Question

The magnitude of an earthquake is measured on:

(a) Celsius scale (b) Kelvin scale (c) Decibel scale (d) Richter scale

Open in App

Solution

Answer: (d) Richter scale
The Richter scale measures the magnitude of an earthquake (how powerful it is). It is measured using a machine called a seismometer which produces a seismograph. A Richter scale is normally numbered 1-10, though there is no upper limit.
