Test results
Congratulations. You have passed the test and completed the 92 - Understanding our groundwater
Achieved badges:
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: 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: Is climate change a significant problem for our groundwater?
A: No
Q: Is climate change a significant problem for our groundwater?
A: Yes
Q: Is climate change a significant problem for our groundwater?
A: We won't know for 40 to 50 years
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: 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: 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
