Erosion by friction, also known as ABRASION, is the process of wearing away a surface due to the rubbing of two objects against each other. This type of erosion is caused by the movement of sediment particles over a surface, which can be caused by wind, water, or ice. ABRASION is a common form of erosion that can occur in both natural and man-made environments. It is especially common in areas with high levels of wind and water, such as deserts and coastal regions.
