Understanding Seismographs and Earthquakes

The video tutorial explains how earthquakes are measured using a seismograph. It describes the seismograph's ability to measure horizontal and vertical movements, as well as the duration and intensity of earthquakes. The video also details the components of a seismograph, including a heavy base, a frame, a wire, a weight, a pen, and a rotating paper drum. When the ground shakes, the pen records a trace called a seismogram. Viewers are encouraged to watch the full video for more information.

What does a seismograph measure during an earthquake?

• Only the horizontal movement

• Only the vertical movement

• Both horizontal and vertical movements, along with duration and intensity

• Only the duration of the earthquake

Which component of a seismograph is responsible for drawing the seismogram?

• The heavy base

• The rotating paper drum

• The frame that holds the wire

• The pen attached to the weight

What is the purpose of the heavyweight in a seismograph?

• To stabilize the frame

• To rotate the paper drum

• To hold the wire in place

• To provide a steady point for the pen

What is the trace drawn by the pen on a seismograph called?

• Seismograph

• Seismogram

• Seismology

• Seismic wave
