Terrace farming on hilly slopes positively affects which stage of the water cycle?

Correct answer: It slows surface runoff and increases infiltration

The correct answer is B. Terrace farming divides a steep slope into a series of nearly level steps. These steps interrupt the downward movement of rainwater, reduce the speed of surface runoff, and allow more time for water to soak into the soil. This process is called infiltration. Better infiltration can support soil moisture and groundwater recharge, while reduced runoff also lowers soil erosion. A is incorrect because terraces do not primarily increase evaporation; their main hydrological effect is slowing and retaining water. C is incorrect because terraces do not directly control atmospheric temperature or snowfall. D is incorrect because water is not destroyed; its movement and storage are changed. The important chain is: terraces slow flow, slower flow allows infiltration, and infiltration improves water entry into soil.
