Q.6 Name the scale on which the destructive energy of an earthquake is measured. An earthquake measures 3 on this scale. Would it be recorded by a seismograph? Is it likely to cause much damage?

The destructive energy of an earthquake is measured by the Richter scale.

This scale has readings from 1 to 10.

Seismograph can measure an earthquake of magnitude 3 on the Richter scale.

If the Richter scale gives a reading of magnitude 3, then the earthquake is not likely to cause much damage. Generally, earthquakes of magnitude, higher than 5 is considered destructive in nature.
