GENERAL GEOLOGY

Detailed explanation-1: -Oxbow lakes-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.

Detailed explanation-2: -The lateral erosion on the outside bend causes undercutting of the river bank to form a river cliff . There is less water on the inside bend of a meander so friction causes the water to slow down, lose energy and deposit the material the river is carrying, creating a gentle slope.

Detailed explanation-3: -Over time, this means that erosion occurs on the outside of meander bends and deposition occurs on the inside. This process can lead to formation of one of Geography’s classic landforms, Ox bow lakes.

Detailed explanation-4: -The force of the water erodes and undercuts the river bank on the outside of the bend where water flow has most energy due to decreased friction. This will form a river cliff. On the inside of the bend, where the river flow is slower, material is deposited, as there is more friction. This will form a slip-off slope .

Detailed explanation-5: -The water moves faster on the outside of the bend and slower on the inside of the bend.
