Question

Quizplus · Accepted Answer

The predominant modern-day method of determining the depth and nature of the seafloor is using sound waves through a technique called sonar (which stands for Sound Navigation And Ranging). This method involves sending out sound waves that bounce off the seafloor and return to a receiver, allowing scientists to create a detailed map of the seafloor's topography and composition. Heat, pressure, and diving are not commonly used methods for mapping the seafloor, and optics are not effective due to the darkness and depth of the ocean.
