reaches the earth through
A Sound Waves
B. Longitudinal Waves
C. Electromagnetic Waves
D. None of these
3. Solids, liquids, and gases differ in the way the molecules that make them up are
arrange. When
sound propagates, the energy it carries is transferred from
molecule to molecule.
Molecules of solids are closest to one another compared to liquids and gases. The energy carried
by sound can easily transfer thus sound travels in solids
