A Turbid Environment

I would hate to be in an avalanch or a landslide. But you know, on land is not the only place they can occur. It can also happen in the oceans. An underwater landslide is called a turbidity current. What happens is that sediment is carried by rivers to the oceans. When the rivers hit the oceans, the water velocity slows down and deposits the sediment. It eventually builds up over time. Sometimes the weight of overlying sediment becomes so great that the underlying sediment will fail and a turbidity current, or underwater landslide, will occur. Turbidity currents will form submarine canyons. Be careful if you're big on scuba diving. Chances are few you'll get caught in one but better safe than sorry.
