Question: 1 / 605

What is described as the downward movement through the soil?

Leaching

Leaching is the correct answer because it describes the process of water carrying contaminants such as pesticides or fertilizers down through the soil layers, potentially contaminating groundwater in the process. Particle Drift, Dust Drift, and Spray Drift all refer to the movement of particles or droplets through air, not soil. Runoff is the movement of water over the surface of the land, not through the soil.
