The Main Cause of Faulting is
The main cause of Faulting is Tension. A Fault is a break between two blocks of rocks in response to stress. Fault produce three type stresses. (a) Tension, (b) Compression, (c) Shear. Most earthquakes occur at plate margins due to tension, compression or shearing forces. Tension causes rocks to stretch and also break to produce a fault. Normal fault is produced by tensional forces.
