Answer:
9. The kinetic energy
3. Volcanic eruptions
7. D.Plate Boundary
Answer:
9.kinetic energy
3.volcanic eruption
7.titonic plate
Explanation:
9.The kinetic energy (energy of motion) of the disturbance radiates in all directions away from the focus in the form of waves. ... Most of the kinetic energy of an earthquake is released in the form of surface waves.
3.Volcanic eruptions are direct sources of information about the interior of the earth. ... As and when the molten material (magma) is thrown onto the surface of the earth, during a volcanic eruption it becomes available for laboratory analysis.
7.Tectonic plate interactions are classified into three basic types: Divergent boundaries are areas where plates move away from each other, forming either mid-ocean ridges or rift valleys. These are also known as constructive boundaries. Convergent boundaries are areas where plates move toward each other and collide.
