Lithosphere - Folding and Faulting

Folding  When the rocks are subjected to horizontal compression forces, the rocks get folded . This is called Folding .
Causes of the folding-Folding occurs through compression.Folding is generally seen in mountain region.Folding often takes place in sedimentary rocks as they are more flexible as to compared to igneous or the metamorphic rocks.As a result of folding certain parts of the rocks are bent upward while the others are bent downward.The upfolds in the rocks are called anticlines while the downfolds are called synclines.In anticline, the rock strata inclines in opposite direction or away from common centre.In synclines, it bends towards a common centre.The upfold form fold mountain . E.g. Alps in Europe,  Himalaya in Asia , Andes of South America and Rockies in North America. The downloads form longitudinal valleys.
Types of folds :  The degree of compressional force leads ro different types of folds. The type,  shape and size of folds depends upon the intensity and direction …
