Why can waves with a lower frequency follow the earth's surface?

1.	Why can waves with a lower frequency follow the earth's surface?
Answer» ANSWER: The molecules in the medium, as they are forced to vibrate back and forth, generate heat. CONSEQUENTLY, a sound WAVE can only propagate through a LIMITED distance. In GENERAL, low frequency waves travel furtherthan high frequency waves because there is less energy transferred to the medium.
