A seismograph1 pointA) Measures the strength of a volcanoB) Measures the strength of an earthquakeC) Measures the amount of continental drift

Break Down the Problem

1. Understand the function of a seismograph.
2. Analyze each option to determine which one aligns with the seismograph's purpose.

Relevant Concepts

A seismograph is an instrument used in geology to measure seismic waves produced by earthquakes. It records the motion of the ground as a function of time.

Analysis and Detail

1. Option A: Measures the strength of a volcano

   • A seismograph does not specifically measure volcanic activity; it primarily records seismic waves caused by earthquakes.

2. Option B: Measures the strength of an earthquake

   • This is the correct function of a seismograph. It detects and records the vibrations caused by seismic events.

3. Option C: Measures the amount of continental drift

   • Although seismographs can be useful in studying tectonic activity related to continental drift, they do not directly measure the drift itself.

Verify and Summarize

Upon reviewing the options, it is evident that the primary function of a seismograph is to measure seismic activity, which directly correlates to earthquakes.

Final Answer

B) Measures the strength of an earthquake is the correct answer.
