Answer to Question 1

Saved me massive time.

Answer to Question 2

Answer: Land subsidence can occur in areas underlain by thick sequences of poorly consolidated sediments. As water is pumped from an aquifer with layers of easily compressed waterbearing clays (low-permeability) interbedded with layers of sandy (high-permeability) rock, water slowly leaks out of the clay layers. As the clays become dewatered, they compact, and the land subsides.
