Final Jeopardy
Write a short paragraph that contrasts a magnitude 7.5 earthquake with a magnitude 2.5 earthquake. Be sure to discuss the energy released and the damage caused by each earthquake.
Sample: A 7.5 magnitude earthquake can cause large amounts of damage. It can bend railroad tracks and destroy many structures. A 7.5 magnitude earthquake releases 32 • 32 • 32 • 32 • 32, or about 33.5 million, times as much energy as a magnitude 2.5 earthquake. Magnitude 2.5 earthquakes might be noticed by some people but usually are detected only by seismographs.
