Faults and Stress Unit 2 Lesson 2

Faults  Fractures in the earth occur when a force is applied to the underlying rock, which movement occurs.  Stress is the force per unit area acting upon a material.  There are 3 types of stress that acts upon the Earth’s rocks:  Compression: decreases material volume  Tension: pulls the material apart  Shear: Causes the material to slip or twist

Types of Faults  Slip Faults  Horizontal tension  Sideways movement  Normal Fault  Tension (Apart)  Down on advancing block   Thrust/Reverse Fault  Compression  Uplift of advancing block

Examples of Faults  Reverse Fault  Note the compression  Note the uplift  San Andreas Fault  Pulled apart  Sideways movement
