Question

1. removing too much water from aquifers can result in subsidence because the ______. aquifers close to the ocean will take in too much salt underlying rock is too solid air rushes in, causing an imbalance aquifers cant support the weight of overlying structures

Explanation:

Subsidence from over-pumping aquifers occurs because the water in aquifers provides buoyant support to the overlying rock and structures. When too much water is removed, the aquifer's pore pressure drops, and the aquifer materials can no longer bear the weight of the overlying layers, leading to sinking/subsidence. The other options are incorrect: saltwater intrusion is a separate issue, solid rock does not cause subsidence, and air rushing in is not related to this process.

Answer:

aquifers can't support the weight of overlying structures
