Which mechanism causes uplift along a thrust fault during compressional stress?

💡 Explanation

When compressional stress occurs, repeated movement on a thrust fault can be accommodated until the frictional resistance is overcome; the upper plate then shears slightly upwards, causing tectonic uplift. Therefore, frictional resistance exceeding shear stress is the answer, rather than glacial melt which is a separate process, deformation causing material yielding in absence of faulting, or forces related to non-compressional stress.
