Water is not created or destroyed - it's recycled! The water e have today is the same that has always exsisted on earth.  Water exists in three forms/phases: solid water (snow and ice), liquid water (water), or gas (water vapor).  Simiar to what their titles imply, liquid water is found in rivers, lakes, oceans, and groundwater. Snow and ice are solid water, and water vapor fills our atmosphere. 

 The Water Cycle is how  water changes phases or forms as it goes through the cycle. It goes through certain processes to become a liquid, solid, and gas. These processes include:

• Evaporation: process of liquid to gas. When water gets warm, water molecules start moving faster. Some move so fast they break away and float into the air. 
• Condensation: gas to liquid. As warm air rises, it cools. Cooler air can't hold as much water vapor, so the vapor condenses into tiny droplets of liquid water or ice crystals. Water droplets cluster together, forming clouds. 
• Precipitation: falling liquid or solid. When enough water condenses in a cloud, the drops get so heavy they begin to fall from the cloud. This is called precipitation. Water can fall as rain, snow, sleet, or hail depending upon the temperature. 
• Transpiration: when a plant takes up water from its roots, it eventually travels all the way to the leaves. Water evaporates from the leaf, which is called transpiration. 
• Infiltration: when it rains, some water runs off and collects in waterbodies. Some of water can also be absorbed into the soil and be stored underground in groundwater. This is called infiltration. 
• Sublimation: sometimes snow or ice can be heated so quckly it changes into water vapor without first melting into water. This is called sublimation.
