In folding, because the compressional forces act from two opposite sides towards the centre, the land in the centre rises in a series of folds. There are various types of folds. These are
Types of Folds
Symmetrical folds: When two compressional forces act from two opposite directions, gentle and simple folds are formed which are known as symmetrical folds.
Asymmetrical folds: When the compressional force is intensive from one side, one limb becomes steeper than the other, and the folds which are formed are known as asymmetrical folds.
Recumbent fold: When the fold is pushed further, the limbs get placed in a horizontal position known as a recumbent fold.
Overthrust fold: When one side of a fold slides past the other side of the fracture or fault, it is known as an overthrust fold.
Fan-shaped fold: Sometimes, small arches are formed when the compressional forces act from opposite sides. Under such circumstances, many fan-shaped folds which resemble a fan are formed.
Folding and Faulting
Orogenic Processes include mountain building through severe folding and faulting. In folding, because the compressional forces act from two opposite sides towards the centre. Read more
Rocks play an important role in the formation of soil. Soil is formed because of weathering and decomposition of rocks. Rocks also contain many minerals. Read more
