What Sonar functions by bouncing sound waves off the ocean bottom and recording the length of the time required for their return true or false?
True, sonar functions by emitting sound waves that bounce off objects in the water (such as the ocean bottom) and measuring the time it takes for the echoes to return. This information is then used to create a map of the underwater environment.
