Question

The intensity of the earthquake is measured on the_______________?
A. Righter scale
B. Richter scale
C. Seismic scale
D. None of the above

Answer 1

Hint: It is a standard scale. It is a logarithmic scale which measures a factor of 10. It is measured by using information gathered by seismograph. It has base 10 logarithmic scale. By this information you can guess the scale.

Complete Step-by-Step solution:
The intensity of earthquakes is measured on the Richter scale. It is a device which compares earthquakes. Whenever an earthquake comes, we can measure the intensity of it by using the Richter scale. An intensity of earthquake is measured or guessed by two things: first is amplitude and the other one is energy. Then what is amplitude? You will usually see waves while recording on phone or while playing radio. These waves not only produce when sound plays, basically it occurs when transfer of energy has been done. It has a base10 logarithm. Therefore at every 1.0 points, the scale increases 10 fold because of logarithmic basis. Basically it measures how much amplitude a wave has, how much energy it has produced and how much force it is applying.

Additional information:
The Richter scale was invented in the 1930s to give some understanding to the magnitude and intensity of a quake as measured by seismographs; ground monitoring equipment.
Correct option is (B)

Note: Students may get confused in option A and B because of spelling. Note down the spelling of Richter carefully. Option C is related to earthquakes, but it’s an seismic wave which is produced during earthquakes.
