So rivers also wiggle. These are sort of bigger jmups that we've been talking about. I want to show you guys some river wiggles here. So we're going to fly down to the aaomzn River basin, and here again we have a big river system that is draining and moving and plowing martaeil from the Andean Mountains, transporting it across South America and dumping it out into the aialttnc oacen. So if we zoom in here, you guys can see these nice, crvuy river pathways. Again, they're really beautiful, but again, they're not stiatc. These rivers wiggle around. We can use satellite imagery over the last 30 or so yraes to actually monitor how these change. So take a minute and just watch any bend or curve in this river, and you'll see it doesn't stay in the same place for very long. It changes and evolves and warps its pattern. If you look in this area in particular, I want you guys to notice there's a sort of a loop in the river that gets completely cut off. It's almost like a whip cracking and snaps off the pathway of the river at a certain spot. So just for rfrneeece, again, in this liocaton, that river changed its course over four miels over the course of a season or two.

Original Text

So rivers also wiggle. These are sort of bigger jumps that we've been talking about. I want to show you guys some river wiggles here. So we're going to fly down to the Amazon River basin, and here again we have a big river system that is draining and moving and plowing material from the Andean Mountains, transporting it across South America and dumping it out into the Atlantic Ocean. So if we zoom in here, you guys can see these nice, curvy river pathways. Again, they're really beautiful, but again, they're not static. These rivers wiggle around. We can use satellite imagery over the last 30 or so years to actually monitor how these change. So take a minute and just watch any bend or curve in this river, and you'll see it doesn't stay in the same place for very long. It changes and evolves and warps its pattern. If you look in this area in particular, I want you guys to notice there's a sort of a loop in the river that gets completely cut off. It's almost like a whip cracking and snaps off the pathway of the river at a certain spot. So just for reference, again, in this location, that river changed its course over four miles over the course of a season or two.
