I must be watching more science stuff these days on Youtube, because this was recommended for me. And I found it fascinating. I'd long since noticed some channels in the sea bed in various places, but this actually explains them. It turns out that in some places, there are sediment-laden undersea rivers that extend thousands of kilometers from the continental edges.
