Rainfall that is not absorbed by soil and travels to the ocean is called?

• A. Run-off
• B. Infiltration
• C. Percolation
• D. Condensation

Answer: (A)

Runoff is rainfall that isn’t soaked into the ground and instead flows across the surface into streams, rivers, and ultimately the ocean. This happens when the soil can’t absorb water fast enough—like when it’s already full or when the surface is hard or paved. Infiltration is the process of water seeping into the soil, while percolation is the deeper movement of that water down toward groundwater, and condensation is when water vapor in the air cools and becomes liquid. So when water moves over the land toward the sea, it’s runoff.
