Sonar waves are sound waves which travel in water and bounce back from the ocean floor

Explanation:

geoscientists use the sonar waves by placing sonar sources on a tube which is floating on water. Then they send sound waves inside the water. The time it takes for the waves to bounce back and come back to the detector is recorded and a map is produced by it
