Detailed explanation-1: -When two forces act towards each other from opposite sides, rock layers are bent into folds. How folds are formed due to compression is known as folding. Folding is one of the endogenetic processes; it takes place within the Earth’s crust. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds.

Detailed explanation-2: -Folding-Folding occurs when tectonic processes put stress on a rock, and the rock bends, instead of breaking. This can create a variety of landforms as the surfaces of the folded rocks are eroded. Anticlines are folds shaped like an arch, and synclines are shaped like the letter ‘U. ‘

Detailed explanation-3: -BENDING FOLDS. BENDING FOLDS. In contrast to buckling in which case folds are generated as periodic waveforms when compression is applied parallel or at small angle (<45 degrees) to the layer boundaries.

Detailed explanation-4: -The movement of the Earth’s plates leads to rocks being compressed into each other, and this in turn leads to the formation of folds and faults. Folds form when the layers of rock bend around, and faults occur where rock layers actually break, and in some cases slide over each other.

Detailed explanation-5: -Figure 10.9: Folds are a result of ductile deformation of rocks in response to external forces.
