Yes
3: Is climate change a significant problem for our groundwater?
We won't know for 40 to 50 years
4: What happens if groundwater is depleted too fast?
The land subsides and a shallow lake forms

4: What happens if groundwater is depleted too fast?
The land subsides and dries out
4: What happens if groundwater is depleted too fast?
Water pressure drops, but in principle the aquifer is always there

5: How is a rising sea level a problem for coastal communities?
Because of saltwater intrusion into the coastal aquifers
5: How is a rising sea level a problem for coastal communities?
It isn't - as long as the aquifer is healthy, there will always be enough pressure to hold back the seawater
5: How is a rising sea level a problem for coastal communities?
It is actually a positive, because there will be greater pressure in wells further inland
6: What do we call the water-bearing layer underground?
An aquifer
