Explosions are not heard on the Moon away from the surface

Explosions are not heard on the Moon away from the surface; option [A] Due to the absence of atmosphere. Sound waves are mechanical waves that require a medium, such as air or water, to propagate. On the Moon, which lacks a substantial atmosphere, there are no air molecules to transmit sound waves from explosions to an observer’s ears. Therefore, even though explosions create vibrations and shockwaves, these cannot be perceived audibly in the vacuum of space.

While the Moon’s lower gravity affects how materials behave and interact during explosions, it does not directly impact the propagation of sound waves. The absence of an atmosphere is the primary reason why sounds, including explosions, are not heard on the Moon’s surface or in its surrounding vacuum. Thus, the correct answer to why explosions are not heard on the Moon away from the surface is [A] Due to the absence of atmosphere.
