The part of the ground in which pore spaces are completely filled with water is called the
A zone of aeration
B water table
C zone of saturation
D perched water table
3. Which statement is true about groundwater?
A Groundwater is stagnant and stays in one place until it is pumped upward for use.
B Groundwater is relatively young compared to Earth's surface water.
C Groundwater is in constant motion.
D Groundwater is buried so deeply that it is not considered part of Earth's water cycle.
4. Under what circumstances will a rock have high porosity but low permeability for groundwater flow? (Points : 3)
A the pores are formed by dissolution of limestone
B the pores are all interconnected
C the pores are very small
D the pores are very large
5. An unconfined aquifer is (Points : 3)
A enclosed within impermeable layers of rocks
B connected to the surface by open pore spaces through which water can flow
C a zone where water cannot flow
D a zone where water cannot be pumped upward for human use
6. Natural discharge of a groundwater system occurs when (Points : 3)
A rainwater percolates down through the soil
B the water table intersects the surface of the ground
C surface water seeps into the ground
D a confined aquifer is pumped for drinking water

True
False
8. What happens to the water in a confined aquifer if a well or fracture intersects it? (Points : 3)
A Its depth in the ground will sink downward.
B It may flow upward to produce an artesian well.

That's not help with science, it's cheating on home work.
It's only one simple chapter. Read it already.
You could probably have done it in the time it took you tp type in the questions.
