Here's why:
* Turbidity currents are dense, fast-moving underwater avalanches of sediment and water. They occur when sediment is disturbed on the continental shelf (often by earthquakes or storms) and rushes down the slope.
* These currents can travel for hundreds of kilometers, carrying vast amounts of sediment far out into the deep ocean.
* As they slow down, the sediment settles out, forming thick layers of sediment on the ocean floor.
Other factors that contribute to sediment distribution:
* Ocean currents: These currents can carry finer sediments, like clay, long distances and deposit them in specific areas.
* Biological processes: Marine organisms, like plankton, contribute to the sediment by producing shells and other skeletal remains that settle to the bottom.
* Volcanic activity: Volcanic eruptions can release ash and other debris that can be transported by currents and deposited on the ocean floor.
Let me know if you'd like more details on any of these processes!
