Question

which type of seismic wave moves the fastest?
a. type 1 surface waves
b. type 2 surface waves
c. s - waves
d. p - waves

Explanation:

Seismic waves include P - waves (primary waves), S - waves (secondary waves), and surface waves. P - waves are compressional waves and can travel through solids, liquids, and gases. They are the fastest seismic waves. S - waves are shear waves and can only travel through solids, slower than P - waves. Surface waves are slower than both P - and S - waves and are the most destructive.

Answer:

D. P-waves
