Question

differentiate between manmade causes and natural causes of soil erosion

Answer 1

Answer:

MANMADE CAUSES -

1] WE CUT TREES AND CUTTING TREES CAUSES SOIL EROSION.

2] The farming practices are the major cause of soil erosion. The agricultural activities disturb the ground.

3] HUMANS ARE DOING POLLUTION AND THERE IS GLOBAL WARMING.

   GLOBAL WARMING DESTROYS THE SOIL FERTILLITY. THUS, IT CAUSES    

    SOIL EROSION.

NATURAL CAUSES -

1] SOMETIMES EXCESS RAINFALL CAUSES FLOODING AND TAKES THE SOIL WITH IT CAUSING SOIL EROSION.

2]  SOMETIMES STORMS AND CYCLONES TAKES THE SOIL WITH IT THROUGH AIR CAUSING SOIL EROSION.

3] VOLCANOES ERUPT  THE HOT LAVA AND IT FLOWS TO NEARBY LAND. THE EXCESS HEAT OF THE LAVA DESTROYS THE SOIL FERTILLITY AND CAUSES SOIL EROSION.

Answer 2

Differences between manmade and natural causes of soil are as follows:

• Manmade causes of soil erosion are deforestation, overgrazing, mining and construction, and agriculture.

• Soil erosion happens through agriculture when the crops are planted and the top layer of soil is shifted which causes erosion.

• The natural causes of soil erosion are water, wind, etc.

• When flooding takes place in a particular place, the running water takes away the top layer of the soil thereby causing soil erosion.

• When high-velocity wind or wind storms occur they affect the layer of soil by displacing it.

These are the different causes of erosion of soil.
