What is Water Cycle?
The water cycle, also known as the hydrologic cycle or the H20 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 the atmosphere.
Precipitation
Condensed water vapor that falls to the Earth's surface. Most precipitation occurs as rain, but also includes snow,
hail, fog drip.
oRAIN - is liquid water in the form of droplets that have condensed from atmospheric water vapor and
then precipitated
oSNOW - form of flakes of crystalline water ice that fall from clouds.
oHAIL -It consists of balls or irregular lumps of ice, each of which is called a hailstone.
oFOG DRIP - forms when fog droplets condense on the needles or leaves of trees or other objects, and
drip to the ground.
