Which pair correctly matches process and result?

Correct answer: वाष्पीकरण से जलवाष्प

Correct answer: A. Evaporation is a change in which liquid water at a surface becomes water vapour and enters the atmosphere. It may occur from oceans, lakes, rivers, wet soil, and plant or animal surfaces when water molecules gain enough energy to escape. Thus, “evaporation to water vapour” correctly matches a process with its result. Option B is wrong because condensation changes water vapour into liquid droplets or, under suitable cold conditions, ice; it does not produce dry sand. Option C is wrong because transpiration is the release of water vapour from plant leaves through small openings, not the formation of rock. Option D is wrong because the dew point is a temperature at which air becomes saturated and condensation may begin; it is not an earthquake and cannot cause one by definition. The question tests whether the student knows both the process and the resulting state or material. In a phase-change question, ask: what is the starting substance, and what does it become? Liquid water becomes vapour during evaporation. Memory cue: evaporation sends water upward as vapour; condensation brings vapour back into droplets.
