Webcrust formed near mid-ocean ridges are older than those farther from the ocean ridge 10. as a new sea floor is formed at the mid ocean ridge, the old sea floor farthest from the ridge is destroyed. which of the stated processes describes how the oceanic crust plunges into the earth and destroyed at the mantle Web10 de nov. de 2024 · It formed and evolves as a result of spreading in Earth’s lithosphere—the crust and upper mantle—at the divergent boundaries between tectonic plates. The vast majority of volcanic activity on the planet occurs along the mid-ocean ridge, and it is the place where the crust of the Earth is born. WebVolcanoes are created over approximately 10,000-500,000 years by thousands of eruptions -- each lava flow covering the one before it. In the case of oceanic island volcanoes, lava erupts first from fissures, or cracks, on the deep ocean floor. The flows continue to build up and finally an island emerges from the sea. how do i drag and drop files

WebA mid-ocean ridge ( MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin.
