Test results
Congratulations. You have passed the test and completed the 92 - Understanding our groundwater
Achieved badges:
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: Why do people favour groundwater to surface water sources?
A: Access to surface water is often limited for many due to land ownership
Q: Why do people favour groundwater to surface water sources?
A: They don't - lakes and rivers provide a much more reliable supply
Q: Why do people favour groundwater to surface water sources?
A: The cleaning effect from filtration through the subsurface makes groundwater much safer
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: Can groundwater be over a thousand years old?
A: No
Q: Can groundwater be over a thousand years old?
A: Yes
Q: Can you spread the load on an aquifer by extracting from more wells distributed over a wider area?
A: Yes
Q: Can you spread the load on an aquifer by extracting from more wells distributed over a wider area?
A: No
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
