An earthquake with a magnitude of about 2.0 or less is called a microearthquake. It is not usually felt. The intensity of an earthquake with a magnitude of 2 is how many times greater than the intensity of an a standard earthquake?
A
2 times greaterB
10 times greaterC
100 times greaterD
1,000 times greater13
What is the intensity of an earthquake with a magnitude of 3?
A
3 times a standard earthquakeB
100 times a standard earthquakeC
1,000 times a standard earthquakeD
3,000 times a standard earthquakeE
30,000 times a standard earthquake16
How many more times intense is an earthquake that measures 8 on the Richter scale than an earthquake that measures 5? Explain your answer.
Answer:
A magnitude 8 earthquake is 1,000 times more intense than a magnitude 5 earthquake because 10^(8-5) = 10^3 = 1,000.

Which did you include in your answer?
A
A magnitude 8 earthquake is 1,000 times more intense than a magnitude 5 earthquake.B
A magnitude 8 earthquake is 108 times more intense than a standard earthquake, while a magnitude 5 earthquake is 105 times more intense than a standard earthquake, and 108 ÷ 105 = 103.C
Each unit increase on the Richter scale corresponds to an intensity increase by a factor of 10. So from 5 to 8 on the Richter scale, the intensity increases by 103 = 1,000Did you find these answers helpful?
