Freshwater/Groundwater Review
| Question | Answer |
|---|---|
| What is Freshwater? | water with little, no taste, smell, or color |
| What is Saltwater? | water that has dissolved salts or minerals |
| Percentage of saltwater on earth | 97% |
| Three forms of water | solid, liquid, gas |
| Saltwater | water that has dissolved minerals, |
| Three forms of water | solid, liquid, gas |
| Percentage of freshwater on earth | 3% |
| Why is water a unique substance | It exist as solid, liquid, and gas |
| What would Earth be like without water | divide |
| Process of water cycle where liquid water becomes vapor | Evaporation |
| What do artesian wells and springs have in common? | pumped natually from the ground |
| Process of water cycle where water moves into the ground | percolation |
| discharge | amount of water the stream carries |
| area of land where water from the divide flow | Drainage basin |
| What is gradient? | slope- change in elevation |
| continuous movement of land from which water flows in different directions | divide |
| What causes water to move from the divide to the drainage basin? | gravity |
| Most freshwater is found in | glaciers, icebergs |
| What do artesian wells and springs have in common? | pumped natually from the ground |
| Percentage of freshwate available to humans | less than 1% |
| rock layer that will not let water pass | slope- change in elevation |
| water located beneath Earth's surface | goundwater |
| Underground layer of rock that hold freshwater | aquifer |
| Layer of rock that allows water to flow through | permeable rock |
| Layer of rock that does not allow water to flow | impermeable rock |
| zone underground where water collects | zone of saturation |
| upper area underground that allow water to pass | zone of aeration (permeable) |
| hole that reaches the water table that can bring groundwater to the surface | well |
| continuous movement of water from Earth to the environment and back | water cycle |
| increase of nutrients in a lake or pond | eutrophication |
| rising and sinking of warm water and cold water layers in a lake | turnover |
| top area of the zone of saturation | water table |
| Place where groundwater flow to the surface naturally due to pressure | artesain well (spring) |
| Place where the watertable reaches the Earth surface | spring |
| large lake used as a water supply | reservior |
| river or stream that flow into another body of water | tributary |
| Where is most of Earth's freshwater found? | icebergs, glaciers |
| Name three things that affect stream or river erosion | gradient, discharge, load |
| material that a stream carries | load |
