What is soil creep?

Soil creep defines the slow mass wasting process of soil on a slope, under the influence of gravity (Source: Glossary of Soil Science terms, Soil Science Society of America).

How can landslides be prevented?

There are also various direct methods of preventing landslides; these include modifying slope geometry, using chemical agents to reinforce slope material, installing structures such as piles and retaining walls, grouting rock joints and fissures, diverting debris pathways, and rerouting surface and underwater drainage.

Can creep be prevented?

Control of the grain size and structure is also an effective method of reducing creep. Increasing the grain size by thermomechanical processes reduces the creep rate and extends the stress rupture life of metals by lowering the amount of grain boundary sliding.

How can we reduce erosion?

How can we stop land slippage?

The most effective, natural way to control soil erosion on slopes is to plant vegetation. Not only will vegetation help to slow down raindrops as they fall, the roots of the plants will also help to hold the soil together, making it harder for water to wash it away.

How can we prevent soil erosion Class 10 Brainly?

Answer. Explanation: The four most common soil erosion prevention methods are vegetation, geotextiles, mulch, and retaining walls. Preventing soil erosion is critical in protecting your property and exposed soil, whether from wind, weather, running water, and even the after-affects of forest fire.

How can we prevent soil erosion Class 9?

Answer: Preventive methods of soil erosion (i) Afforestation Planting more trees reduces soil erosion. (ii) Contour Ploughing Ploughing land in furrows across the natural slope of the land helps trap water and prevent the washing away of top soil along with it.

What causes soil creep landslide?

The slowest kind of landslide is known as creep. When clay in the soil on a hillside absorbs water, it will expand, causing the soil to swell. As the clay dries and contracts, the particles settle slightly in the downhill direction.

What is an example of a soil creep?

One example of soil creep in real life is from the wealthy Caribbean nation of Trinidad and Tabogo. In this country, in 2012, expensive road repair plans (estimated at about 61 million dollars!) were announced. The area surrounding the road which needed repairs was subject to soil creep.

What is soil creep and what factors facilitate it?

Creep can be facilitated by freezing and thawing because, as shown in Figure 15.12, particles are lifted perpendicular to the surface by the growth of ice crystals within the soil, and then let down vertically by gravity when the ice melts. The same effect can be produced by frequent wetting and drying of the soil.

How can soil creep impact human activities and structures?

Buildings and infrastructure located on soil creep can show cracks, curved walls, etc. Over time, these can worsen, affecting the structural stability and, therefore, the functionality of buildings and infrastructure.

What are two indicators of soil creep?

Creep is indicated by curved tree trunks, bent fences or retaining walls, tilted poles or fences, and small soil ripples or ridges.

How can farmers reduce soil erosion?

The key to reducing erosion is to keep the soil covered as much as possible (either through crop residues or permanent vegetation). Some common soil-saving practices include the following. Crop rotations using high residue crops (corn, hay, and small grain) produce large amounts of residue that help control erosion.

Which practice helps reduce soil erosion?

Crop Rotation: Rotating in high-residue crops — such as corn, hay, and small grain — can reduce erosion as the layer of residue protects topsoil from being carried away by wind and water. Conservation Tillage: Conventional tillage produces a smooth surface that leaves soil vulnerable to erosion.

What are the methods of preventing soil erosion Class 9 Brainly?

• The various methods for preventing or reducing soil erosion are:
• i. By preventing over grazing.
• ii. By planting more and more trees, as the roots of the trees hold the soil in place.

How can soil creep be identified?

Downhill creep, also known as soil creep or commonly just creep, is a type of creep characterized by the slow, downward progression of rock and soil down a low grade slope; it can also refer to slow deformation of such materials as a result of prolonged pressure and stress.

Where is soil creep most common?

Soil Creep

It is most common in damp soils where water acts as a lubricant. This allows soil particles to move over each other and the underlying rock. Eventually, the movement of soil tilts fences, posts and even trees. Soil accumulates behind walls and other obstacles and also at the foot of slopes.

What are the activities that destroy soil?

Explanation: Soil erosion is the main activity to destroy the soil that is, it occurs naturally by wind or harsh climatic conditions human activities include overgrazing , overcropping, and deforestation. Overgrazing occurs when farmers stock too man animals sheep cattle or goats on their land.

Which of the following human activities helps reduce the effect of soil erosion?

Farming techniques such as contour ploughing, stubble planting and time of ploughing can also be useful methods of soil conservation. Contour ploughing is the ploughing of the land following the natural contours of the land instead of the usual practice of going up and down the slopes in lines.

Where has soil creep occur?

creep, in geology, slow downslope movement of particles that occurs on every slope covered with loose, weathered material. Even soil covered with close-knit sod creeps downslope, as indicated by slow but persistent tilting of trees, poles, gravestones, and other objects set into the ground on hillsides.

How does soil creep occur geography?

Soil creep is a very slow movement, occurring on very gentle slopes because of the way soil particles repeatedly expand and contract in wet and dry periods. When wet, soil particles increase in size and weight, and expand at right angles. When the soil dries out, it contracts vertically.

What is slump and creep?

Creeps and slumps are very similar. They are both a form of mass wasting and have the same causes. The difference between a creep and a slump is that a creep moves slowly and gradually while a slump is faster and causes more drastic changes in terrain.

What can humans do to prevent mass movement?

Mass movements can sometimes be avoided by employing engineering techniques to make the slope more stable. Among them are: Steep slopes can be covered or sprayed with concrete covered or with a wire mesh to prevent rock falls. Retaining walls could be built to stabilize a slope.
