There are four main types of water erosion: inter-rill erosion, rill erosion, gully erosion, and streambank erosion.
What are the 5 types of erosion?
The main forms of erosion are:
- surface erosion.
- fluvial erosion.
- mass-movement erosion.
- streambank erosion.
What are the 3 types of water erosion?
These particles move away from the field, and end up in streams and waterways. Three types of water erosion can occur, sheet, rill, and gully.
What are the 4 main causes of erosion?
Four Causes of Soil Erosion
- Water. Water is the most common cause of soil erosion.
- Wind. Wind can also make soil erode by displacing it.
- Ice. We don’t get much ice here in Lawrenceville, GA, but for those that do, the concept is the same as water.
- Gravity. Gravity is a primary culprit behind the three other causes.
What are the 8 types of erosion?
Soil Erosion
- Rain Drop or Splash Erosion.
- Sheet Erosion.
- Rill Erosion.
- Gully Erosion.
- Stream Bank Erosion.
What are the 7 causes of erosion?
Following are the important causes of soil erosion:
- Rainfall and Flooding. Higher intensity of rainstorms is the main cause of soil erosion.
- Agriculture. The farming practices are the major cause of soil erosion.
- Grazing.
- Logging and Mining.
- Construction.
- Rivers and Streams.
- Heavy Winds.
- Loss of Arable Land.
What causes water erosion?
Water erosion occurs when rain or snowmelt displaces the soil on the ground. The more water flowing over the land, the more soil particles are moved or transported away. Land that has no vegetation—including farm fields that are left barren after crop harvest—are especially vulnerable to water erosion.
What is example of water erosion?
Gully erosion happens when runoff concentrates and flows strongly enough to detach and move soil particles. For example, a waterfall may form, with runoff picking up energy as it plunges over the gully head. Splashback at the base of the gully head erodes the subsoil and the gully eats its way up the slope.
What is one example of water erosion?
For example, the erosion of banks from coursing rivers over hundreds of years is a natural form of water erosion that would occur with or without human interference.
What are the 3 main erosional processes?
Abrasion – When pebbles grind along the river bank and bed in a sand-papering effect. Attrition – When rocks that the river is carrying knock against each other. They break apart to become smaller and more rounded. Solution – When the water dissolves certain types of rocks, eg limestone.
What are the 4 most common agents of erosion?
Erosion is the transportation of sediment at the Earth’s surface. 4 agents move sediment: Water, Wind, Glaciers, and Mass Wasting (gravity).
What are the 4 erosional landforms?
Different landforms created on the surface of the earth because of erosion are called erosional landforms. Valleys, potholes, entrenched Meanders and river Terraces are some examples of erosional landforms.
What are 5 facts about erosion?
Erosion Facts for Kids
- Water, Wind, and Ice can cause Erosion.
- Water erosion happens when water moves rock or soil.
- Coastal Erosion is caused by waves especially during storms.
- Gravity impacts Erosion in indirect ways like landslides and mudslides.
- Wind Erosion happens mainly on dry flat land or sandy areas.
What are the 2 types of erosion?
There are two types of erosion: intrinsic and extrinsic.
What are the 6 processes of erosion?

What is erosion Class 11?
Erosion is the process in which rock particles are carried away by wind and water.
What are 5 natural causes of erosion?
Different Soil Erosion Causes
- 1) Sheet erosion by water;
- 2) Wind erosion;
- 3) Rill erosion – happens with heavy rains and usually creates smalls rills over hillsides;
- 4) Gully erosion – when water runoff removes soil along drainage lines.
- 5) Ephemeral erosion that occurs in natural depressions.
What are 5 main human causes of erosion?
These causes include road erosion, house construction, steep slope cultivation, tourism development, and animal trampling. These activities destroy surface vegetation and increase the potential for soil loss through exposed swallow holes (karst fissures).
What are the two main causes of erosion?
Basically, there are two main causes of soil erosion – wind and water. When the topmost layer of the soil is loose, it becomes vulnerable to the natural forces of wind and water to blow the soil particle away.
What are the effects of water erosion?
Water erosion, for example, results in loss of soil structure, surface crusting, waterlogging, reduction in organic matter, and breakdown of stable aggregates. In the face of such an onslaught, soil resources very quickly deteriorate. Farming becomes more difficult and more costly.
What happens in water erosion?
Water erosion is the removal of soil by water and transportation of the eroded materials away from the point of removal. Water action due to rain erodes the soil and causes activities like gully, rill, and stream erosion leading to the downstream effects of flooding and sedimentation.
