Congratulations. You have passed the test and completed the 92 - Understanding our groundwater
Achieved badges:
Q: Can groundwater be over a thousand years old?
A: No
Q: Can groundwater be over a thousand years old?
A: Yes
Q: The rainwater which becomes new groundwater is called what?
A: Discharge
Q: The rainwater which becomes new groundwater is called what?
A: Replenish
Q: The rainwater which becomes new groundwater is called what?
A: Recharge
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: 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: How is a rising sea level a problem for coastal communities?
A: Because of saltwater intrusion into the coastal aquifers
Q: How is a rising sea level a problem for coastal communities?
A: It isn't - as long as the aquifer is healthy, there will always be enough pressure to hold back the seawater
Q: How is a rising sea level a problem for coastal communities?
A: It is actually a positive, because there will be greater pressure in wells further inland
