Faults are "locked" because . major faults occur at plate boundaries that only move occasionally high confining pressure increases friction on the fault elastic rebound occurs on faults earthquakes only form when the rocks are free to move otherwise they would have earthquakes all the time

high confining pressure increases friction on the fault

Explanation:

Faults are "locked" because high confining pressure increases friction on the fault.

A. high confining pressure increases friction on the fault

Explanation: A Fault is a line or zone between two rocks, which are caused by certain earth Movement.

A fault is a also known as fractures or cracks seen on the earth crust, within this faults there are some kinds of compressional movement s and tensions taking place.

WHEN THE CONFINING PRESSURE IS HIGH,THE FRICTION ON THE FAULT INCREASES.
