Test results
Congratulations. You have passed the test and completed the 92 - Understanding our groundwater
Achieved badges:
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
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: 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: 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
