Which process describes water that flows over the land after rainfall and can feed rivers?

• A. Run-off
• B. Condensation
• C. Evaporation
• D. Precipitation

Answer: (A)

Runoff is water that flows over the land after rainfall and can feed rivers. After rain, some water soaks into the soil, but the excess that can’t infiltrate will move across the surface, running downhill and into streams. This surface flow is what carries rainwater from fields and streets into rivers, helping sustain them. It’s influenced by how steep the land is, what the surface is like (soil, vegetation, or pavement), and how saturated the ground is. By contrast, evaporation is water turning into vapor and rising, condensation is vapor turning into liquid in clouds, and precipitation is rain or snow falling from the sky.
