Weathering
. In the UK, west-facing stones are usually more weathered than east-facing stones, because winds from the west are warmer and moister, whereas east winds are typically colder and drier. Rock type is also important: igneous and metamorphic rocks, such as granite and marble, weather more slowly than sedimentary rocks, such as limestone.', copy:'(Image © Garret Nagle)'});)

Process by which exposed rocks are broken down on the spot (in situ) by the action of rain, frost, wind, and other elements of the weather. It differs from erosion in that no movement or transportion of the broken-down material takes place. Two types of weathering are recognized: physical (or mechanical) weathering and chemical weathering. They usually occur together, and are an important part of the development of landforms.
