👉 Prepenetrating is a concept in geology and geophysics that describes how a rock or soil layer is exposed to the atmosphere before it reaches the surface. It is often associated with the process of weathering, which involves the removal of minerals from rocks through chemical reactions and physical processes such as erosion and weathering. In the context of prepenetrating, this means that when a rock or soil layer is exposed to the air during weathering, it is not fully covered by the
