* Erosion: The faster-moving water on the outside of a meander bend has more energy and erodes the riverbank, causing the bend to become more pronounced.
* Deposition: The slower-moving water on the inside of the bend loses energy and deposits sediment, creating a point bar.
In summary:
* Erosion widens the bend and makes it more pronounced.
* Deposition builds up the inside of the bend and creates point bars.
The interplay between erosion and deposition results in the characteristic winding shape of a meandering river.
