| Characteristics of water | 1) Temp range 0-100 degrees, 2) only is known to exist on earth, 3) odorless, 4) found in glaciers, air, ground, 4) when water freezes it expands, 5) for cleaning, drinking, 6) dissolves other things, a universal solvent |
| How is global water distributed in e.g. oceans? | 97.2% oceans; 2.15% ice caps/ glaciers, .062% groundwater, .018% fresh water lakes, .0089% salt water lakes, .005% soil moisture, .001% atmospheric water, .0001% rivers |
| Water used by plants and animals and people is nver destroyed, but is used and reused byliving and non living forms. It is powered by _____? | It is the earth's plumbing system powered by the sun. The water is continually purified for reuse. |
| What is it called when water rises from a body of water into the atmosphere? | evaporation |
| What is it called if water rises from living plants? | Transpiration |
| What happens after water transPires (rises from living plants) or evaporates (rises from body of water)? | The water condenses and sits in clouds. |
| What happens after water condenses in clouds? | Precipitation occurs in the form of rain, sleet, snow or hail. |
| When water hits the ground, it can either do what? | It can either 1) soak into the ground (infiltration) or 2) seep off into the dribble down into other lakes, rivers, and reservoirs (called run-off). |
| What is run-off? | Runn off is when water hits the ground and seeps off the dribble down into other lakes, rivers and reservoirs. |
| What is infiltration? | When water hits the ground and it soaks into the gound. |
| What is an aquifer? | An underground layer of permeable rock, sediment (usually sand or gravel), or soil that yields water. Water that sinks into th ground gets held in an aquifer. |
| What is the main source of energy for the water cycle? | The sun |
| What is an addition equation for the water cycle's water? | Evaporation + transpiration = Precipitation |
| Renewal Time (def) | The time required for all water in a body of water to be replaced or renewed. |
| The renewal time depends on ?? | 1) rate of flow (faster flow has a quicker renewal), 2) the volume in the body of water |
| Which has a faster renewal time - a river or an ocean? | A river - less volume |
| Which has a faster renewal time Lake Michigan or polar ice caps? | Lake Michigan |
| What is the renewal time for a glacier? | 20 to 100 years |
| What is the renewal time for seasonal snow? | 2 to 6 months |
| What is the renewal time for soil moisture? | 1 to 2 months |
| What is the renewal time for shallow groundwater? | 100 to 200 years |
| What is the renewal time for deep groundwater? | 10,000 years |
| What is the renewal time for lakes? | 50 to 100 yars |
| What is the renewal time for rivers? | 2 to 6 months |
