Where do turbidity currents generally form?
Turbidites are deposited in the deep ocean troughs below the continental shelf, or similar structures in deep lakes, by underwater turbidity currents (or “underwater avalanches”) which slide down the steep slopes of the continental shelf edge, as illustrated in the diagram.
What kind of sedimentary deposits do turbidity currents create?
Figure 5.8. Turbidity flows are essentially underwater landslides or density-driven currents. Sediments laden with sediment are heavier than clear seawater. A deep-sea fan is a fan- or delta-shaped sedimentary deposit found along the base of the continental slopes, commonly at the mouth of submarine canyons.
What effect do turbidity currents have on the continental slope?
What effect do turbidity currents have on the continental slope? turbidity currents are erosive to the continental slope and, as a result, carve out submarine canyons.
What does the turbid and flow refer indirectly?
You know, those bummer dramas where everyone ends up dead or miserable. So, it’s probably not that surprising that the ocean makes him think of “the turbid ebb and flow of human misery.” “Turbid” means “cloudy, stirred up, muddy and murky” and it’s often used to refer to water.
What exactly is a turbidity current?
A turbidity current is a rapid, downhill flow of water caused by increased density due to high amounts of sediment. Turbidity currents can be set into motion when mud and sand on the continental shelf are loosened by earthquakes, collapsing slopes, and other geological disturbances.
Which sedimentary structure is formed by turbidity currents quizlet?
Turbidity currents are highly erosive and are thought to be responsible for the creation of deep-sea trenches.
What can create a turbidity current?
Turbidity currents can be caused by earthquakes, collapsing slopes, and other geological disturbances. Once set in motion, the turbid water rushes downward and can change the physical shape of the seafloor. The turbid water then rushes downward like an avalanche, picking up sediment and increasing in speed as it flows.
Which of the following describes the term turbidity quizlet?
Turbidity is the measure of the relative clarity of a liquid.
How are turbidity currents formed?
Turbidity currents can be set into motion when mud and sand on the continental shelf are loosened by earthquakes, collapsing slopes, and other geological disturbances. The turbid water then rushes downward like an avalanche, picking up sediment and increasing in speed as it flows.
