Answer:
seismograph can be used to detect hidden faults.
Step-by-step explanation:
- A seismometer is used to detect the seismic waves.
- It used to find out detect the hidden faults.
It detects motions that occur at the ground level, like volcanic eruptions, earthquakes. It when used along with a timing device,seismograph is formed. The data which is obtained used to study the internal structure of the Earth.
A seismograph is used to find the seismic waves when an earthquake occurs, by detecting the reflection which occurs due to the seismic waves, the scientist can detect the hidden faults.
Thus this how seismograph can be used to detect hidden faults.
