Question

explaining how earthquakes reveal earth’s interior
how do earthquakes help geologists understand earth’s interior?
during an earthquake, geologists use a machine called a to study seismic waves.
p waves can pass through both solid and molten rock, bu only through rock.
seismograph
drilling rig
magnetometer

Explanation:

To determine the machine used to study seismic waves during an earthquake:

• A seismograph is specifically designed to detect and record seismic waves (from earthquakes).
• A drilling rig is used for drilling, not studying seismic waves.
• A magnetometer measures magnetic fields, not seismic waves.

So the correct machine is a seismograph.

Answer:

seismograph
