How are mid-ocean ridges mapped?


submarines

taking pictures

scuba divers

sonar

Answer 1

Mid-ocean ridges are primarily mapped using **sonar**. Sonar (Sound Navigation and Ranging) works by emitting sound waves from a ship and measuring the time it takes for the echoes to return after bouncing off the ocean floor. This method allows researchers to create detailed maps of the seafloor, including the topography of mid-ocean ridges. Other methods, like taking pictures from submersibles or remotely operated vehicles, can supplement this data, but sonar is the most common and effective method for mapping large areas of the ocean floor.
