physical weatheringPhysical weathering is caused when there are physical changes. For example the changes in temperature and even the effects of the wind, rain and waves. When a rock gets hot, it will expand and when a rock gets cold it contracts. After this happens the rock begins to crack. This example is called Onion Skin/ Exfoliation weathering. Weathering can also occur when it is exposed to the wind, rain and even waves. Wind can blow tiny parts of sand against a rock causing the rock to break apart slowly. Rain and waves can also wear away rocks if they contain more acid in them, they can wear away rocks fast however if they don't contain much acid it will still wear away rocks however slower.

(Picture above) This is an example of Chemical weathering which occurs when the rock itself is exposed to acidic rain.
