The Water Cycle

How is it that we have water on earth? Does it change? 
Water on Earth does not stay in the same place, it moves constantly  due to a process called The Water Cycle, in which water goes from the oceans to the air to the ground and again back to the ocean, that is why it is called cycle.

Here are the steps in order of the Water Cycle:
§First, the sun heats water on earth. TRANSPIRATION
§Some of the water evaporates, turns from liquid to gas, or water vapor.
§Water gas (vapor) rises into the air.  EVAPORATION
§As it rises it cools.
§The cool causes the water to condense. CONDENSATION
§Change to droplets and join together until they create a cloud.
§When they are heavy enough ( all together) PRECIPITATION occurs.
Water falls back to earth as rain, snow, sleet, or hail as INFILTRATION
