What term describes water being blocked from reaching the ground by vegetation?

• A. Infiltration
• B. Interception
• C. Lithosphere
• D. Throughflow

Answer: (B)

Interception describes rainfall being captured by vegetation surfaces such as leaves and stems, so it doesn’t reach the ground immediately. Water held on the canopy can evaporate back into the atmosphere (interception loss) or, after being shed from the leaves, reach the ground as throughfall. This process reduces and delays the amount of water that enters the soil and contributes to runoff. Infiltration is the water that actually soaks into the soil, throughflow is the lateral movement of water within the soil toward streams, and the lithosphere is the solid earth. So the term for water blocked from reaching the ground by vegetation is interception.
