Question

which step from the water cycle is driven by gravity? condensation precipitation evaporation respiration which stage of the water cycle is driven by losing energy? condensation precipitation evaporation runoff which stage in the water cycle is driven directly by the suns energy? * precipitation condensation transpiration evaporation

Explanation:

1. Gravity causes water in the atmosphere to fall as rain, snow, sleet, or hail, which is precipitation. Condensation is the change of water from gas to liquid due to cooling, evaporation is the change from liquid to gas due to heat, and respiration is a biological process not part of the water - cycle steps relevant here.
2. Condensation occurs when water vapor loses energy and changes from a gas to a liquid state. Precipitation is mainly driven by gravity, evaporation requires energy gain (from the sun), and runoff is movement of water on land due to gravity.
3. Evaporation is the process where water changes from a liquid to a gas state directly due to the sun's heat energy. Precipitation is driven by gravity, condensation is cooling - driven, and transpiration is water loss from plants.

Answer:

1. precipitation
2. condensation
3. evaporation
