Which of the following lists the main parts of the Hydrologic Cycle?

• A. Evaporation, Condensation, Precipitation, Infiltration
• B. Evaporation, Convection, Precipitation, Collection
• C. Evaporation, Sublimation, Precipitation, Collection
• D. Evaporation, Convection, Transpiration, Collection

Answer: (B)

The hydrologic cycle moves water through air and land in four main stages: evaporation, condensation, precipitation, and collection or infiltration. Water from seas, lakes, and soils evaporates into the air; that vapor cools and condenses into clouds; the water then falls as precipitation like rain or snow; and it collects in bodies of water or soaks into the ground to become part of the groundwater or run off into rivers. This sequence captures how water continually circulates on Earth. Convection is an atmospheric heat-transfer process, not a main stage of the water-cycle sequence, and sublimation or plant transpiration are ancillary or context-specific aspects rather than the core four steps. So the list that includes evaporation, condensation, precipitation, and collection/infiltration best represents the Hydrologic Cycle.
