WebScientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and identify objects in the water column and on the seafloor such as shipwrecks, and map the seafloor itself. Sonar is used for oceanography because sound waves travel farther in the water than radar and light waves can. WebScientists can only guess when the first plates formed and how they behaved further back than that. The force that moves the plates is thought to be convection currents in the mantle under the Earth’s crust. The mantle is solid in the short term, but flows very slowly over geologic timescales.
