Faulting and folding are both types of_? apex

Both can form simultaneously, even in the same place. There is an entire class of geometric models of fault-related folds. Fold bend folding and fault propagation ... Type of deformation depends upon the material characteristics

They are types of Geological structures.

Explanation:

Faulting creates Faults. A fault is a breakage or fracture of a rock where there is movement of a part of the rock relative to the other. Faults are examples of brittle structures. Folds are wave like structures formed in rocks. Folds are excellent examples of ductile structures.
