How does erosion gives a bad and good effect?

Answer 1

Erosion wears away materials. For example the sea erodes cliffs and rocks because the salt in the water rubs against the rock creating friction. The same happens in deserts. The sand is blown up and wears away rocks creating different shapes. Acid rain also causes a form of erosion, and in time monuments and buildings may wear away.

Answer 2

Approximately 40% of the world's agricultural land is seriously degraded.[5] According to the UN, an area of fertile soil the size of Ukraine is lost every year because of drought, deforestation and climate change.[6] In Africa, if current trends of soil degradation continue, the continent might be able to feed just 25% of its population by 2025, according to UNU's Ghana-based Institute for Natural Resources in Africa.[7]

When land is overused by animal activities (including humans), there can be mechanical erosion and also removal of vegetation leading to erosion. In the case of the animal kingdom, this effect would become material primarily with very large animal herds stampeding such as the Blue Wildebeest on the Serengeti plain. Even in this case there are broader material benefits to the ecosystem, such as continuing the survival of grasslands, that are indigenous to this region. This effect may be viewed as anomalous or a problem only when there is a significant imbalance or overpopulation of one species.

In the case of human use, the effects are also generally linked to overpopulation. When large number of hikers use trails or extensive off road vehicle use occurs, erosive effects often follow, arising from vegetation removal and furrowing of foot traffic and off road vehicle tires. These effects can also accumulate from a variety of outdoor human activities, again simply arising from too many people using a finite land resource.

One of the most serious and long-running water erosion problems worldwide is in the People's Republic of China, on the middle reaches of the Yellow River and the upper reaches of the Yangtze River. From the Yellow River, over 1.6 billion tons of sediment flows into the ocean each year. The sediment originates primarily from water erosion in the Loess Plateau region of the northwest.

Answer 3

Erosion is a natural process that would occur with or without the presence of humankind. It is therefore neither good or bad. While it erodes mountains and soil, it also normally deposits that material somewhere else, as in river deltas.

Answer 4

in some ways gaddafi
For example, Coastal erosion. Longshore drift 'steals' beaches, leaving cliffs exposed. The sea erodes the cliffs with it's incessant waves, causing the land to fall, destroying whatever trees etc. Was on it. In the same way, rivers widen their banks at the expense of the organisms on the banks. Wind blows sand, which erodes rocks. Rocks in the desert are most affected. The result is that the habitats of desert lizards etc. are destroyed. There are further erosion types, but the general answer is the erosion results indirectly in the destruction of habitats especially on the coast.

Answer 5

Depends on the nature of the erosion.

Most cases of erosion being "bad" are due to loss of property. A river erodes farmland, or ocean waves cut away shoreline.

Extreme cases are Landslides of varying degrees, Large landslides can trigger massive waves if they occur underwater, threatening Coastlines. Any slide on land is potentially "bad" if humans or their interests are involved.

Answer 6

It depends on how the situation is it can be both good and bad.

Answer 7

it scatter the soil to dead areas to create fertile lands

Answer 8

eroison can be either good or bad. Eriosion is very good because u poop & it comes out & i poop all the time

Answer 9

Erosion can make the soil good for plantation, but it is bad because then there will not be enough land.
