Friedhelm von Blanckenburg
Weathering of rock needs water. A rock fractured by tectonic movement is gradually eroded from above, and it moves closer towards the Earth's surface. There it is exposed to precipitation and water begins to penetrate the soil and the layers beneath the soil. Through the tectonic fractures, the water can reach great depths.
