Question

name the three activities of man that can destroy this layer ​

Answer 1

Answer:Overgrazing occurs when farmers stock too many animals such as sheep, cattle or goats on their land.  The animals damage the soil surface by eating the vegetation and either digging into wet soil or compacting dry soil with their hooves.

Overcropping is when the land is being continuously under cultivation and is not allowed to lie fallow between crops.  This constant farming of the land reduces the soils ability to produce valuable humus for soil fertility as it is constantly being ploughed or stripped for crop growth.

Deforestation is the cutting down of large areas of forests leaving an open, exposed landscape.  Deforestation occurs for many reasons such as the sale of wood, charcoal or as a source of fuel, while cleared land is used as pasture for livestock, plantations of commodities, and settlements. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity (drying of soil).  This human activity quickly accelerates natural erosion in two ways.  Firstly the removal of trees is a removal of nutrients and minerals from the soil as the source of humus is greatly reduced.  The natural dead organic material that supplies the soil with its humus is generally leaves that have fallen from the trees, animal droppings, tree fruit or decaying trees in the soil.  Secondly, deforestation accelerates soil erosion by leaving large areas exposed to heavy rainfall (which can cause leaching or flash floods) or wind erosion.   Without the roots of the trees to keep the soil structure in place the soil is loose and easier to erode.

Answer 2

Overgrazing

• When farmers keep too many animals on their property, such as sheep, cattle, or goats, they are said to be overgrazing.
• By consuming plants and either digging into wet soil or compacting dry soil with their hooves, the animals cause harm to the soil surface.

Overcropping

• When land is continually cultivated and not allowed to rest between crops, this is known as overcropping.
• Because the ground is repeatedly ploughed or stripped for crop development, it loses its potential to create important humus for soil fertility.

Deforestation

• Deforestation occurs when huge tracts of forest are chopped down, creating an open, exposed environment.
• Deforestation happens for a variety of causes, including the selling of wood, charcoal, or fuel, while cleared land is utilised for a variety of purposes.
• While cleared land is utilised for animal grazing, commodity plantations, and settlements, it is also used for agriculture.
• Habitat destruction, biodiversity loss, and aridity have all been caused by tree removal without adequate replanting (drying of soil).
• Natural erosion is hastened in two ways by human activities.
• To begin with, removing trees depletes the soil's nutrients and minerals by reducing the humus supply.
• Leaves that have fallen from trees, animal droppings, tree fruit, or rotting trees in the soil are examples of natural dead organic material that provides the soil with humus.
• Second, deforestation hastens soil erosion by exposing huge regions to severe rainfall (which might result in leaching or flash floods) or wind erosion. In the absence of the roots,
