The document discusses the global water cycle and distribution of water on Earth. It explains that 97% of water is ocean water and 3% is fresh water. Fresh water is found primarily as ice caps and glaciers (68.7%), groundwater (30.1%), and other fresh surface water sources. The hydrologic cycle describes the continuous movement of water through evaporation, precipitation, and runoff between oceans, atmosphere, and land. River systems are made up of river sources, mouths, floodplains, tributaries, and watersheds that drain into larger bodies of water. Groundwater is fresh water stored underground in aquifers and contributes to drinking water and irrigation needs.

2. Water Distribution Water is distributed all over the world! Some places may have more than others. The different places water is distributed are polar ice caps, oceans, groundwater, and fresh water. 97% is ocean water 3% is fresh water

3. Fresh Water Distribution 68.7% Ice caps and glaciers 30.1% Ground Water 0.9% is other Fresh Surface Water 0.3% 87% lakes 11% swamps 2% rivers This information was found on http://ga.water.usgs.gov/edu/waterdistribution.html

4. Hydrologic Cycle The Hydrologic cycle, also called the water cycle, is a transportation of water through gas, liquid, and solid states. http://www.cotf.edu/ete/images/modules/msese/earthsysflr/EFCycleP3.gif

5. Hydrologic Cycle This is a more descriptive Hydrologic cycle image. http://www.water.ky.gov/NR/rdonlyres/D34B71E0-E304-4285-9112-B606FCE66C75/0/HydrologicCycle.jpg

6. Hydrologic Cycle The Hydrologic Cycle (water cycle) goes through many states or forms. Water can be evaporated from the ocean,end up in the mountains, and run down its sides. The Hydrologic Cycle is continuous, which means there is no beginning and no end. Water supply on earth has been at the same level as it was in the beginning of time! That means that all water on earth now was on earth during caveman times!

7. River Systems A river system is the combination of stream channels draining a river basin. http://pakistanfront.files.wordpress.com/2009/05/indus-river-system.jpg

8. River System A river system is made of many different parts. River source River mouth Wetlands Floodplains Main river and tributaries Meanders Watershed

9. River Source and River Mouth The river source is where the river begins, most often in the mountains. The river mouth is where the main river drains into a bigger body of water, like an ocean, a lake, or another river. http://www.vhpamuseum.org/Places/images/River%20Mouth.jpg Mouth Source http://thumbs.dreamstime.com/thumb_351/1231238090izq80B.jpg

10. Wetlands Wetlands are areas where water and land meet. Wetland areas have been so saturated with water that the soil is always wet. Wetland areas have plants that are adapted to living in this kind of soil. Marshes, swamps, and bogs are types of wetland areas. http://www.kidsgardening.com/2005.kids.garden.news/october/pg1.html

11. Floodplains A floodplain is an area of mostly flat land along either side of a river which often floods after heavy rains. A floodplain’s soil is often rich in nutrients which have been deposited by a flooding river. A floodplain is an excellent area in which to grow food because of the rich soil. http://cgz.e2bn.net/e2bn/leas/c99/schools/cgz/accounts/staff/rchambers/GeoBytes%20GCSE%20Blog%20Resources/Images/Rivers/Floodplain_Tay.jpg

12. Main River and Tributaries The main river is the primary course of a river. Tributaries are smaller streams or rivers that feed into the main river. http://image.absoluteastronomy.com/images/encyclopedisimages/w/wp/wpdms_nasa_topo_judith_river.jpg

13. Meanders A meander is a turn or a loop in a river. A river that meanders does not flow straight, but has lots of curves. Rivers that are older have more meanders than more recently developed ones. http://www.stacey.peak-media.co.uk/Year7/7-7Rivers/7-7Meanders/341.jpg

14. Watershed A watershed is an area of land that is drained by a river system. A watershed is also known as a drainage basin or a river basin. http://geoscape.nrcan.gc.ca/h2o/bowen/acquire_e.php

15. Groundwater Groundwater is fresh water that has collected beneath the earth’s surface. Most groundwater is found in aquifers or underground streams. Groundwater is used for irrigating crops, drinking water, and public use (such as firefighting and public swimming pools). Many industries and mining facilities depend on groundwater. In 2000, 21% of water used in the U.S. was from groundwater. http://ga.water.usgs.gov/edu/wugw.html
