temperature. Weathering occurs in place (in situ). Weathering is the event that comes before the action of erosion. Weathering is responsible for many wonderful landforms usually seen in coastal areas.<\/span><\/p><p><span data-preserver-spaces=\"true\">In Australia, great natural icons such as Uluru (Ayers Rock), the Twelve Apostles, and Karlwekarlwe (The Devil\u2019s Marbles), as well as the Grand Canyon in the USA, glacial landscapes in Europe, and the huge dune fields of the Sahara Desert in Africa are all examples of weathering and erosion in action.<\/span><\/p><h3><span data-preserver-spaces=\"true\"><b>Erosion, or Weathering?<\/b><\/span><\/h3><p><span data-preserver-spaces=\"true\">It is important not to confuse erosion with weathering. The difference is, weathering determines what can be eroded. It is the breakdown of the rock itself. Erosion is when the weathered material is transported to another place by water, wind, or ice. Erosion produces landforms that are often tall and jagged, but deposition usually produces landforms on flat, low land.<\/span><\/p><p><span data-preserver-spaces=\"true\">Weathering is considered a destructive process in landform formation. The extent of weathering often depends on the makeup of the land, time, and climate (water, wind, and temperature)<\/span><\/p><h3><span data-preserver-spaces=\"true\"><b>Types of Weathering<\/b><\/span><\/h3><p><span data-preserver-spaces=\"true\">There are three types of weathering \u2014 Physical, Chemical, and Biological.
