Where does the water come from?
Aquifers
Aquifer: here Underground deposits of sand, gravel, or rock saturated with water.
Porous rock: Can absorb water, much like a sponge, as it has tiny holes in it. Chalk is a
good example.London is built on sand and gravel, but underneath this
is a thick layer of chalkOver thousands of years, the rain that fell in London
collected in this chalk.We can now drill through the sand and gravel and pump
the water from the aquifer.On p146 is a diagram of the London Basin, copy this
diagram and explain where and how we obtain our water.
