The cyclic pattern in which water keeps moving from the ocean and the seas to the sky as water vapour, from the sky to the land as rain or snow and from the land to ocean and sea as surface water is known as water cycle.

The water cycle, also known as the hydrologic cycle or H2O cycle, describes the continuous movement of water on, above and below the surface of the earth. Water can change states among liquid,vapour, and solid at various places in the water cycle. Although the balance of water on Earth remains fairly constant over time, individual water molecules can come and go, in and out of the atmosphere..The water moves from one reservoir to another, such as from river to ocean , or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation , infiltration, runoff, and subsurface flow. In so doing, the water goes through different phases: liquid, solid, and gas

water from water bodies land fields or plant goes into the air in the form of water vapour form clouds and then comes back to the ground as rain, hailor snow is called water cycle

Water undergoes different processes in the environment and is found in different states during these processes. This cyclic process through which water circulates in the environment is called the water cycle. There are four main steps involved in water cycle:
1) Evaporation
2) Condensation
3) Precipitation
4) Run off
Evaporation is the process through which water is converted into water vapour. Heat or sunlight converts water into water vapour. Water is also emitted from the leaves of the plants through the process of transpiration.
This water vapour in the atmosphere condenses to form clouds through the process of condensation.
When enough water is condensed to form clouds, it falls down on the surface of the Earth in the form of rain, snow, hail, etc. This process is known as precipitation.
The water that falls down as precipitation runs through the rivers and seeps underground. It also flows off the surface as surface run off to join low-lying water bodies. In this manner, water is circulated in the environment.

The water cycle, also known as the hydrological cycle or H2O cycle, describes the continuous movement of water on, above and below the surface of the Earth. Although the balance of water on Earth remains fairly constant over time, individual water molecules can come and go, in and out of theatmosphere. The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, runoff, and subsurface flow. In so doing, the water goes through different phases: liquid, solid (ice), and gas (vapor).
