1 Interactive map

2 Earth’s Crust in Motion Section 5-1

3 Earthquake Shaking that results from rock movement below Earth’s surface

4 Stress

5 Force that acts on Earth’s crust to change its shape or volume

6 3 kinds of stress 1.Shearing One rock, Two directions.

7 3 kinds of stress 2.Tension Stretches rock

8 3 kinds of stress 3.Compression Squeezes rock

9 Let’s Review!!!

10 Fault Break in rock Caused by stress Slabs of crust slip past each other Usually occur at plate boundaries

11 3 kinds of FAULTS 1.Shearing → Strike-slip faults Slip past sideways, no vertical motion “Transform boundary” at plate boundaries

12 Strike-Slip Fault

16 3 kinds of FAULTS 2.Tension → Normal faults At an angle Above fault = Hanging Wall (slips down↓↓) Below Fault = Footwall

17 Normal Fault

20 3 kinds of FAULTS 3.Compression → Reverse faults At an angle Hanging Wall (slips up↑↑↑)

21 Reverse Fault
