Erosion causes physical changes. This means the process of erosion doesn’t change the chemical composition of material, it only changes how it looks….

What does it mean to alter a landscape ” – and the answer is that it means that something is changing how the landscape looks like. For example, a river would make a valley deeper through carrying stones with the water and removing sand from the bottom of the river, and so the valley would be altered, that is changed.

What does it mean to alter a landscape? To blow dust around. To change what land looks like.

TIM: Beaches are formed by weathering and erosion, too. Sand is made by the gradual process of pebbles being broken up into smaller and smaller pieces by the motion of waves.

For heavy erosion in areas of concentrated flow, the most effective solutions are check dams or terraces.

1. Replant Vegetation Suited to Site Conditions. Well-established vegetation can stabilize the soil in cases of light erosion.
2. Footpaths with Exposed Soil: Cover with Mulch or Gravel.
3. Terraces.
4. Build Check Dams.

Erosion occurs when natural forces alter the landscape. What does it mean to alter a landscape? You just studied 10 terms!

The action of erosion can create an array of coastal landscape features. For example, erosion can bore holes that form caves. When water breaks through the back of the cave, it can create an arch. The continual pounding of waves can cause the top of the arch to fall, leaving nothing but rock columns called sea stacks.

Erosion is another geological process that creates landforms. When mechanical and chemical weathering breaks up materials on the Earth’s surface, erosion can move them to new locations. For example, wind, water or ice can create a valley by removing material. Plateaus can also be formed this way.

Aside from desertification, there is no doubt that human activities are a major cause of soil erosion in general. Construction of roads and buildings, logging, mining, and agricultural production have resulted in large amounts of soil erosion in the U.S. and around the world.

How Do Humans Cause Erosion?

• Deforestation. Deforestation, which is logging or burning forests, is a way in which humans cause erosion.
• Watering. Watering gardens and lawns also causes erosion.
• Agriculture. Agriculture is the main way humans cause soil 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.

How to prevent 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.

Five Ways To Stop Erosion On A Hillside

1. 1) Build A Garden Terrace. Preventing soil erosion on a hillside is a steep challenge.
2. 3) Use Sandbags As Diversions. You can’t necessarily fight nature, but you can certainly try to channel and divert it.
3. 5) Use Geotextiles Or Erosion Control Blankets.

Techniques for steep slopes include wood retaining walls, interlocking concrete blocks, rock retaining walls, riprap (loose rock) areas, and terracing. If you choose wood, make sure the wood is treated with a wood preservative to prevent rotting.

Below are a few ideas for hill stabilization.

1. Roots and Shoots. There are many ways to shore up a hillside to prevent soil erosion.
2. Watering on a Hillside. Water whisks quickly off a hillside leaving plants dry.
3. Stairs, Paths, and Rocks.
4. Dry Creek Beds.
5. Middle Ground.

5 Steps for Erosion Control on Steep Slopes and Embankments

1. Plant Grass and Shrubs. Grass and shrubs are very effective at stopping soil erosion.
2. Use Erosion Control Blankets to Add Vegetation to Slopes.
3. Build Terraces.
4. Create Diversions to Help Drainage.

Steep, sunny slopes are perfect for perennials such as daylilies, creeping phlox, lamb’s ears, stonecrop and a variety of ornamental grasses. A number of woody plants can also serve as good groundcovers, especially creeping juniper, fragrant sumac, bearberry, and Russian arborvitae.

When landscaping rocks to a slope, you must stabilize the stones so they don’t simply roll down the hill.

1. Select random spots staggered along the slope to place your rocks.
2. Dig indentations in the bank to hold the rocks in place, so they are secure and have no risk of rolling down and harming individuals or property.

Answer. Explanation: In hilly areas, soil erosion can be controlled by ploughing across countour lines, making use of terrace farming techniques and using strips of grasses to check soil erosion by wind and water.

Water. When it rains in the hilly areas, the soil gets washed away towards the plains. The running water deposits the mineral-rich soil in the riverbed and over the years this deposition of soil can change the course of the river. This can lead to floods which cause the destruction of life and property.

• Contour ploughing. Contour ploughing orients furrows following the contour lines of the farmed area.
• Terrace farming. Terracing is the practice of creating nearly level areas in a hillside area.
• Keyline design.
• Windbreaks.
• Cover crops/crop rotation.
• Soil-conservation farming.
• Mineralization.

In this process, the soil particles are loosened or washed away in the valleys, oceans, rivers, streams or far away lands. This has been worsening due to human activities such as agriculture and deforestation. Soil erosion is a continuous process that occurs either slowly or at an alarming rate.

The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

Different Soil Erosion 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.

Soil erosion is a naturally occurring process that affects all land forms. In agriculture, soil erosion refers to the wearing away of a field’s topsoil by the natural physical forces like water and wind. Major causes of soil erosion in India are over-cultivation, overgrazing, and deforestation.

Man’s ill gudged activities such as deforestation, overgrazing and faulty methods of agriculture have made soil erosion a serious national problem. Besides diversion of natural drainage courses, wrong orientation of roads and railways, embankments and bridges have also led to soil erosion.

In agriculture, soil erosion refers to the wearing away of a field’s topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.

wind , water , gravity erosion. There are three main types of soil erosion.
