Answer: Evaporation and condensation are the two changes in state which are most represented in water cycle.
Explanation:
A process of circulation of water by passing through different states between the atmosphere, oceans and land is known as water cycle.
In water cycle, the most represented changes in state are evaporation and condensation. As during evaporation, the water present in the oceans, rivers, wells or on the land evaporates because of the heat from the sun as a result the liquid state is changing into gas.
Whereas, during condensation gas or water vapours changes into liquid. For example, when water condenses in the atmosphere it results in the formation of clouds.
Thus, it can be concluded that evaporation and condensation are the two changes in state which are most represented in water cycle.
