Explanation of denudation, gully, sheet, and wind erosion.
The denudation of the soil cover and subsequent washing down is described as soil erosion.
Usually, soil formation and erosion happen simultaneously in a delicate natural balance. However, human activities like deforestation, over-grazing, construction, and mining frequently disrupt this equilibrium.
Visual comparison of gully vs sheet erosion.

Gullies carve deep physical channels, whereas sheet erosion strips away broad flat layers of topsoil.
Farming methods to prevent erosion.
Defective methods of farming, like ploughing up and down a slope, can form quick-flowing channels that accelerate soil erosion.
To prevent this, agriculture relies on specialized land management techniques designed to slow down water and block the wind.
Fill in the blanks for conservation techniques.
The denudation of the soil cover and subsequent washing down is described as . Running water cuts through clayey soils to make deep channels known as . Land that becomes unfit for cultivation is called , which in the Chambal basin are referred to as . When water flows over large areas down a slope and washes away the top soil, it is known as . decelerates water flow down slopes by ploughing along contour lines. Leaving strips of grass between crops to break the force of the wind is known as . Planting rows of trees to stabilize sand dunes in western India involves creating .
