P-Waves and S-Waves

The seismometer sends signals to a seismograph, which records the earthquake as a series of lines on a graph called a seismogram. Objectives: The student will: correctly label illustrations of P-Waves and S-Waves; • correctly label the starting points of P-Waves and S-Waves on a seismograph; and • use a ...
