Final answer:
The statement is False. Surface waves, which are not the slowest waves, cause the most damage due to their rolling motion.
Step-by-step explanation:
The statement 'Travel upon the ground, slowest waves, but cause the most damage due to their rolling motion' is False.
Waves that travel upon the ground are called surface waves. Although they do cause a significant amount of damage due to their rolling motion, they are actually not the slowest waves. The slowest waves are called longitudinal waves, which travel through a medium by causing the particles to vibrate parallel to the direction of wave propagation.
Examples of surface waves include seismic waves during an earthquake.
