Gully erosion is the removal of soil along drainage lines by surface water runoff. Once started, gullies will continue to move by headward erosion or by slumping of the side walls unless steps are taken to stabilise the disturbance. Related Questions. CBSE > Class 10 > Social Science.
What is gully erosion Class 8? Gully erosion occurs due to the runoff of surface water causing the removal of soil with drainage lines. Gullies when started once, will move by headward erosion or even by slumping of side walls unless and un-till proper steps will be taken in order to stabilize the disturbance.
Similarly, What is gully and sheet erosion? Gully erosion: The running water cuts through the clayey soil and makes deep channels in it. As a result of gully erosion, the land becomes unfit for cultivation. Sheet erosion: Water flows in a large quantity in the form of sheets and erodes the soil.
What is strip cropping?
Definition: Strip cropping is a method of farming used when a slope is too steep or too long, or otherwise, when one does not have an alternative method of preventing soil erosion.
How is a gully formed?
Gullies are permanent erosional forms that develop when water concentrates in narrow runoff paths and channels and cuts into the soil to depths that cannot be smoothed over by tillage any more.
What is sheet erosion 10th?
Sheet Erosion: When the vegetation cover of an area is removed, the rainwater instead of seeping into the ground washes down the slope. A complete layer is carried along with water in a larger area. It is called sheet erosion.

What is parallel cropping? Parallel cropping is an agricultural method by which two crops are grown together, in the same land in parallel rows. Both crops grown do not compete for nutrients and have no effect on each other.
What is the counter plugging?

What is shelter belt 10? A shelterbelt is defined as a barrier of trees and shrubs that provides protection from wind and storm and decreases erosion. … Livestock shelterbelts protect livestock and livestock facilities, and can provide odor control. Roadside shelterbelts may be planted for snow control along roads, and for dust reduction.
How deep is a gully?
A small gully is considered to be less than 8 feet deep, a medium gully less than 8 to 15 feet deep, and a large gully more than 15 feet deep. The drainage area—that is, the area draining into a gully at any given point—also affects the type of control that may be used.

What are gully plugs? A check dam (or also called gully plug) is a small, temporary or permanent dam constructed across a drainage ditch, swale, or channel to lower the speed of concentrated flows for a certain design range of storm events and to conserve soil moisture.
What is a splash erosion?
Splash erosion or rain drop impact represents the first stage in the erosion process. Splash erosion results from the bombardment of the soil surface by rain drops. Rain drops behave as little bombs when falling on exposed or bare soil, displacing soil particles and destroying soil structure.
What is sheet and gully erosion?
Sheet Erosion: When the vegetation cover of an area is removed, the rain, instead of sinking into the ground, washes the soil downslope. Each succeeding rain-storm washes away a thin layer of absorbed top soil. This is known as Sheet Erosion. … This type of erosion is known as Gully Erosion.
What is gully erosion Class 5? The running water cuts through the clayey soils and makes deep channels known as Gullies. This type of erosion is called gully erosion. Gully erosion can be found in the Chambal basin where it is called Ravines. Geography.
Which state of India has the best example of gully erosion?

What is sheet flood?
Sheet flooding exists in areas that are flat or have a low slope and where there are no or few well-defined washes, or where washes are not large enough to contain all of the water delivered by large storm events. As a result, flood waters flow in a broad sheet across the entire ground surface.
What are river abrasions? 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.
What is plucking in geography?
Definition: Plucking is a process of erosion that occurs during glaciation. As ice and glaciers move, they scrape along the surrounding rock and pull away pieces of rock which causes erosion. Plucking.
