Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What device measures the strength of an earthquake?
A
seismograph
B
barometer
C
anemometer
D
None of the above
Explanation: 

Detailed explanation-1: -A seismometer is the internal part of the seismograph, which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with “seismograph". Seismographs are instruments used to record the motion of the ground during an earthquake.

Detailed explanation-2: -The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included for the variation in the distance between the various seismographs and the epicenter of the earthquakes.

Detailed explanation-3: -seismograph, instrument that makes a record of seismic waves caused by an earthquake, explosion, or other Earth-shaking phenomenon.

Detailed explanation-4: -A device called a seismograph can be used to measure the magnitude of any earthquake.

Detailed explanation-5: -The Richter scale is used to rate the magnitude of an earthquake, that is the amount of energy released during an earthquake. On the other hand, a seismograph is an instrument used to detect and record seismic waves.
