What does bends and folds in rocks show?

Bends and folds in rocks indicate that the rocks have undergone significant stress and deformation, typically due to tectonic forces. These structures often reveal the history of geological processes, such as plate tectonics and continental collisions. The orientation and type of folds can provide insights into the conditions of pressure and temperature at which the rocks were formed and altered. Additionally, they can help geologists identify potential resources like oil and gas, as well as assess earthquake risks in the region.
