Quizplus · Accepted Answer

When groundwater is withdrawn from an area underlain by unconsolidated sediments, the sediments compact and settle closer together, leading to ground subsidence. This is particularly common in urban areas where groundwater is heavily pumped for human consumption and industrial purposes. Ground subsidence rarely occurs in areas of karst topography or where consolidated sediments underlie the ground.
