How do scientists map features of the ocean floor using sonar?

Scientists use sonar to map the ocean floor by sending sound waves from a ship to the ocean floor. These sound waves bounce back and are picked up by a receiver on the ship, providing information about the depth and texture of the ocean floor. By analyzing the time it takes for the sound waves to return, scientists can create detailed maps of the underwater terrain.
