PPT-Surface water

One watershed is separated from another by a ridge of land called a dividebrStreams on each side of the divide flow in different directionsbrThe Great Divide is the longest divide in North America It follows the line of the Rocky MountainsbrWest of the divide water flows toward the Pacific OceanbrSome water is trapped between the Rockies and the Sierra Nevadas in the Great BasinbrBetween the Rocky and Appalachian mountains water flows toward the Mississippi River and into the Gulf of Mexico.

Study Scope/Steps. Retrofitting to manage . surface water. Retrofitting to manage surface water. A great . opportunity. Why . retrofit?. What we can retrofit. The benefits of . retrofitting - differently. Guidance overview. Y. ou must know…. where water is. h. ow water moves. AND. w. hy water is an important abiotic (nonliving) factor within an ecosystem. Where does water go?. When water falls to Earth, some water soaks into the ground becoming part of groundwater.. Why Water is Special. Why do we study water properties in biology class?. About 2/3 of the mass of a cell is water!. Most life-sustaining reactions occur in water solutions. Polarity. Polarity describes the distribution of electrons in a molecule.

All forms of life from bacteria to plants and animals, use water as a medium for chemical reactions as well as the transport of materials within and among cells..

Water is everywhere! It makes up about 70% percent of the Earth’s surface. Of that water, about 97% is ocean, and only 3% is fresh water. How Much Fresh Water Is on Earth?. 3%. Chemical Structure of Water. Water is composed of two atoms of Hydrogen (H) and one atom of Oxygen (O).. The chemical structure of water looks a lot like a famous Mouse- M-I-C…K-E-Y…M-O-U-S-E. The head being the O and the ears being the H.. Key points (what your kiddos REALLY need to understand!). We . cannot. consider surface water without thinking about groundwater. Groundwater and surface water do not flow the same way. Interactions between groundwater and surface water may “shift” as a result of other factors.
