Compressional waves , also called ​ (a)   cause the material through which they move through which they pass to vibrate in the ​ (b)   as the wave traveling.

Shear waves, also called​ (c)   , cause the material through which they pass to vibrate at ​ (d)   .

• Primary or P-waves
• same direction
• Secondary or S-waves
• right angles

L-waves (​ (a)   ) or surface waves are ​ (b)   waves that ripple the surface of the Earth causing the ​ (c)   associated with earthquakes.

• long period waves
• Rayleigh and Love
• damage

What is the difference between the Love wave and Rayleigh wave?

• Rayleigh wave goes in a circular motion

  The love wave goes side to side

• Love wave goes in a circular motion

  The Rayleigh wave goes side to side

• Love wave goes moves particles in the same direction it moves

• Rayleigh move particles in a 90 degree angle
