A.Effect of pressure on the melting point of a solid
B.Effect of pressure on boiling point of a solid
C.Inter conversion of states of matter
D.Change in composition of matter

Answer 1

Hint:To answer this question you must recall the steps of the water cycle and the changes occurring throughout the process. In the water cycle water undergoes a change in state many times.

Complete step by step answer:
The water cycle, which is also termed as the hydrological cycle, gives a description of the continuous movement of water above, below and on the surface of earth. The major processes involved in the water cycle are evaporation of water, transpiration, melting of snow, sublimation of snow, deposition of gas, advection, condensation and precipitation.
Since from the various processes in the water cycle, we can clearly see that they involve the conversion of water from one phase to the other, thus, we can say that water cycle is an example of inter conversions of the states of matter.

Hence, the correct option is option C.

Note:
Evaporation is the transformation of water from the liquid state to vapour phase from water bodies to the atmosphere. Transpiration is the release of water vapour from the plants into the atmosphere. Sublimation of snow is the direct change of state from solid water to water vapour surpassing the liquid state. Deposition is quite the opposite of sublimation which involves the direct conversion of water vapour into ice.
After water from various sources on the earth evaporates as vapour into the atmosphere, the vapour moves into the atmosphere. This movement is known as advection. If it were not for advection, the water that evaporates form the oceans, would not precipitate over land.
As the air cools as we go higher in the atmosphere, the water vapours begin to condense into liquid water droplets forming clouds and fog. Then the condensed water droplets fall on the earth’s surface as rain, snow, fog drip, hail and sleet. All these processes collectively are known as precipitation.
