-Folds are either anticlines or synclines.
-Many large hydrocarbon reservoirs occur within the cores of anticlines while adjacent synclines may contain the source of such material.
-Folds are curviplanar distortions of rock bodies. |

| When a stress is applied to an elastic material its response will vary dramatically from that of a plastic material. After unloading (i.e., removing an applied stress) an elastic material it will regain its original shape and volume. |

Structures that closely resemble planes are common features of the crust of planet Earth.
Examples include beds, joints, and faults. The attitude of a plane is expressed by its strike and dip. |
