Question

JWhat produces a record of seismic waves?


barometer


Richter scale


seismograph


seismogram

Answer 1

A **seismograph** produces a record of seismic waves. It is an instrument that detects and records the motion of the ground caused by seismic waves as they travel through the Earth during an earthquake or other seismic events. The record produced by a seismograph is called a **seismogram**.

To clarify the other options:

- **Barometer** measures atmospheric pressure.
- **Richter scale** is a logarithmic scale used to quantify the amount of energy released by an earthquake, but it does not produce a record itself.
- **Seismogram** is the actual record produced by a seismograph.

So, the correct answer is **seismograph**.
