Which outcome results from thermal expansion in permafrost?

💡 Explanation

Development of patterned ground features results from freeze-thaw cycles; they exploit thermal volume changes because differential expansion forms ice lenses thus sorting soil; therefore, patterned ground emerges rather than methane instability involving clathrates or carbon cycle feedbacks.
