parts of water cycle
Definition
evaperation, condinsation, percipation, transperation, ground water, sink, watershed, aquifer
Term
aquafer
Definition
porous calicium limestone which filters ground water and returns it to discharge areas called springs
Term
wetlands
Definition
any one of several ecosystems in which the sink of the area holds water above the ground
Term
barier island
Definition
product of longshore drift which gives added protection from surge
Term
storm surge and effects
Definition
floods and washes away coastline, if area is below sea level water becomes blocked inland causing further distruction
Term
dredging
Definition
the digging of a channel off the coast to allow for watercraft travel
Term
erosion and its effects on coast
Definition
erosion strips away coast and efferts must be made to limit its effects for multiple reasons, ecosystems, tourisim, organisms in that ecosystems
Term
estuary
Definition
salt and fresh water mix very diverse populations and spurs many ecosystems
Term
sea walls benifets and probloms
Definition
benifet-reduce erosion, reduce runnoff
probloms- reduce coast, hinders natural ecosystems
Term
what are natural buffer to erosion
Definition
mangrove red black and white, , oysterbeds, cypress trees, and barier islands
Term
water shed
Definition
natural recharge area for the aquifer many times the lowest point of the watershed is a sinkhole
Term
turbidity
Definition
suspended particles in water making it cloady
Term
types of wetlands
Definition
1. bog
2. salt marsh
3. mud flats
4. mangrove forest
Term
what can wetlands prevent by being a buffering zone for nitrogen, phosphrousand various runnoff things
Definition
dead zones
Term
watershed
Definition
a single recharge area for aquifer over thousands of aceres
Term
percentage of earth covered in water
Definition
70%
Term
types of bonds
Definition
ionic
matalic
covalient
Term
the unique attractive ability of water to attract other water mollicules and what causes it
Definition
adhesion principle created by polar principle of water
Term
the ability for water to attract other molicules like salt
Definition
cohesion
Term
viscosity
Definition
the thickness of a fluid
Term
heat capacity
Definition
the heat at which a substance changes temperature
Term
latent heat
Definition
the ability for some substances to change phases before they reach their heat capacity becouse of fast changes
Term
formula for density
Definition
d=m/v
Term
explain why ice a solid of water will float on liquid water
Definition
the solid as latent heat decreases crystalyze taking up more space while keeping mass the same therefore reducing density
Term
a layer at apx 33 feet which reduces temperature up to 20 degrees
Definition
thermocline
Term
boyancy
Definition
the ability to displace more weight then somthing it weighs in a fluid based upon archmedes principle
Term
example and working deffination of a mixture and a solution
Definition
solution- cool aid two seperate substances mix completly making then hard to seperate
mixture-milk two or more substances sit suspended by one another but do not mix completly
Term
why is salt a unique substance expecially as it applies to water
Definition
Na- sodium explodes when added to water
Cl- green poisoness gas which kills all life forms
but when combined make a harmless substance
Term
parts of water cycle
Definition
1. percipitation
2. condinsation
3. evaperation
4. transperation
5. ground water
6. runnoff
7. water shed
Term
what are some unique properties of water which make it unique and set the stage for all life on our planet
Definition
1. conducts electricity
2. decrease heat capacity
3. raised boiling point
4. decreased freezing temp
5. slowed evaperation
6. create osmotic pressure
Term
principle of law of pressure temperature and density
Definition
boyal, the deeper the water the colder it is the more pressure there is and the more dence the water is
Term
deepest color spectrum
Definition
blue
Term
shallowest color spectrum
Definition
red
Term
the speed of sound when compared to light in water
Definition
sound is faster in water therefore the speed of the light and sound are apx the same speed
Term
ph of normal fresh water
ph of salt water
Definition
7, 8
Term
osmosis
Definition
water going through semipermiable membrane
Term
diffusion
Definition
spreading from high concentration to low concentration
Term
delta
Definition
fan shaped deposit of debris in an estuary
Term
eutraphacation
Definition
out of control algea growth in areas where there is too much nutrients
Term
process of eutrophacation
Definition
1. excess nutrients
2. phytoplankton bloom
3. die off
4. hypoxia
Term
what is hypoxia
Definition
the growth of algea to the point at which oxygen is removed from water during night phase of photosysnthesis
Term
point pollution
Definition
a direct sourse of a polutant
Term
nonpoint pollution
Definition
pollution sourse is untracable
Term
surface tension
Definition
the effect of hydrogen bonding allowing for boyancy
