Advertisements
Solution
| S. No. | Normal fault | Reverse fault |
| 1. | It results when a portion of land slides down along the fault plane. | It results when a portion of land is thrown upward relative to another side of the land. |
| 2. | The exposed portion of the plane faces the sky. | The fault plane faces the ground. |
| 3. | Form due to tensional stress. | Form due to compressive stress |
| 4. | The hanging wall is pulled apart from the footwall | The hanging wall is pushed towards the footwall |
| 5. | There is a downward meer of one side of the fault ul a to the other side | There is an upward movement of one side of the fault with respect to the other side |

Observe the diagrams and read the explanation regarding the characteristics of various faults given below. Identify the faults and match each of them with their characteristics.
A) Normal fault: It results when a portion of land slides down along the fault plane and when the exposed portion of the plane faces the sky.
B) Reverse fault: It results when a portion of the land is thrown upward relative to other side of the land. In such situation, the fault plane faces the ground.
C) Tear fault: At times, the rock strata on either sides of the fault plane do not have vertical displacement. Instead, movement occurs along the plane in horizontal direction.
D) Thrust fault: When the portion of the land on one side of the fault plane gets detached and moves over land on the other side. The angle of fault plane is generally lowless than 45°.
