Why Venus Failed Plate Tectonics

Earth and Venus are nearly twins in size and composition. Yet one became a planet of moving plates and the other did not. In this video, we explore why Venus failed to develop plate tectonics, not as a mystery of chance, but as a consequence of physics, heat, and timing. Why didn’t Venus form long-lived subduction zones? Why did slab pull never switch on? And what role did water, cooling, and lithospheric strength play in sending Earth and Venus down radically different evolutionary paths? This is plate tectonics explained from first principles, by comparing what Earth gained and what Venus lacked. 🌍 What this video explores • Why slab pull is essential for sustained plate tectonics • How Venus stayed too hot to form dense, sinking slabs • The role of water in weakening rocks and enabling subduction • Stagnant-lid vs plate-tectonic planets • Why Venus releases heat catastrophically, not continuously
