Term
| what is the hydrologic cycle? |
|
Definition
| a cycle describing how water moves between the atmosphere, land masses, and the ocean |
|
|
Term
| what are the major fluxes of the hydrologic cycle? |
|
Definition
| precipitation, surface runoff, groundwater flow, evapotranspiration (lquid-->atmosphere from pulling water out of soil) |
|
|
Term
| what are the major drivers of the hydrologic cycle |
|
Definition
| driven by gravity and solar power |
|
|
Term
| landscape controls on surface water- list 2 changes along flow paths-be able to describe these changes |
|
Definition
1. physical changes such temperature and particles
2. chemical changes such as leaching, reactions, dissolutions and more |
|
|
Term
| landscape controls on surface waters- describe the balances of different flow paths feeding lakes and streams |
|
Definition
-different flow paths have distinct physical and chemical characteristics
-different collection of flow paths leading to different limnology |
|
|
Term
| what are two different collections of flow paths |
|
Definition
1. surface runoff (overload flow)
2. groundwater flow (groundwater-->wingra-->mendota) |
|
|
Term
| what is the unsaturated zone? |
|
Definition
| the subsurface water held tightly by capillary force, right below the soil-water zone |
|
|
Term
| what is the saturated zone? |
|
Definition
|
|
Term
| what is ground water recharge? |
|
Definition
| input to ground water from precipiation or surface waters |
|
|
Term
| what is groundwater discharge? |
|
Definition
| output from groundwater into surface waters such as springs and seeps |
|
|
Term
| what is the water table? what are some characteristics? |
|
Definition
part between unsaturated and saturated zone
-small near permanent water bodies
-depth fluctuates over time due to difference in recharge, withdrawl and evoptranspiration |
|
|
Term
| is the water table depth dropping or getting higher becuse of urbanization? |
|
Definition
| dropping due to groundwater pumping) ex in class revrsed the direction of groundwater flow from mendota |
|
|
Term
| Why can adjacent lakes be very different from one another in Northern Wi? |
|
Definition
| due to groundwater influence on surface water- can have major effects on lakes, streams and wetlands |
|
|
Term
| what is lake landscape position |
|
Definition
| a lake's location relative to the type and stregnth of its connection to a drainage network |
|
|
Term
| how does groundwater influence lake landscape position? |
|
Definition
| related to hydrology... highland lakes have lower groundwater input vs lowland lakes ("drainage lakes") |
|
|
Term
| lake position (aka groundwater influence)effect a lake |
|
Definition
change in conductivity:
- increase GW, increase conductivity (lower lake position)... GW carries ions from weathering
-increase GW increase fish species (or chlorophyll) and lower lake position |
|
|
Term
| larger lakes have ___ water and thus __ havitat diversity and thus __ species divirsity (more or less) |
|
Definition
|
|
Term
| desert fishes will build nests in bed areas of ground water ___ because it has enough ___ and groundwater is cool |
