Why do scientists use both the Richter and Mercalli Scales when determining earthquake magnitudes? Which do you find to be more accurate?
a) Because the Richter Scale measures the energy released by an earthquake while the Mercalli Scale measures the intensity of shaking
b) Because the Richter Scale measures the intensity of shaking while the Mercalli Scale measures the energy released by an earthquake
c) Because the Richter Scale measures both the energy released by an earthquake and the intensity of shaking
d) Because the Mercalli Scale measures both the energy released by an earthquake and the intensity of shaking
