Answer 2

$\star$ Answer :-

Option b)

Cutting down of trees

Soil erosion is caused due to cutting down of trees.

Additional Information :-

>> Soil erosion refers to the removal of the top soil by various agents of gradation, causing a loss to soil fertility.

>> It happens because of physical factors such as slope of the land, intensity of the rainfall, and velocity of the wind.

>> The two most common types of soil erosion are -

• Sheet Erosion
• Gully Erosion

>> Sheet Erosion - It is relatively even erosion of a layer without formation of channel, which generally takes place on sloping land after rainfall.

>> Gully Erosion - it is the formation of deep grooves caused by heavy rainfall, giving rise to ravines or badlands.

Example - badlands of Chambal Valley.
