Quizplus · Accepted Answer

Remote sensing and mapping of mineral deposits by satellites may have provided valuable information about the locations of mineral deposits, but it did not contribute significant geologic knowledge about the rocks, structures, and mineral deposits of the mid-ocean ridges themselves. The other methods mentioned all provided direct observations and measurements of the ocean floor and its features.
