Question

Folding and faulting of strata is caused by

1. Volcanic activities
2. Earthquake
3. Movement of plates
4. Weathering and erosion

Answer 1

Answer:

Fault-bend folds are caused by displacement along a non-planar fault. In non-vertical faults, the hanging-wall deforms to accommodate the mismatch across the fault as displacement progresses. Fault bend folds occur in both extensional and thrust faulting. ... Displacement over this higher-angle ramp generates the folding
