The Moon has no atmosphere, only vacuum. There is nothing for the sound waves to travel in.
material medium is necessory to propogation of sound .on the moon their is vacuum that is no air ,therefore sound can not be propogate on the moon.thus two people on the moon can not hear echo other.
Sound is a compression/rarefaction wave in a material, such as air. There is no such thing on the moon.
Because there's no air or other form of atmosphere. Sound need some sort of medium to travel through.
Because there's no air ! They have to communicate by radio.
Sound waves travel via vibrating molecules in air or other materials (water for example). On the Moon there is no atmosphere and as such nothing for sound waves to travel in.

Sound cannot travel through medium because it does not contain any particles to pass on the sound vibrations
There is nothing to hear in space and on the moon you are too far away to hear anything from earth the scientific reason is that sound moves and bounces to our ears with gravity but because there is no gravity in space it is impossible for sounds to reach us, they simply float away
The sun burn gases and is static, where as the moon and the other planets move and are not sources of light.
They wouldn't be able to talk with there helmets off
Sure. When it's on the opposite side of the Earth, for example.
they both have one moon
