Before Pangea, before dinosaurs—even before oxygen filled the air—continents were on the move. In this Howtown episode, we travel billions of years into the past to explore a groundbreaking new plate tectonic model. Discover how scientists trace ancient continents using zircon crystals, magnetic minerals, glacial scars, and more. From massive dike swarms to lost supercontinents like Rodinia and Nuna, we unravel the clues that reveal Earth's epic tectonic story.</p><p>🔬 Featuring: Paleomagnetism, zircon dating, cratons, and the surprising history of plate tectonics<br>🛰️ NASA satellites, moon rocks, and ancient Canadian crust<br>👥 With special guest Joe Hanson.</p><p>Watch Joe's companion video on zircon dating here → <a href="https://www.youtube.com/watch?v=c4GRLFuTyQY" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">youtube.com/watch?v=c4GRLFuTyQ</span><span class="invisible">Y</span></a> (🛡️ <a href="https://id.420129.xyz/watch?v=c4GRLFuTyQY" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">id.420129.xyz/watch?v=c4GRLFuT</span><span class="invisible">yQY</span></a>)</p><p>Key Source: Earth’s tectonic and plate boundary evolution over 1.8 billion years, Xianzhi Cao et al (2024) <a href="https://www.sciencedirect.com/science/article/pii/S1674987124001464" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">sciencedirect.com/science/arti</span><span class="invisible">cle/pii/S1674987124001464</span></a></p><p>Full Source List: <a href="https://docs.google.com/document/d/14lCuGV0pR0kMJjlOAbgOTf-SH3WTpKsu5yV9ygTVLOQ/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">docs.google.com/document/d/14l</span><span class="invisible">CuGV0pR0kMJjlOAbgOTf-SH3WTpKsu5yV9ygTVLOQ/</span></a>"</p><p><a href="https://todon.eu/tags/geology" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>geology</span></a> <a href="https://todon.eu/tags/geography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>geography</span></a> <a href="https://todon.eu/tags/PlateTectonics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PlateTectonics</span></a> <a href="https://todon.eu/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>science</span></a></p>
