Which of the following statements about turbidity currents is true? choose one: a. turbidity currents and river erosion carve deep submarine canyons. b. they are found only on active continental margins. c. they leave deposits of graded beds called guyots. d. they are responsible for creating the continental shelf.

Option A is correct.

Explanation:

Turbidity currents are created when sand and mud are loosened from the continental shelf by any geological disturbance such as an earthquake.

The current continues to quickly grow in size, as it picks up dirt, rocks and all sort of dirt and increasing its speed. Over time, these currents can alter the shape of the seafloor, creating large submarine canyons.
