INTRODUCTION  The process by which water is circulated between the Earth and the atmosphere continuously is known as water cycle or hydrological cycle. It is an important process which sustain life on Earth as it plays an essential role in shaping our environment.  WHAT IS THE WATER CYCLE? It is a complex process which involves the movement of water in three phases that is liquid,solid(ice) and gas(water vapor). The water cycle involves the interactions of the atmosphere, oceans, lakes,rivers and the ground. The driving force for this process is solar energy which heats water in the oceans,lakes and rivers which causes it to evaporate in the atmosphere.  STAGES OF THE WATER CYCLE There are various stages of the water cycle which are as follows: ●Evaporation :   The sun heats the water present in oceans,lakes and rivers which causes it to evaporate in the atmosphere.  ●Condensation:   Water vapor cools down in the atmosphe...
