% of earths water that is fresh - answer2.5
where does water at unh come from - answer oyster and lamprey rivers
5 major watersheds in NH – answer Conneticut, Androscoggin, Saco, Merrimack,
Piscataqua
consumptive water use - answer means water can't be reused because it evaporates
non-consumptive water use - answer water returns to the environment and can be
reused (but may be degraded)
What kind of molecule is water? - answer polar molecule (dipole)
polar compound - answer unequal charge distribution
Hydrogen bond - answer An intermolecular bond between a locally positive hydrogen
atom and a locally negative atom (usually oxygen)
Cohesion - answer attraction of water molecules to each other
Adhesion - answerattraction of water molecules to other surfaces
Capillarity - answerWater rises due to attraction of H atoms in water to O atoms in glass
(hydrogen bonding)
Triple point - answertemp and pressure combination in which pressure combination in
which perfect balance exists between perfect balance exists between all 3 phases
Temp ar which water is most dense - answer4C
specific heat of ice - answer.5 cal/g degC
Specific heat of water - answer1 cal/g degC
Latent heat of fusion - answer80 cal/g
latent heat of vaporization - answer540 cal/g
Water Budget Method - answerchange in volume = inflows - outflows
, Potential Evapotranspiration - answerWater loss which will occur if at no time there is a
deficiency of water in the soil for use by vegetation (limited by energy not water usually)
REQUIREMENTS FOR precipitation - answerSaturated conditions, condensation on a
nuclei, growth of water droplets to rain drops
when is precepts more likely - answerwhen temp decreases
why adiabatic cooling occurs - answerair expands
convective lifting - answercaused by unequal heating at earth's surface (warm air lighter
than cold!)
orographic lifting - answercloud formation that occurs when warm moist air is forced to
rise up the side of a mountain
lifting by frontal collision - answercold and warm fronts collide forcing the warm front up
Ways fog forms - answercooling air, rapid evaporation of water into air, mixing of air
parcels
Valley fog - answerthe settling of cooler, more dense air in low-lying areas; produces
saturated conditions and fog
advection fog - answera fog formed when warm, moist air is blown over a cool surface
(often occurs on coasts)
upslope fog - answerFog formed as moist, stable air flows upward over a topographic
barrier
steam fog - answercondensation of water vapor that results when cool air moves over
warm water
Fog created by mixing parcels of air - answerformed by the mixing of two unsaturated
air parcels (exhaling)
Interception - answerPrecipitation that is captured by vegetation and returned to
atmosphere as water vapor
Stemflow - answerPrecipitation that strikes vegetation and runs down stems
Throughfall - answerDirect precipitation to ground and precipitation striking and falling
off vegetation
Hyetograph - answergraph of precipitation over time
