What is the difference between Compressional waves and Shear Waves of Earthquakes? |
(i) Compressional waves push and pull the rocks |
(ii) Shear waves makes rocks bend or slide from side to side |
(iii) Shear waves can travel through solids, liquids, or gases, while Compressional waves can pass only through solids. Which of the statements given above is/ are correct? |
A) i and ii only
B) i and iii only
C) ii only
D) i, ii and iii
Correct Answer: A
Solution :
[a] Body Waves: Are the fastest seismic waves, move through the earth's lower surface; these waves travel along the surface of the earth. Body waves tend to cause the most earthquake damage. There are two kinds of body waves: (1) Compressional waves and (2) Shear waves. As the waves pass through the earth, they cause particles of the rock to move in different ways. Compressional waves push and pull the rock. They cause building and other structures to contract and expand. Shear waves make rocks bend or slid from side to side and building shake. Compressional waves can travel through solids, liquids, and gases, but shear waves can pass only through solids.You need to login to perform this action.
