10. 
    Weathering
    the breakdown of rocks and minerals at and just below the Earth's surface caused by a number of physical and chemical processes. Physical or mechanical weathering is caused by atmospherically controlled processes such as temperature or humidity changes. Many of these processes are due to crystal growth - for example ice growth and expansion in freeze-thaw action, or the growth of salt crystals in salt weathering. Physical weathering does not involve chemical changes to rock. Chemical weathering is caused by decomposition of rocks making them more sensitive to erosion. This includes the effects of acid rain on limestones, or the decomposition of granite to clay. Physical and chemical weathering processes work together to disintegrate rocks

    Weathering
    `Weathering` is the decomposition of rocks, soils and their minerals through direct contact with the Earth's atmosphere. Weathering occurs `in situ`, or `with no movement`, and thus should not to be confused with erosion, which involves the movement and disintegration of rocks and minerals by agents such as water, ice, wind and gravity. Two important classifications of weathering processes exist. `Mechanical` or `physical` weathering involves th...
