Final answer:
Silting is the process of sediment accumulation in bodies of water or canals. It is caused by factors like erosion, deforestation, and human activities such as construction and agriculture.
Step-by-step explanation:
Silting is the process of sedimentation or accumulation of fine particles, such as silt, clay, and sand, in bodies of water or canals. It occurs when the velocity of the water decreases, causing the particles to settle and form layers. Silting can be caused by various factors, including erosion, deforestation, and human activities such as construction and agriculture. For example, when deforestation occurs, the removal of trees and vegetation exposes the soil to erosion, leading to sedimentation in nearby water bodies.
