WebThe Mid-Atlantic Ridge, which stretches for thousands of miles in the Atlantic Ocean, is the longest mountain chain on Earth. Understanding the geologic processes at the ridge, mapped here using satellite data, was crucial as scientists developed the theory of plate tectonics. (NASA Earth Observatory) by Madison Goldberg WebOn Feb. 17, 1977, WHOI's R/V Knorr, the R/V Lulu and the submersible Alvin, reached the Galapagos Spreading Center. The site was the furthest the Lulu had ever been from its homeport. During the Alvin dive, the divers were guided to the sea floor target by the trail of white clamshells strewn across the dark volcanic background. WebIt was only when scientists began sampling the deep ocean floor in the 1950s and 1960s that they realized that most of the ocean floor is composed of lava flows. In fact, more lava has erupted on the sea floor than anywhere on Earth,mostly from mid-ocean ridges -- the longest chain of active volcanoes on ourplanet. ningbo uwin stationery \u0026 gift
