The Water Cycle Water Enters the atmosphere as water vapor through – Transpiration-leaves plants through their leaves – Evaporation-from lakes, rivers, oceans. Water vapor becomes water when – Condenses in the air and forms clouds Water returns to earth – Through precipitation Absorbed by Earth – Infiltration (Percolation) to form groundwater – Runoff into lakes and streams

Activity Roll Your Way through the Water Cycle – Complete all the boxes for the travels. You may only stay at a station two times in a row. After two rolls at a station you must continue rolling till you move You can return to any station once you have left it – Use your journey to create a cartoon for Wally Water-droplet. Each box represents a roll at a station Use captions to explain what is going on in the story. – Cartoon is due tomorrow.

Where is all our water??? On the box containing a single water droplet. Please divide the water droplet and color the portion of the water on earth that is fresh blue and the portion of the water on earth that is salt water yellow.

97 % Of Earth’s Water Is Saltwater (Ocean water) Only 3 % of the water on Earth is Freshwater and useable by Humans, animals, and plants.

Such A Small Amount Of Fresh Water The 3% of useable fresh water is found – On the surface – As groundwater – Frozen in Glaciers and Ice Caps

Surface Water Is Found As 69% Ground Ice and Permafrost 20.9% Lakes 3.8% moisture in the soil 2.6 % swamps and marshes 0.49% Rivers 0.26% In living things 3% Atmosphere

Most Freshwater on Earth is FROZEN
