What is the flow of water through the soil called?

• A. Tombolo
• B. Surface stores
• C. Throughflow
• D. Traction

Answer: (C)

Throughflow is the movement of water through the soil, typically downslope within the soil layer after rainfall infiltrates. After water enters the soil, it travels horizontally through pores and larger cracks in the upper layers, driven by gravity and capillary forces, so it moves toward streams rather than staying on the surface or moving straight downward to groundwater. This lateral flow in the soil is what we call throughflow. It contrasts with infiltration, the entry of water into the soil, and with percolation, which is vertical downward movement toward groundwater. The other terms refer to different ideas: a tombolo is a landform, surface stores are water on the surface, and traction relates to sediment movement.
