Which outcome occurs when tectonic subduction stalls during collision?

💡 Explanation

The primary outcome is crustal compression via isostatic response/adjustment; this leads to crustal thickening because continued convergence stress cannot be relieved. The mechanism of collision orogeny therefore forms mountains, rather than allowing subduction to continue.
