Test results
Congratulations. You have passed the test and completed the 92 - Understanding our groundwater
Achieved badges:
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
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: 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: 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
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: Can iron be precipitated from water flowing down through the subsurface?
A: Yes
Q: Can iron be precipitated from water flowing down through the subsurface?
A: No
