Journal of Earth Sciences Royal Dublin Society. Basal sapping occurs as water flowing around the rock layers of the mesa erodes the underlying soft shale layers, either as surface runoff from the mesa top or from groundwater moving through permeable overlying layers, which leads to slumping and flowage of the shale. This movement creates the tides of the oceans. 72. This became great news for the stability of our climate. This is your one-stop encyclopedia that has numerous frequently asked questions answered.
