Snow, sleet and hail are the forms of
- (a)precipitation
- (b)condensation
- (c)transpiration
- (d)evaporation
Correct — A, precipitation. Snow, sleet and hail are all solid forms of precipitation — water that has condensed in the atmosphere and then fallen to the ground under gravity. They differ only in how the water freezes: snow forms as ice crystals, sleet as frozen or refrozen raindrops, and hail as layered ice built up in strong thunderstorm updraughts.
- (b)condensation — Condensation is the change of water vapour to liquid (as in dew or fog); it is a stage before precipitation, not the falling itself.
- (c)transpiration — Transpiration is the release of water vapour from plants — an input to the atmosphere, not falling water.
- (d)evaporation — Evaporation turns liquid water into vapour; it acts in the opposite direction to precipitation.
In the water cycle, water evaporates, condenses into clouds, and then falls back as precipitation. Precipitation takes liquid forms (rain, drizzle) and solid forms (snow, sleet, hail), depending on the temperature of the air the drops fall through.
The distractors are all water-cycle terms. Only precipitation refers to water falling to the surface; condensation, transpiration and evaporation are other stages that add or change vapour.
- Precipitation is any form of water — liquid or solid — that falls from clouds to the ground.
- Snow forms as ice crystals; sleet is frozen or refrozen raindrops; hail is layered ice from thunderstorm updraughts.
- Condensation (vapour to liquid) produces clouds, dew and fog, and precedes precipitation.
- Evaporation and transpiration move water into the atmosphere as vapour.
- Confusing condensation (which makes clouds and dew) with precipitation (falling water).
- Thinking hail and sleet are the same — hail forms in updraughts, sleet is refrozen rain.
Groups solid water forms and asks their category — all are precipitation.
