Which phrase best describes pollutants entering water from rainfall?

• A. Rain washes pollutants into surface water
• B. Runoff from croplands and logged forests
• C. Pollutants from Rainfall
• D. Plant Nutrients

Answer: (C)

Rainfall can move pollutants from land into water bodies, mainly by washing them off surfaces and carrying them into streams, rivers, and lakes. The best phrase to describe pollutants entering water from rainfall is the one that states rain washes pollutants into surface water because it captures the transport action of rainfall, not just the presence of pollutants. Saying “Pollutants from Rainfall” is vague and doesn’t convey how those pollutants actually reach the water. The other options either focus on specific land sources or on a type of nutrient, rather than the process by which rainfall introduces pollutants into waterways.
