Question A granitic laccolith that formed 5 miles below the surface of the Earth has been uplifted by tectonic forces and now is exposed at the surface. The granitic rock of the laccolith is beginning to weather and has produced a series of cracks that are parallel to the surface. What is the cause of these cracks? gradient jointing The process of unloading A process called concentric weathering hydraulic fracturing
