Over time the coast generally evens out. The softer areas fill up with sediment eroded from hard areas, and rock formations are eroded away. [4] Also erosion commonly happens in areas where there are strong winds, loose sand, and soft rocks. The blowing of millions of sharp sand grains creates a sandblasting effect. This effect helps to erode ...
On such hard rock, the erosion took the form of deep, narrow cuts. The erosion work continues even today and the water wears away the rock at a rate of two millimeters per year. The fall track therefore gradually moves back upstream towards the mountain as part of the headward erosion. As a result, the eddies also move deeper into the channel.
A topographic map of Coyote Natural Bridge in Utah shows how the meandering Coyote Gulch carved a shorter route through the rock under the arch. The old riverbed is now higher than the present water level. Some natural bridges may look like arches, but they form in the path of streams that wear away and penetrate the rock.

Glacial abrasion is the surface wear achieved by individual clasts, or rocks of various sizes, contained within ice or by subglacial sediment as the glacier slides over bedrock. [9] Abrasion can crush smaller grains or particles and remove grains or multigrain fragments, but the removal of larger fragments is classified as plucking (or ...
