Detailed explanation-1: -The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

Detailed explanation-2: -Water moves both naturally and through the actions of humans. Energy from the sun and the force of gravity drive the continual movement of water on Earth. Human activities impact the water cycle by affecting where water is stored, how it moves, and how clean it is.

Detailed explanation-3: -At its most basic, the water cycle is how water continuously moves from the ground to the atmosphere and back again. As it moves through this cycle, it changes forms. Water is the only substance that naturally exists in three states on Earth – solid, liquid, and gas.

Detailed explanation-4: -Water cycle is the process by which water continually changes its form and circulates between oceans, atmosphere and land. The major sources of freshwater are the rivers, ponds, springs and glaciers. The movements that occur in oceans can be broadly categorised as waves, tides and currents.
