B. 1: Precipitation, 2: Evaporation, 3: Sublimation, 4: Surface Run-off
C. 1: Precipitation, 2: Evaporation, 3: Sublimation, 4: Infiltration
D. 1: Precipitation, 2: Condensation, 3: Sublimation, 4: Surface Run-off


参考答案:  B


本题详细解析:
Flow 1 in the figure represents precipitation as it shows water falling fn9j fk1o9vfg+(4xas auo7scp .:4ky ky1+g y jrom clouds. Flow 2 shows the evaporation of water from the ocean into the atmosphere. Flow 3 shows the sublimation of snow on the mountain top, as the arrows flow from the snow to the atmosphere, representing the change from snow (solid) to water vapor (gas). Flow .xf1p7g:skcj4(fa ysok v +jo1 4kuy99 ga+ny 4 shows the movement of water on land surfaces which is surface run-off. Therefore the correct answer is option B.
