Running water causes erosion through friction. Additionally, running water can carry dust, silt or sand particles, which may also work to erode a given surface. Typically, water erodes surfaces in one of four ways.Know More
The most common type of water-induced erosion is called “sheet erosion." When water causes sheet erosion, a thin layer of substrate is removed. Sheet erosion is most common following flood events or the changing of the tides.
Rill erosion occurs when small streams of water pour down a hillside. This type of erosion takes the form of small, thin ditches that resemble a river and its tributaries. Greater erosion occurs at the bottom of hills with rills, because the water carries dirt with it, which causes the bottom of the hill to be eroded by both the water and the free sediment.
Gully erosion is caused by running water; it typically occurs as a result of the digging of a river channel. Gullies are usually so large that they do not disintegrate quickly. Erosion can also be caused by the splashing of water. Called “splash erosion”, water droplets cause the soil to fly up into the air. Sometimes, grains of sand are thrown three feet or more.Learn more about Erosion & Weathering
Waves cause erosion by moving sand and debris during storms and other events, as they break higher than normal on the beach, pulling sand back into the water with them. Human interventions and major weather events such as tropical storms and hurricanes erode beaches in this way.Full Answer >
Gravity causes erosion by pulling dirt, rocks and soil downward. For example, as water mixes with dirt to form soft mud, the mud cannot support itself against the force of gravity.Full Answer >
Acid rain causes erosion by chemically reacting with certain minerals in rock, causing it to dissolve in the water and otherwise escape the structures in which it is bonded. This is a particularly a problem with limestone and rocks derived from it, such as marble. The basic constituent of limestone is calcium carbonate, which is very vulnerable to acidic compounds.Full Answer >
Water erosion occurs when moving water carries away bits of rock and dirt. There are four types of water erosion: sheet erosion, rill erosion, gully erosion and bank erosion. All of these depend on the type of land being moved by water. This type of erosion creates valleys, canyons, shorelines and cliffs.Full Answer >
