Question

Quizplus · Accepted Answer

The Richter scale is logarithmic, meaning that each increase of 1 on the scale represents a tenfold increase in intensity. Therefore, an earthquake that measures 6 on the Richter scale is 10x10x10 or 1,000 times more intense than an earthquake that measures 3. The Richter scale is logarithmic, which means that each increase of one unit represents a tenfold increase in the seismic waves' amplitude. Therefore, an earthquake that measures 6 on the Richter scale is 1000 times more intense (10 x 10 x 10) than an earthquake that measures 3 (which represents three units lower than 6). Therefore, the correct choice is D.
