In the hydrologic cycle, evapotranspiration represents the combined loss of water by:
Correct answer: D. Evaporation and plant transpiration
- A. Condensation and precipitation
- B. Infiltration and groundwater flow
- C. Surface runoff and channel storage
- D. Evaporation and plant transpiration
Explanation
Evapotranspiration combines evaporation from soil and water surfaces with transpiration from vegetation. Infiltration and groundwater flow describe movement into or through the ground, not atmospheric water loss by this process.

About Hydraulics and Water Resources
Hydraulics studies fluid properties, pressure, buoyancy, continuity, Bernoulli's equation, momentum, pipe flow, open-channel flow and hydraulic machines. Water resources extends these principles to pumps, turbines, reservoirs, irrigation, floods and hydrology, while distinguishing laminar from turbulent flow and uniform from gradually varied channel flow.
