How much greater is the shaking produced by a magnitude 8 earthquake than a magnitude 5 earthquake using the richter scale?
a. 10,000 times greater
b. 100 times greater
c. 3,000 times greater
d. 1,000 times greater

The shaking produced by a magnitude 8 earthquake is 3000 times greater than a magnitude 5 earthquake using a Richter scale. The answer is letter C. As the number in the Richter scale increases, the magnitude of earthquake also increases.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
