Centuries ago quarrymen learned that when quarrying granite it was usually easiest to break the rock along a nearly horizontal surface. We now know this arises because ________.
◦ it was a false observation; the quarrymen in those days couldn't measure resistance, and it just seemed easier to wedge blocks of this type
◦ chemical weathering of granite makes the material expand, pulling it away from the underlying rock
◦ uplift and exhumation of granites produces an unloading, which produces sheeting joints like the quarrymen used
◦ frost wedging for hundreds of thousands to millions of years have produced cracks parallel to the ground surface
