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.Know More
Sheet erosion moves soil from raindrop splashes and runoff water. This occurs evenly and over a gradual slope. Rill erosion concentrates in a small dip in the landscape and causes a well-defined channel. Gully erosion expands a rill over time to form a large rift in land. Bank erosion occurs due to the natural flow of streams and rivers.
Streams and rivers erode land in three ways based on the water's velocity. They erode soil by carrying sediment away from their original locations, dissolving ions in hard sediments and striking bedrock with fast-moving particles. Hydraulic action of the water picks up small particles and carries them downstream. These fast-moving particles gradually chip away at bedrock, causing even more erosion.
The process of water erosion in the United States moves 4 billion tons of soil every year. One rainstorm can wash away 5 tons of soil per acre. As much as $20 billion is spent annually to replace soil nutrients lost due to erosion.Learn more about Erosion & Weathering
The three major types of erosion are the transporting of soil or rocks by moving water, wind or ice. Water is the primary force behind erosion. The waves of the ocean, movement of a river and falling of rain are all ways water transports materials from one location to another.Full Answer >
The major agent responsible for erosion on the Earth's surface is water. Flowing water as a result of rain, melting glaciers, moving streams and rivers erodes surfaces by displacing bits of soil and rocks, which is then moved from its original location to another. Erosion from water can result in valleys and rivers being widened and can even create new canyons over time.Full Answer >
Erosion is caused by water, wind and ice. All types of rock and soil are affected by erosion. It is a natural process, although it can be influenced by the actions of people.Full Answer >
The four agents of erosion are water, ice, wind and waves. Each of these agents is able to weather rocks, causing them to break apart after being worn down. Of the four agents of erosion, water is considered to be the most important and commonly occurring.Full Answer >
