Ramin Skibba, Discover Magazine, 1 Mar. 2023 Those stresses then weaken the outer crust, aiding or generating plate tectonics similar to those seen on Earth. 2023 One thing that came up when Newitz talked to planetary scientists and geologists was plate tectonics, the movement of large portions of the Earth’s surface that builds mountains but also causes earthquakes and tsunamis. 2023 By using the lasers to squeeze samples of rocks and metals to those deep planetary pressures, researchers can see how the samples behave, discovering their resistance to flow (important for plate tectonics) or their ability to conduct electricity (important for magnetic-field generation). 2023 For years, scientists have been revising the notion that our nearest planetary neighbor is geologically dead, as different studies converge on the conclusion that some of its volcanoes are active even without plate tectonics, which fuels most of them here on Earth. Marissa Grunes, Discover Magazine, 6 Apr. Alex Fox, Smithsonian Magazine, 23 June 2021 If Mars had plate tectonics, those also stopped long ago. 2023 This type of activity doesn’t constitute true plate tectonics, explains Robin George Andrews for the New York Times, because not all of Venus’ surface is covered by jostling plates of crust and those plates don’t appear to slide over or under one another as Earth’s do. ![]() Conor Feehly, Discover Magazine, 15 Apr. ![]() Recent Examples on the Web Additionally, while it’s currently understood that Venus does not have Earth-like plate tectonics, data provided by Magellan has shown tectonic structure like folds, faults, rift zones and mountains across the planet.
