Geological Features and Processes

The video tutorial explores ocean basins, focusing on sediment deposition and the structure of continental shelves, slopes, and rises. It discusses submarine canyons and turbidite deposits, highlighting their formation and significance. The abyssal plain's features, including mid-ocean ridges and trenches, are examined. The tutorial also covers sediment deposition patterns and how they indicate sea level changes, explaining concepts like transgression and regression.

What is the primary characteristic of ocean basins that makes them significant for sediment collection?

• They are the highest points on Earth's surface.

• They are the lowest points on Earth's surface.

• They are located near tectonic plate boundaries.

• They are covered by ice.

Which part of the ocean basin is characterized by relatively shallow water extending from the coast?

• Continental slope

• Mid-ocean ridge

• Abyssal plain

• Continental shelf

What type of crust primarily underlies the continental shelf?

• Continental crust

• Granitic crust

• Oceanic crust

• Basaltic crust

What are submarine canyons primarily associated with?

• Sediment deposition

• Volcanic eruptions

• Submarine landslides

• Tectonic uplift

What is the initial layer found at the base of a turbidite deposit?

• Mud

• Gravel

• Silt

• Sand

Which feature is commonly found at a divergent boundary on the abyssal plain?

• Submarine canyon

• Volcanic arc

• Oceanic trench

• Mid-ocean ridge

What geological feature is formed at oceanic-oceanic convergent boundaries?

• Mid-ocean ridge

• Volcanic arc

• Abyssal plain

• Continental shelf

What type of sediment is typically found closest to the shore?

• Limestone

• Silt

• Clay

• Sand

What does a sequence of rock with sand at the bottom, followed by silt, and then limestone indicate?

• Sea level is falling.

• Sea level is rising.

• Tectonic activity is decreasing.

• Sediment supply is increasing.

What term describes the process when sediment is deposited further offshore due to rising sea levels?

• Prograding

• Regression

• Erosion

• Transgression
