In which zone are turbidity currents found? What are these currents, how do they flow, and what causes

them?

  Answer is given in the explanation.

Explanation:

The turbidity is a measure of the content of particles such as sediments, plankton or organic by-products in a body of water. As the turbidity of the water increases, it becomes denser and less clear due to a higher concentration of these light-blocking particles.

Turbid currents can start when mud and sand on the continental shelf are loosened by earthquakes, collapsed slopes and other geological disturbances. Cloudy water flows in like an avalanche, collects sediment and increases speed when it flows.

Turbid currents can change the physical shape of the ocean floor by eroding large areas and creating underwater canyons. These streams also deposit large amounts of sediment wherever they flow, usually in a gradient or fan shape, with the largest particles at the bottom and the smallest particles at the top.

complete the square on the right side of the equation;

-5(x + 0)^2 + 15

answer: d. y = -x^2 + 15

we would need to see the picture to answer it
