Is the Force that Squeezes rocks together, stretches or pulls them apart or pushes them in different Directions.

• Stress

• Compressive Stress

• Sheering Stress

The Different Types of Stress (Earthquakes)

A fracture in the rock where there has been movement and displacement. It lies at the Major Boundaries between Earth's Tectonic Plates, in the crust, and the earthquakes result from the plates movements.

• Faults

• Normal Fault

• Reverse Fault

• Strike-Slip Fault

Three Types of Faults are...

• Reverse

• Normal

• Strike-slip

• Faults

Called Lateral Faults because they happen along a horizontal plane parallel with the fault line as the plates slip by each other side by side.

• Strike-Slip Faults

• Normal Faults

• Reverse Faults

• None of the Above

They create spaces as the two blocks of crust pull apart

stretching the crust into a valley.

• Strike-Slip Faults

• Normal Faults

• Reverse Faults

• None of the Above

Are created from Horizontal Compression or contracting of Earth's Crust.

• Strike-Slip Faults

• Normal Faults

• Reverse Faults

• None of the Above

The Origin of an Earthquake is...

• Faults

• Focus

• Stress

• None of the Above
