Answer the following question given this paragraph: Richter scale magnitudes jump from one level to the next. The height of the largest wave increases 10 times with each level. So the height of the largest seismic wave of a magnitude 5 quake is 10 times that of a magnitude 4 quake. A magnitude 5 is 100 times that of a magnitude 3 quake. With each level, thirty times more energy is released. A difference of two levels on the Richter scale equals 900 times more released energy. Q: How many times does the height of the largest wave increase with each level? A:

OPT: -- 20 times -- 100 times -- 5 times -- 10 times
Answer:
10 times
