What does the term 'evapotranspiration' denote in the water cycle?

Answer and explanation

Correct answer: The combined water loss by evaporation and transpiration

Correct answer: B. Evapotranspiration is the combined transfer of water from land to the atmosphere by evaporation and plant transpiration. Evaporation occurs from soil, open water, wet surfaces and other exposed areas. Transpiration is the release of water vapour from living plants, mainly through stomata in leaves. Hydrologists often consider the combined amount when estimating how much water leaves a land surface, although the exact contribution of each process can vary. A cloudburst in A is intense rainfall, not atmospheric water loss. C is melting, which changes ice to liquid water. D is underground movement and does not describe the combined upward transfer to the atmosphere. Memory cue: evapotranspiration = evaporation + transpiration.
