As water moves through the water cycle it undergoes various types of changes. Three of the major places that water changes its state are melting at the polar ice caps, evaporation of water from rivers and lakes, and precipitation of water (snow, rain, sleet) from the sky to the earth.
Describe the type of change, chemical or physical, that takes place at each stage of the water cycle by providing evidence that supports your answer.

Answer:
at each stage of water cycle , it undergoes physical change of state or phase change . melting of ice at ice caps is due to absorption of heat which causes ice to melt ( solid to liquid) and this process requires a huge amount of heat latent heat of fusion, evaporation also takes place due to absorption of heat . these expansions occur due to after absorbing heat the molecules become more energetic and their kinetic energy increases and they move apart resulting in volume expansion. on the other hand during precipitation condensation occurs and the gas phase releases heat to come back to liquid form as the molecules come closer after evolving heat to the surrounding. condensation occurs when the water vapour comes in a cool environment.
