Answer 11

1) Compressional force
2) sheer stress
3) tensional force

Question 12

TYPES OF FAULT:
Moves apart due to divergent plate boundary

Answer 12

Normal Fault

Question 13

TYPES OF FAULT:
This movement of blocks it’s parallel to the dip of the fault surface

Answer 13

Dip-Slip Fault

Question 14

TYPES OF FAULT:
Formed by compressional forces that pushes the plates towards each other

Answer 14

Reverse Fault

Question 15

TYPES OF FAULT:
Type of reverse fault whose dip is less than 45 degrees (45 ⁰)

Answer 15

Thrust Fault

Question 16

TYPES OF FAULT:
- Result of sideways movement of blocks of rocks
- Blocks move laterally
- Transform fault boundary

Answer 16

Strike Slip Fault

Question 17

TYPES OF FAULT:
- Combination of faults
- This sheer, tensional & compressional stress
