The following image is a prediction of how an earthquake would spread from the epicenter (marked by a star). Red indicates the worst areas, and green indicates the places where there is the least shaking. Water is colored blue. Consider a seismic wave—an earthquake—that starts in the middle of the red area and travels outward along the surface of the earth. Image courtesy of U. S. Geological Survey Department of the Interior/USGS Point A is the same distance from the epicenter as point B. Using what you know about the movement of waves, how would you expect the seismic waves to be different at point A and point B? A. The waves would arrive at point B before they arrived at point A. B. The waves would be larger at point A than at point B. C. The waves would be exactly the same at points A and B. D. The ground would shake up and down at point A but back and forth at point B.
