Q4: SEISMIC WAVES

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?

• Inner core is liquid

• Inner core is solid

• Mantle is solid

• 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 P waves and S waves are refracted by the Earth’s outer core

• Both P waves and S waves are absorbed by the earth’s outer core.

P waves are known as transverse waves. The ground move perpendicular to the direction of the wave.

• TRUE

• FALSE

Both P waves and S waves travel in all media.

• TRUE

• FALSE

The most destructive type of wave is the Rayleigh wave.

• TRUE

• FALSE
