Describe the main features of a mirror meander. Explain, by referring to river processes, how such features have been formed. You may draw a labelled diagram as part of your answer.
There are 3 courses in a river upper middle and lower. In the upper course of a river the water flows extremely fast. This is due to the upper course is often on mountainous areas. Therefore the water is very powerful enough to pick up large pebbles and rocks, which collide in a process called attrition. Along the process the bedrocks which the river flows over gets eroded by the broken fragments of rocks. In the upper course of a river vertical erosion cuts downwards through the rocks. This exposes rocks to weather such as freeze thaw action which breaks down the rocks into smaller particles.
