← GeographyWhich process controls uplift when two continental plates collide at reverse fault zones?
A)Isostatic rebound from glacial melt
B)Elastic deformation of upper crust
C)Brittle fracturing and wedge accretion✓
D)Ductile flow in the lower mantle
💡 Explanation
When continental plates collide, compression at reverse faults causes brittle fracturing which accretes material on the overriding plate, leading to upward displacement. Therefore brittle fracturing results, rather than other uplift related to glacial unloading, elastic strain which mostly generates seismicity, or mantle dynamics that are far deeper.
