what percent of water on earth is salt water
97%
what percent of water on earth is fresh water
3%
where is the majority of fresh water found
in glaciers
where is the smaller percentage of freshwater found
rivers lakes and ground water
what is precipitation
when water vapor cools and condenses
rain
what is run off
water running off land surfaces
what is infiltration
the Processes by witch water becomes ground water below the serface
what is transpiration
when plants release release water vapor into the atmosphere through their leaves
what is condensation
where water vapor Collide and become a water droplet
what is the water cycle
water on land then goes into the atmosphere then returns back to land
what is an unsaturated zone for groundwater storage
pores area where water can easy pass through
what is a saturated zone for ground water storage
where water compleatly fills pore space
what is a water table
upper layer of the saturated zone
what dose it mean if sediment is permeable
how easy the water passes through
more permeable = water passes through easly
what us an aquifer
a rock unit that can transfer water through its poor space
what is the name of the great plains aquifer
ogallala aquifer

what is an aquitarde
keep water confined
how are water springs formed
where a water table natural meats the surface
what is an artesian well
when we drill into an pressurized aquifer
what is a cone of depression
the direction the water flows in direction down the well
absolute dateining
assigning an exact date (numeral age ) to an orgnizium
relative dating
putting things in proper order in time
uniformiarianisim
states that laws of nature operate the same today as they have in the past
principles of superposition
states that in an undisturbed sequence of sedimentary rock layers from youngest to oldest
uniformity
gaps in the rock record during the during witch either erosion occurring or deposition was absent
fossil
the remains or tracing of and orgnizium found in rock
