5: What happens if groundwater is depleted too fast?
The land subsides and dries out
5: What happens if groundwater is depleted too fast?
Water pressure drops, but in principle the aquifer is always there

6: Initially, water is driven underground by gravity. What is the main driver after a certain depth?
The main driver becomes pressure
6: Initially, water is driven underground by gravity. What is the main driver after a certain depth?
The main driver is still gravity
