Story summary

A new tectonic regime called the episodic-squishy lid could reshape our understanding of planetary evolution.
The regime explains why Earth became geologically active while Venus remained stagnant, through lithospheric cycles driven by magmatism.
Advanced simulations show the lithosphere can cycle between quiet periods and bursts of tectonic activity, influenced by magmatism.
The framework suggests Earth's lithosphere transitioned through a squishy-lid phase before full plate tectonics, affecting habitability assessments and exploration planning.
