 So let's put the turbidity currents and turbidites together into a process. So what we have is we have a submarine slope here, one of our water level is up here. So this is an ocean, or it could be a lake. And the turbidites are first triggered by a submarine landslide. I'm just going to use submarine instead of lake. We'll call it end of slope failure. So this slope failure can be triggered by any number of things like an earthquake, a storm, a flood from a river that brings out lots of sediment and steepens the slope too much, tsunamis, all sorts of different things. So what happens in this component here, once you have the landslide, you get mixing of sediment and water to form a slurry that's denser than the surrounding water. And that forms the actual turbidity current. So because it's denser than water, it will flow down slope. So the third component is that the turbidity current, which is that slurry, flows down the slope. And this is the point where it can actually be erosional and help create those canyons. So it often erodes more sediment as it goes down. So it keeps flowing down, and at some point it starts slowing down. And that's in large part because the slope decreases. So the friction within the flow among the sediment grains and with the bottom slows the flow down. And when it starts flowing down enough, it starts depositing some sediment. Okay, so it's still flowing down, but maybe it's getting slower and less turbulent. And then sort of at this point, you start accumulating sediment. So we have these five steps more or less that reflect the stages of a turbidity current. And we can also look at what happens on the seafloor. So there are two things that are changing. I described the changes down slope, but then you also have changes through time, which are reflected vertically by the deposition of the sediment. So the changes through time are what we would see vertically if we're looking at a sequence of rock. The changes down slope would be what would happen if we could walk a set of beds laterally all representing the same time. So if we look at any given spot in time, so let's say we look right here and we can look at the flow speed as a function of time. So from A to B. So before the turbidite actually happens, the flow speed is zero. So this is where A is. And then the flow speed is suddenly very, very high. And then the turbidite passes and the front of the turbidite is moving the fastest. And then there's water being pulled around behind it as well. So it slows down through time. So maybe it has this peak flow for a little while, and then it slows down through time and goes back to essentially zero. Okay, so in any given spot, the flow speed slows down through time. So we can look at what we would predict with the flow speed. And I mentioned before that you have erosion. And so this sudden increase in flow speed often causes erosion. And then this time when the flow speed is slowing down through time, you get deposition. And then when you get out, and this would be deposition of the turbidite, and then when you go back to a flow speed of zero again, you get the mud. It's just the background sediment in the ocean settling out, and you get the mud accumulation. So at any given point, what you can see is this history of the flow speed recorded in the actual rock. Thanks for watching.
