Answer:

6. B.

7. A.

Explanation:

6. Strike-slip Fault - forms when the movement is parallel to the fracture with side-to-side motion. The slip causes a sudden shaking or vibration in the Earth due to the sudden release of energy from within the Earth. The higher the stress, the greater the energy released.

7. Movement of the fault causes a release in energy. As the energy passes through an area, the vibration is felt. The energy is then transferred through the Earth and man-made structures. The bigger the amount of slip, the more vibrations are produced.
