Richter scale is used for measuring
A.
density of liquid
B.
humidity of air
C.
velocity of wind
D.
intensity of earthquakes
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
Richter scale is used for measuring intensity of earthquakes. The Richter scale measures the maximum amplitude of seismic waves as they reach seismographs. This scale is expressed with a logarithmic scale. Thus, an earthquake measuring 7.0 on the Richter scale would be 10 times larger than an earthquake that measures 6.0.
