Due to erosion on the outside of a bend and deposition on the inside, the shape of a meander will change over a period of time. Erosion narrows the neck of the land within the meander and as the process continues, the meanders move closer together.
The continuous process in which hot, molten material coming to the surface of the Earth from the interior forms igneous rocks, which are then broken down by weathering to create soil and sedimentary rocks.
