Answers Latest Update.
List the 5 characteristics that make water unique - ✔✔✔stable, high specific heat, great
buffer, expands at freezing, excellent solvent
Why is it critical that water stores a lot of energy? - ✔✔✔allows large bodies of water to
cool or heat Earth to maintain a temperature
List the elements of the hydrologic cycle including driving forces - ✔✔✔1/2-
Evapotranspiration
3-Condensation
4-Precipitation
5-Runoff
6-Inflitration
7-Subsurface flow
8-Base flow
9-Concentrated surface flow
10-interflow (seepage)
Driving forces:
1-Sun
2-Earth's rotation

, Stormwater
What path does most of the rainfall onto the land surface take in getting to the ocean? -
✔✔✔Runoff
Which hydrologic cycle element acts as a valve, essentially controlling how fast the
water moves? - ✔✔✔infiltration
Give an example of why it is important to think of the hydrologic cycle over the 3-D
landscape, and not just at a point - ✔✔✔at any given time you can find water in any of
the different locations, it is never in one place and its always moving. It has not starting
point
How do higher stormwater flow rates generally affect streams? - ✔✔✔In urban areas:
increase in sediment, causes narrower, deeper, straighter streams
In rural areas: Wider, shallower, windier streams
Describe why stormwater tends to move a lot of contaminants. List at least 3 problems
caused by sediment as a water contaminant. - ✔✔✔Most pollutants/contaminants are
on the surface.
1. clogging of streams
2. impact on aquatic environment
3. sediment carries pollutants with it
What are the 2 main problems caused by nitrogen as a water contaminant? -
✔✔✔Causes aquatic life growth, aquatic plants consume nutrients and die, consumed
by other organisms, causes nitrite
1. Eutrophicaton
