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: 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: 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
