Explain how changes in temperature affects the particles motion of a substance.

When you add heat energy to a substance, it gets stored in the form of the kinetic energy of the particles, and that means they move faster. Even if they don't go anywhere, like in a liquid or a solid, they still vibrate in their places, and when heat energy comes in, the particles vibrate faster.

When seismic waves hit a fault, the waves are reflected off the fault. seismograph can detect these reflected seismic waves. geologists then use these data to map the fault's length and depth
