Question

A seismograph is also known as:
A) Seismogram
B) Seismology
C) Seismometer
D) Seismicity

Answer 1

Hint: A seismograph is an instrument which measures and keeps record of the seismic waves. And the instruments that measure some parameters are meters. So the seismometers are also considered as the instrument that measures seismic waves.

Complete step by step answer:
A seismograph is also known as seismometer. This is the instrument which is used to measure and keep records of the seismic waves. Seismic waves are the waves of energy that travels through the layers of the earth which results in earthquakes. The study of seismic waves is called seismology. Whereas the seismogram is a record written by a seismograph measured with the help of seismometers.

These devices are used in those regions which are prone to earthquakes. These instruments also help to predict the occurrence of earthquakes. But the prediction is not before much time. There are generally 4 types of seismic waves namely Primary, secondary, surface and Rayleigh waves. Different waves have different intensity.

Note: There is very less difference between all these terms. The seismograph is known as a seismometer which is an instrument. Whereas seismology is the study of seismic waves and seismogram is the record written in seismographs.
