Select the word frthe type of seismic waves that arrive at the surface first and move by compressing and expanding the ground like an accordion are called a. s waves. b. p waves. c. surface waves. d. mercalli waves. select the best answer from the choices provided a b c d

Option (B)

Explanation:

Seismic P waves are the primary waves that are generated during an earthquake. This wave propagation can be marked by the alternating compression and extension. The speed of this wave is 4-8 km/sec on average. It can travel at a faster rate, in comparison to the  S waves. So they reach the surface fast. They can travel in both solid as well as liquid. But these waves are less dangerous than the S waves as surface waves propagate through the surface causing a lot of damage.

Thus, the correct answer is option (B).

any one of the statements could be an accurate comparison. but the statement that would define the correct choice and seal the deal is not even on the list:

"the visibilities of vector-x and vector-y in the drawing provided with the question are identical and nonexistent."

are there options? cause you ain’t. real specific
