What instrument records earthquake waves? A.) seismogram B.)

Yes, B.

Thanks

The instrument that records earthquake waves is a seismograph (Option B). To determine the correct answer, you can break down the question and analyze each option:

A) Seismogram: A seismogram is not an instrument but a graphical representation of the earthquake waves recorded by a seismograph. It is like a visual output or a paper printout of the seismic data.

B) Seismograph: A seismograph is the correct answer. It is an instrument used to detect and record the vibrations caused by earthquakes. It consists of a seismometer, which is a sensor that senses ground motion, coupled with a recording mechanism like a pen or a digital system to record this motion on a chart or in digital format.

C) Richter scale: The Richter scale is not an instrument but a logarithmic scale used to quantify the magnitude of an earthquake. It assigns a numerical value to represent the strength or energy released by an earthquake.

D) Barometer: A barometer is an instrument used to measure atmospheric pressure, not earthquake waves.

By considering the options and understanding their roles, you can determine that the correct instrument for recording earthquake waves is a seismograph.
