Front

What is the purpose of a seismograph?

Back

The purpose of a seismograph is to record the intensity and duration of seismic waves during an earthquake.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries.
