Question

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? [3 MARKS]

Answer 1

Each point: 1 Mark

1. The destructive energy of an earthquake is measured on Richter Scale.
2. The reading of magnitude 3 on the Richter scale would be recorded by a seismograph.
3. If the Richter scale gives a reading of magnitude 3, then the earthquake is not likely to cause much damage.
Generally, earthquake of magnitudes higher than 5 is considered destructive in nature.
