Degree of rock weathering
WebJan 1, 1976 · In temperate and particularly tropical zones, a warm and humid climate supports deep-reaching chemical weathering, which results in chemical decomposition of rock components. If climatic conditions of a given area remain unchanged for a long time, a typical profile through the weathered layer develops near the surface. WebWeathering is the process that changes solid rock into sediments. Sediments were described in the Rocks chapter. With weathering, rock is disintegrated. It breaks into pieces. Once these sediments are separated …
