What happens if groundwater is depleted too fast?
Why do people favour groundwater to surface water sources?
When bacteria in the soil interacts with organic compounds in the water, what are they broken down into?
Which conditions give water the best cleaning effect on the way to becoming groundwater?
What do we call the visible area from which the aquifer gets new water over time?
Test results
Congratulations. You have passed the test and completed the 92 - Understanding our groundwater
Achieved badges:
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: 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: 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: 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
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: 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
