Next climate. vine one of the most important factors influencing wine quality. The different types of soil have evolved in millions of years through physical and chemical weathering of rocks as well as humification of organic matter (see also under geology ). During physical weathering, forces of nature such as wind, water, heat, cold and ice first cause the mechanical fragmentation of rock formations into pebbles and gravel. Strong temperature differences, frictional and shear forces as well as frost damage caused by frozen water play an important role in rock fissures. Chemical weathering processes like oxidation, Solution processes and acid attacks attack the mineral lattice structure of the rocks. This easily water-soluble minerals such as carbonates and Sulfate first dissolved, the rock slowly decays to grus, sand, silt or clay. Any rock, even the hardest granite or quartz will eventually crumble to dust, even if it takes millions of millions of years.
