarily formed by:

• The stretching of the continental crust

• The filling of an oceanic trench

• The loading of the crust by mountain building

• The splitting of a continent into two

What type of sedimentary record is characteristic of foreland basins?

• Deep marine sediments

• Fluvial and deltaic deposits

• Thick sequences of clastic sediments

• Limestone and chalk

Pull-apart basins are formed due to:

• The collision of two continental plates

• The divergence of two oceanic plates

• Lateral movement along strike-slip faults

• The subduction of an oceanic plate beneath a continental plate

Which sedimentary records are most commonly found in pull-apart basins?

• Volcanic rocks

• Marine evaporites

• Alluvial and lacustrine deposits

• Coral reefs

Intracontinental basins are typically formed by:

• The stretching of continental lithosphere

• The folding of sedimentary layers

• Meteorite impacts

• Glacial retreat

What is a common feature of the sedimentary record in intracontinental basins?

• Deep-sea turbidites

• Extensive coal beds

• Large salt deposits

• Thick sequences of red beds

Passive margin basins form as a result of:

• The collision between oceanic and continental plates

• The rifting and subsequent drifting of continental plates

• The folding of the Earth's crust

• The deposition of sediments by large river systems

Which of the following best describes the sedimentary record found in passive margin basins?

• Predominantly volcanic materials

• Thick sequences of marine sediments

• Primarily terrestrial plant fossils

• Large deposits of metallic ores
