Question

Quizplus · Accepted Answer

Remote sensing devices used to study the ocean floor include magnetometers, which detect changes in the Earth's magnetic field caused by magnetic minerals in the oceanic crust; echo sounders, which use sound waves to map the topography of the seafloor; and microwave radar instruments, which can penetrate through water and detect ocean features such as waves and currents. Therefore, all of these devices are used for ocean floor studies.
