How can soil erosion cause floods?
Soil erosion can cause floods by removing the natural protective cover of vegetation on the land, which reduces the soil's ability to absorb water. This leads to increased runoff and sedimentation in rivers and streams, which can block water flow and increase the risk of flooding during heavy rain events.
Most soil erosion is caused by?
Water, wind, and human activities are the main causes of soil erosion. Water erosion, often from heavy rainfall or runoff, is the most significant cause of soil erosion globally. Wind erosion is more prevalent in drier regions with sandy soils. Human activities such as deforestation, overgrazing, and inappropriate agricultural practices can accelerate erosion rates.
How does the loss of ground vegetation influence water runoff and soil erosion?
The loss of ground vegetation can increase water runoff and soil erosion. Without vegetation, there are fewer roots to hold soil in place, leading to increased erosion. Additionally, water is not absorbed by plants, causing it to run off the surface and carry away soil particles, further contributing to erosion.
What are the two causes of soil erosion explain?
The two main causes of soil erosion are water erosion, which is caused by rainfall and runoff washing away soil particles, and wind erosion, where strong winds blow away topsoil. These processes are often exacerbated by human activities such as deforestation, overgrazing, and improper land management practices.
What Term is defined as movement off soil by water or wind?
Erosion is the term defined as the movement of soil by water or wind. It involves the detachment, transportation, and deposition of soil particles due to the force of water or wind. Erosion can lead to land degradation and loss of fertile soil.
What happens to a rangeland if it is overgrazed?
The vegetative growth is nearly killed off because it is eaten down to the soil. Which in turn could cause soil erosion.

This leads to increased runoff and sedimentation in rivers and streams, which can block water flow and increase the risk of flooding during heavy rain events.
How can overgrazing ang over cultivation cause soil erosion?
Grazing with hoofed animals such as cattle causes to topsoil to become compacted, and also breaks down soil structure. 'Poor' soil structure is when the soil does not form clumps (or aggregates), but instead exists as fine particles or dust. These fine surface soil particles are then easily blown away by wind or washed away by rain, causing erosion of soil. Compaction prevents rainfall from infiltrating (soaking into) the soil, and so much of it runs off, and this can also cause water erosion by washing away soil.
What would happen if trees in the mountain were cut and not replace?
There would be no trees on the mountain Soil erosion would occur this would cause run off

WHAT IS Problem cause?
Erosion cause the top soil to be washed a way this in turn brings about a situation where water is not retained in the soil causing degeneration in living material in the soil. As a result the soil drys out further and turns sandy and unable to sustain life leading to desertification. The washed out soil can also have a deleterious effect on the river and marine environments associated wit the run off.

How does levelling prevent soil erosion?
Leveling can prevent soil erosion by reducing the slope of the land, which decreases the speed at which water runs off the surface. This helps to prevent water from carrying away soil particles and causing erosion. Leveling can also promote better water infiltration and retention in the soil, reducing the impact of erosion.
What human activity most likely accounts for the most soil erosion?
Land use changes such as deforestation and clearing of natural land to create farms may be the largest contributor to soil erosion. Although natural causes such as runoff of rainwater especillay in slopy areas also cause soil erosion. When trees are cut off and land is cleared there is no tree or shrub roots to hold the soil on the surface and when it rains or is windy soil is eroded.
How does terracing help to prevent soil erosion?
Terracing helps prevent soil erosion by reducing the slope of the land, which slows down the flow of water across the surface. This allows water to infiltrate into the soil, reducing runoff and minimizing the occurrence of erosion. The terraces act as barriers to prevent soil from being washed away by heavy rainfall or irrigation.
