Unlike body waves, surface waves (also known as long waves, or simply L waves) move along the surface of the Earth. Surface waves are to blame for most of an earthquake's carnage. They move up and down the surface of the Earth, rocking the foundations of man-made structures. Surface waves are the slowest moving of all waves, which means they arrive the last.
Correct Answer: [None] Response Feedback: ï· Question 10 4 out of 10 points When you are at the beach, you notice that the waves seem to break at the same point as they come towards shore. Explain what is happening beneath the surface to cause the waves to break at this point. Selected Answer: Breakers form when orbital particle motion at the trough of the wave slows more rapidly than at the crest. The water at the crest of the wave will move forward and outrun the base of the wave.
