Soil Erosion and Rock Formation

Water erosion is the process where running water washes away soil, reducing the land's agricultural potential.

Overgrazing occurs when cattle repeatedly graze a field, destroying grass and roots, which makes the topsoil exposed to erosion.

Deforestation involves clearing forests for agriculture and development, which removes tree roots that stabilize soil.
