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)

The correct answer is: Seismic waves carry energy through Earth and shake Earth below the seismograph.
To understand how energy is transmitted to the seismograph, it is important to know what seismic waves are. Seismic waves are waves of energy that travel through the Earth's layers. They are generated by earthquakes, volcanic eruptions, and other seismic activities.
When an earthquake occurs, it releases energy in the form of seismic waves. These waves radiate outward from the source of the earthquake, traveling through the layers of the Earth. As these waves pass through the Earth's crust, they cause the ground to shake.
A seismograph is a device that is specifically designed to detect and record these ground vibrations caused by seismic waves. It consists of a suspended mass with a pen or needle attached to it. When the ground shakes, the mass moves along with it, while the pen or needle remains stationary on a strip of paper.
As the ground vibrates, the mass (also known as the seismometer) resists the movement due to inertia, causing the pen or needle to be dragged along the paper. This creates a graphical representation of the ground motion called a seismogram. The long flat line on the seismogram represents the absence of any ground motion, while the scribbles or spikes indicate periods of shaking caused by seismic waves.
In summary, seismic waves carry energy through the Earth and cause the ground to shake. This shaking is detected and recorded by a seismograph, which produces a seismogram that provides valuable information about earthquakes and other seismic activities.
