What do we call the visible area from which the aquifer gets new water over time?
What do we call the water-bearing layer underground?
What happens if groundwater is depleted too fast?
Which conditions give water the best cleaning effect on the way to becoming groundwater?
Initially, water is driven underground by gravity. What is the main driver after a certain depth?

Q: Can technology help us find groundwater without digging bore holes?
A: Yes
Q: What do we call the visible area from which the aquifer gets new water over time?
A: Surface water source
Q: What do we call the visible area from which the aquifer gets new water over time?
A: The recharge area
Q: What do we call the visible area from which the aquifer gets new water over time?
A: The watershed
Q: What do we call the water-bearing layer underground?
A: An aquifer
Q: What do we call the water-bearing layer underground?
A: A water tank
Q: What do we call the water-bearing layer underground?
A: A well
Q: What happens if groundwater is depleted too fast?
A: The land subsides and a shallow lake forms
Q: What happens if groundwater is depleted too fast?
A: The land subsides and dries out
Q: What happens if groundwater is depleted too fast?
A: Water pressure drops, but in principle the aquifer is always there
Q: Which conditions give water the best cleaning effect on the way to becoming groundwater?
A: Fast travel time through the subsurface
Q: Which conditions give water the best cleaning effect on the way to becoming groundwater?
A: Slow travel time through the subsurface
Q: Which conditions give water the best cleaning effect on the way to becoming groundwater?
A: There is no cleaning effect through the subsurface
Q: Initially, water is driven underground by gravity. What is the main driver after a certain depth?
A: The main driver becomes pressure
Q: Initially, water is driven underground by gravity. What is the main driver after a certain depth?
A: The main driver is still gravity
Q: Initially, water is driven underground by gravity. What is the main driver after a certain depth?
A: Both pressure and gravity, depending on conditions
