Question

Match the definitions to the words

1.    Seismic shadow zone
2.    Triangulation  
3.    Rayleigh waves 
4.    Love waves

A.  A process used to determine the epicenter of an earthquake
B.  A surface wave that causes horizontal motion
C.   Areas on the earth’s surface where waves traveling through the earth don’t arrive due to refraction
D.  A surface wave that causes vertical motion
​

Answer 1

The correct matching is 1: C, 2: A, 3: D, 4: B.

Step-by-step explanation:

• Seismic shadow zone is an area on the surface of the earth where the waves cannot travel due to the presence of liquid.
• Triangulation is the process which is used by the scientists to determine the epicenter of the earthquake.
• Rayleigh waves cause motion in the deep earth both in horizontal and vertical motions.
• Love wavers are the waves that cause motion in the deep earth in horizontal motion only.
