Answer:

7. D. Tsunami

Explanation:

A tsunami is a wave of extraordinarily long waves created by a huge and rapid shift in the ocean bottom, which is generally caused by an earthquake beneath or near the ocean floor. This force generates waves that travel in all directions away from their source, spanning whole ocean basins in the process.

Answer:

8. A. In opposite directions to each other.

9. C. It can pass through solids only.

Explanation:

S waves don't move straight through the Earth. They only travel through solid material, and so are stopped at the liquid layer in the Earth's core.

Answer:

10. B. Liquid Outer Core

Explanation:

S-waves disappear at the mantle core boundary, so the outer core is liquid.

Answer:

11. C. Destructive

12. D. The speeds of seismic waves are affected by the material through which they travel.

13. D. Moment Magnitude Scale

14. A. Convergent
