Question

Earthquakes can be recorded on a seismograph. This device produces a piece of paper with a long flat line, along with scribbles drawn with a needle that represent times when there has been an earthquake. How is energy transmitted to the seismograph?(1 point)
Responses

Seismic waves carry energy through the air and shake the needle of the seismograph.
Seismic waves carry energy through the air and shake the needle of the seismograph.

Seismic waves carry energy through Earth and shake Earth below the seismograph.
Seismic waves carry energy through Earth and shake Earth below the seismograph.

Sound waves carry energy through the air and shake the needle of the seismograph.
Sound waves carry energy through the air and shake the needle of the seismograph.

Sound waves carry energy through Earth and shake Earth below the seismograph.

Answer 1

Seismic waves carry energy through Earth and shake the ground beneath the seismograph.
They move the ground (and the seismograph frame), causing relative motion recorded as the needle’s scribbles.
