• The Climate: Climatic factors, like temperature and rainfall, affect the soil formation. In the areas of high rainfall and extreme temperature, rocks are easily weathered.

• The Vegetation Cover: At times, plants grow in the cracks existing in a rock. With time,roots of these plants start penetrating in the cracks and make them wider.
