What are the 5 causes of erosion?
Five agents of erosion are gravity, running water, glaciers, waves, and wind.
What are the major cause of erosion?
Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. Activities that remove vegetation, disturb the ground, or allow the ground to dry are activities that increase erosion.

What are the 4 stages of erosion?
Destructive waves erode through four main processes; Hydraulic Action, Compression, Abrasion and Attrition.
What are 2 causes of soil erosion?
What Causes Erosion? Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
What are the types of soil erosion and their main causes?
- Sheet erosion by water;
- Wind erosion;
- Rill erosion – happens with heavy rains and usually creates smalls rills over hillsides;
- Gully erosion – when water runoff removes soil along drainage lines.
- Ephemeral erosion that occurs in natural depressions.
What are the 3 types of erosion?
The main forms of erosion are: surface erosion. fluvial erosion. mass-movement erosion.
What are the 4 ways that sediments can be eroded?
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 types of erosion in geography?
- hydraulic action;
- abrasion / corrasion;
- attrition; and.
- corrosion.
What are the causes and effects of erosion?
There are many causes of soil erosion, most of them being the same as other forms of erosion: namely water, ice, wind, and gravity. The effects of soil erosion can include the loss of fertile land to floods or water pollution, among others.
What are the causes of erosion in Nigeria?
From these studies, the major causes of soil erosion across Nigeria are mainly human activities, climatic factors (rainfall), inherent geology, undulating topography, and soil nature while control measures such as provision of vegetative cover, proper soil and water conservation practices, use of adequate crop …
What are the causes of soil erosion PDF?
The main causes of soil erosion are overgrazing (35 percent), deforestation (30 percent) and agricultural activities (28 percent). Overgrazing causes degradation when the soil loses it fertility and sparse vegetation cover. The major factors affecting soil erosion are: 1.
What are the 6 types of erosion?
- 1.1 Rainfall and surface runoff.
- 1.2 Rivers and streams.
- 1.3 Coastal erosion.
- 1.4 Chemical erosion.
- 1.5 Glaciers.
- 1.6 Floods.
- 1.7 Wind erosion.
- 1.8 Mass movement.
What are four features formed by wave erosion?
Lesson Summary
Wave energy produces erosional formations such as cliffs, wave cut platforms, sea arches, and sea stacks. When waves reach the shore, they can form deposits such as beaches, spits, and barrier islands.
What are the 4 stages of gully formation?
A gully develops in three distinct stages; waterfall erosion; channel erosion along the gully bed; and landslide erosion on gully banks. Correct gully control measures must be determined according to these development stages.
What are the causes of soil erosion Class 10 geography?
- Rainfall and Flooding. Higher intensity of rainstorm 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.
How does ice cause erosion?
Glaciers cause erosion in two main ways: plucking and abrasion. Plucking is caused when sediments are picked up by a glacier. They freeze to the bottom of the glacier and are carried away by the flowing ice. … The rocks and sediment grind away as the glacier moves.
How does wind cause erosion?
Wind erosion is a natural process that moves soil from one location to another by wind power. … Wind erosion can be caused by a light wind that rolls soil particles along the surface through to a strong wind that lifts a large volume of soil particles into the air to create dust storms.
What is soil erosion What are the causes and prevention?
Soil erosion is the wearing away of topsoil. It is caused by factors such as water, wind and tillage of farm fields. … One of the best ways to prevent soil erosion is to increase vegetation, which locks in the soil particles and breaks up damaging winds.
What are the examples of erosion?
- Caves. Caves are carved out over thousands of years by flowing water, but that activity can be sped up by carbonic acid present in the water. …
- River Banks. …
- Cracks in Rocks. …
- Gravitation Erosion. …
- Coastal Erosion.
What are the 5 types of water erosion?
These are inter-rill erosion, rill erosion, gully erosion, and streambank erosion.
What are 10 types of erosion?
- Surface Runoff and Rainfall Erosion.
- Sheet Erosion.
- Rill Erosion.
- Gully Erosion.
- Water Erosion.
- Tunnel Erosion.
- Bank Erosion.
- Glacial Erosion.
Which agents do cause erosion?
Water, wind, ice, and waves are the agents of erosion that wear away at the surface of the Earth.
How is sedimentation caused?
Sediment can come from soil erosion or from the decomposition of plants and animals. Wind, water and ice help carry these particles to rivers, lakes and streams. The Environmental Protection Agency lists sediment as the most common pollutant in rivers, streams, lakes and reservoirs.
What are the 10 causes of erosion?
- Water runoff and rainfall intensity. This process begins when the raindrops break down the soil making it vulnerable to movement. …
- The slope of the land. …
- Soil texture. …
- Deforestation. …
- Wind. …
- Land tillage. …
- Overgrazing. …
- Harsh climatic conditions.
What are 3 effects of erosion?
- reduced ability of the soil to store water and nutrients.
- exposure of subsoil, which often has poor physical and chemical properties.
- higher rates of runoff, shedding water and nutrients otherwise used for crop growth.
- loss of newly planted crops.
- deposits of silt in low-lying areas.
