Worksheet • 5 Questions • 1 Video

Q1:

Which of the following statements about S-Waves is not correct?

  • AS-waves are longitudinal.
  • BS-waves travel through solids.
  • CS-waves cannot travel through Earth’s core.
  • DS-waves are slower than P-waves.

Q2:

Which of the following statements about P-waves is not correct?

  • AP-waves are slower than S-waves.
  • BP-waves are longitudinal.
  • CP-waves travel through liquids.
  • DP-waves travel through solids.

Q3:

The position of an earthquake’s epicenter is shown in the diagram. P-waves and S-waves are emitted from the epicenter. Three seismic sensor stations A, B, and C are shown.

Which station will detect only S-waves?

  • AStation C
  • BStation A
  • CNone
  • DStation B

Which station will detect only P-waves?

  • ANone
  • BStation A
  • CStation C
  • DStation B

Which station will detect S-waves and P-waves?

  • AStation A
  • BStation B
  • CNone
  • DStation C

Which station will detect neither P-waves nor S-waves?

  • AStation B
  • BStation A
  • CNone
  • DStation C

Q4:

The diagram shows the paths of P-waves and S-waves traveling through Earth from an earthquake epicenter. At each of the points 𝐴 , 𝐵 , 𝐶 , and 𝐷 , a wave is either transmitted, absorbed, reflected, or refracted.

At 𝐴 , is the wave transmitted, absorbed, reflected, or refracted?

  • ARefracted
  • BTransmitted
  • CReflected
  • DAbsorbed

At 𝐵 , is the wave transmitted, absorbed, reflected, or refracted?

  • ARefracted
  • BTransmitted
  • CReflected
  • DAbsorbed

At 𝐶 , is the wave transmitted, absorbed, reflected, or refracted?

  • AAbsorbed
  • BTransmitted
  • CRefracted
  • DReflected

At 𝐷 , is the wave transmitted, absorbed, reflected, or refracted?

  • AReflected
  • BTransmitted
  • CRefracted
  • DAbsorbed

Q5:

The Earth has two main layers below its crust; the core and the mantle. The core has an outer and inner region, as shown in the diagram. The temperature of and the pressure on the material in the mantle and the core increase with depth below the crust.

Does the material of the mantle exist in a solid, liquid, or gaseous state?

  • ALiquid
  • BSolid
  • CGaseous

Does the material of the outer core exist in a solid, liquid, or gaseous state?

  • ASolid
  • BLiquid
  • CGaseous

Does the material of the inner core exist in a solid, liquid, or gaseous state?

  • ALiquid
  • BSolid
  • CGaseous
