Tension is when the earth's crust gets pulled on by stress. Which slowly stretches the rock apart. It happens when multiple plates move.
Shearing is caused by stress with such a strength that move the mass of rock in opposite directions. Which overtime can cause rock to break of slip. Changing the shape of the plate.
Types of Stress Shearing
Types of Stress Compression
Compression is when stress pulls the rocks together and makes them fold or break apart.
Faults Strike Slip
A strike-slip fault is caused by shearing. In a strike-slip fault, the rocks on either side slide past each other sideways and with little upward or downward force.
A normal fault is caused by tension. In a normal fault, the fault is at an angle, the masses of rock are on top of one another. The mass of rock above is called a hanging wall and the mass below is called the footwall
A reverse fault is powered by compression. A reverse fault is almost the same as a normal fault but masses of rocks move toward each other instead of away from each other. Reverse faults make mountains. In a reverse faults the rock moves on top of each other
