Is it true that maps made from sonar and magnetometer data led to the discovery of ocean ridges and deeps sea trenches?

Yes, maps created from sonar and magnetometer data played a crucial role in the discovery of ocean ridges and deep-sea trenches. Sonar technology allowed scientists to map the seafloor's topography, revealing features like mid-ocean ridges and deep trenches. Meanwhile, magnetometer data helped identify patterns of magnetic anomalies, providing insights into seafloor spreading and tectonic activity. Together, these tools significantly advanced our understanding of oceanic geology.
