Chris RowanThis is a nice write-up of how plate tectonics may have got going on Earth: a progressive development over a couple of billion years, from no plate boundaries, to localised and intermittent ones, to a full planetary system, makes a lot of sense. It would also explain why different lines of evidence produce such different start dates: it's a convolution of a fragmentary and intermittent process and a fragmentary and intermittent geological record. <a href="https://scicomm.xyz/tags/geology" class="mention hashtag" rel="nofollow noopener" target="_blank">#geology</a> <a href="https://scicomm.xyz/tags/PlateTectonics" class="mention hashtag" rel="nofollow noopener" target="_blank">#PlateTectonics</a><a href="https://www.nature.com/articles/d41586-024-02602-3" rel="nofollow noopener" translate="no" target="_blank">https://www.nature.com/articles/d41586-024-02602-3</a>
