Test results
Congratulations. You have passed the test and completed the 92 - Understanding our groundwater
Achieved badges:
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: 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
Q: Can technology help us find groundwater without digging bore holes?
A: No
Q: Can technology help us find groundwater without digging bore holes?
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: When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
A: Pollutants in the water
Q: When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
A: Nothing - this process happens on the surface
Q: When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
A: Pure water and CO2
