8Sci_Water Dynamics
Introduction to Water Dynamics
| Question | Answer |
|---|---|
| What are three ways dynamic water bodies continuously change? | physically, biologically, and chemically |
| What would be considered a global water reservoir in the water cycle? | the atmosphere |
| What is a watershed? | a region of land draining into a stream, river, pond, lake or other body of water |
| What is a watershed divide? | the boundary of a watershed |
| How can the atmosphere be considered part of the hydrosphere? | It is a source of water |
| What three factors do the characteristics of watersheds depend on? | Geology, Climate & Vegetation |
| What is the hydrologic (water cycle)? | the movement of water between the various global water reservoirs |
| Has the total amount of water on Earth changed? Explain. | No, we are drinking the same water the dinosaurs used over 65 million years ago |
| What is economic trade-off? | when communities need to purchase water from other sources |
| What is the goal of watershed management? | to balance multiple competing demands using scientific studies and human judgment |
| What are two competing interests for water resources? | Economic Development and Preserving Natural Ecosystems |
| When developers and environmental activists concerns collide is the water in short supply, too much or contaminated? | Water is in short supply |
| Is the water in short supply, too much or contaminated when farmers are pitted against recreational users? | Water is contaminated |
| Is the water in short supply, too much or contaminated when conservation of available resources is important? | Water is in short supply |
| Is the water in short supply, too much or contaminated when water supplies contain improperly disposed chemicals? | Water is contaminated |
| Is the water in short supply, too much or contaminated when you identifiy new sources of water? | Water is too much |
| Is the water in short supply, too much or contaminated when there is flooding after a large storm? | Water is too much |
| Is the water in short supply, too much or contaminated when protection of drinking water reserves is critical? | Water is in short supply |
| What does the way water flows over the land define? | the boundaries of river basins and watersheds |
| What would be considered a global water reservoir in the water cycle? | the atmosphere |
| What is dew an example of? | condensation |
| What body of water doesn't contribute water vapor into the atmosphere? | aquifers |
| Where does most of NC's drinking water come from? | groundwater, lakes & rivers |
| What would you find readily available in our rivers, lakes and streams? | fresh water |
| Where is most of the freshwater on Earth located? | icecaps and glaciers |
| What are aquifers? | where groundwater supplies are stored |
| How does groundwater help to keep surface waters full? | it is stored in aquifers and slowly moves into riverbeds |
| What are wetlands? | heavily vegetated areas that are saturated with water for at least part of the year |
| What is an example of wetlands? | swamps, bogs & marshes |
| What are 4 important functions of wetlands? | 1)help reduce flooding, 2)maintain the flow in streams & rivers during dry periods, 3)help purify water that flows through them, 4)provide a rich variety of habitats that support a diverse system of living things |
