Water above Earth's surface
surface water
the path that a stream follows
what is used to calculate a stream discharge
the volume of water that flows over time
how might a raindrop could become surface then groundwater, then end up back up on Earth's surface again
rain falls into rivers, seeps into the ground then evaporates back up onto the earth's surface.
The water found in the spaces between rock particles below Earth's surface
groundwater
the area of land that is drained by a river system
water shed
What would increase the effect of erosion in a watershed?
higher gradient/ steep slope
What are the 3 factors that describe the movement of surface water in streams and rivers? Explain each
Gradient-steepness of the river
flow- the flow of the river
stream load- Materials carried by the rivere
in the upper boundary, or surface, of groundwater
water table
is a body of rock or sediment that stores groundwater and allows it to flow
an aquifer
What is the name for all the materials carried by a stream other than the water itself?
stream
How does permeability relate to the usefulness of an aquifer?
permeability is a measure of how easily water can flow through an aquifer. A useful aquifer will have a high permeability
is a smaller stream that feeds into a river and eventually into a river system
tribuatary
What is a measure of the amount of open spaces between the particles of rock and soil?
porosity
the groundwater in a certain area is being pumped out to provide drinking water. What must happen for the water table to remain
the rate of discharge must equal the rate of recharge
watersheds are separated from one other by a ridge or an area of higher ground
divide
what is an incorrect statement about the flow of water through watersheds?
plant life often alters the flow of water in a watershed by causing erosion
