Tectonic uplift affects long-term climate stability on abiotic Earth-like planets, creating fluctuations in temperature.
The model indicates that weatherable minerals must be consistently resupplied to prevent extreme climate changes and maintain habitability.
Consideration of outgassing variability reveals critical impacts on climate stability and potential for catastrophic warming events.
Multiple resupply mechanisms, including glacial erosion and wind-driven dust, are essential for sustaining habitable conditions on these exoplanets.

Model investigates how tectonic collisions and weathering affect long-term habitability, suggesting additional mechanisms are needed.

Coy et al. (2025) studied this question.
