Condensation is the process by which a gas changes to its liquid form on cooling

vaporisation is the process by which a liquid changes to its gaseous form on heating

Freezing is the process by which liquid water changes to its solid form on cooling.

Hail: Pellets of frozen rain that flow in the shower from clouds.

Precipitation is the falling down of condensed water vapour present in the atmosphere in the form of rain, snow or hail.

water conservation means saving water for use in future.

water cycle is the continuous process by which water circulates between the earth's ocean, atmosphere and land, involving precipitation as rain and snow, drainage in steams and rivers, and return to the atmosphere by evaporation and transpiration.

Water pollution means the addition of unwanted material to water.

The rainwater also fills up the lakes and ponds. A part of the rainwater gets absorbed by the ground and seems to disappear in the soil. Some of this water is brought back to the air by the process of evaporation and transpiration. The rest seeps into the ground. Most of this water becomes available to us as ground water. Open wells are fed by ground water. Ground water is the source for many lakes as well. It is also this groundwater which is drawn by a handpump or a tubewell. The more handpumps or tubewells that are used in an area, the deeper we need to dig to find this ground water. The loss in the level of ground water due to over use, is worrisome.
