Answer 2

Answer:

Echo is a sound or series of sound caused by the reflection of sound waves from a surface back to the listener.

Sound can not be produced on earth as sound needs any particle, molecules or atoms theough which sound waves can travel from one place to another.

Since sound can not be produced on moon then we cannot hear it from the earth.
