WorksheetsQuiz 3- Seismic Wave
Total questions: 10
Worksheet time: 6mins
You were provided with data showing the arrival time of the P and S waves recorded from three seismic stations. Which of these can you possibly determine?
the damage at the focus
the distance to the earthquake
the intensity of the earthquake
the location of the epicenter
From the seismogram, the distance to the epicenter can be determined by
measuring
the arrival time of surface wave
the difference in the arrival times of the P and S waves
the ratio of the amplitude of the largest P and S waves
the speed of the surface wave
An S-wave shadow zone is formed as seismic waves travel through the Earth’s body. Which of the following statements does this S-wave shadow zone indicate?
The inner core is liquid.
The inner core is solid.
The mantle is solid.
The outer core is liquid.
Why are there no P-waves or S-waves received in the P-wave shadow zone?
P-waves are absorbed and S-waves are refracted by Earth’s
outer core.
P-waves are refracted and S-waves are absorbed by Earth’s
outer core.
Both the P-waves and S-waves are refracted by Earth’s outer
core.
Both the P-waves and S-waves are absorbed by Earths outer
core.
Type of wave that can travel inside the earth.
Surface wave
Body wave
Type of wave that can travel on the surface of the earth.
Surface wave
Body wave
Wave that can travel through solids, liquids and gas.
Primary Wave
Secondary Wave
Wave that can travel through solids only.
Primary Wave
Secondary Wave
The most damaging type of surface wave.
Love Wave
Rayleigh Wave
Its motion is a combination of longitudinal compression and dilation that results in an elliptical motion of points on the surface.
