1c. in your own words, explain how seismic waves move. write your answer here...

Answer:

Seismic waves can move in two main ways. Body - waves (P - waves and S - waves) travel through the Earth's interior. P - waves are compressional waves that move by pushing and pulling particles in the direction of wave motion. S - waves are shear waves that move particles perpendicular to the wave direction. Surface waves move along the Earth's surface and are slower but can cause more damage. Love waves move the ground from side - to - side and Rayleigh waves make the ground move in an elliptical motion.

Brief Explanations:

Based on the knowledge of seismic wave types (body and surface waves) and their motion characteristics in Earth science.
