Water table is lowered when ______ activity increases.
Open in App
Solution
The correct option is B Mining
Water table
is lowered when mining activity increases because the water table is an
underground boundary between the soil surface and the area
where groundwater saturates spaces between sediments and cracks in the rock. Water force and atmospheric force are equal at this boundary. Heavy
rains or melting snow may reason
the water table to rise, or heavy pumping of groundwater supplies may cause the water table to fall.
Thus, the correct option is A.
