Which branch of science deals with the study of earthquakes?
- A.Seismology
- B.Volcanology
- C.Speleology
- D.Geodesy
Correct answer
Explanation
The correct answer is A, seismology. Seismology is the study of earthquakes and of the passage of seismic waves through the earth, and it is from seismic wave records that the layered structure of the interior of the earth has been worked out; the instrument used is the seismograph. Option B is wrong because volcanology is the study of volcanoes, their eruptions and their products, which is a related but separate branch. Option C is wrong because speleology is the study of caves. Option D is wrong because geodesy is the science of measuring the shape, size and gravity field of the earth, the basis of surveying and of map making. Note that the study of the earth's crust and rocks as a whole is geology. The Richter scale measures the magnitude of an earthquake and the Mercalli scale its intensity, and both names are asked in the same breath as seismology.
