multiple choice question
how do surface waves affect earth materials?
o they cause particles to move back and forth in the same direction that the waves are traveling.
o they cause particles to move in a up - and - down rolling motion.
o they cause the particles to move perpendicular to the direction that the waves are travelling.

Explanation:

Surface waves cause particles to move in a up - and - down rolling motion. This is a characteristic behavior of surface waves in the context of wave - particle interaction.

Answer:

They cause particles to move in a up - and - down rolling motion.
