← GeographyWhich stress regime causes continental rift valley formation during an earthquake?
A)Tensional stress creates normal faults✓
B)Compressional stress creates regional folding
C)Shear stress generates strike-slip movement
D)Hydrostatic stress triggers induced seismicity
💡 Explanation
Continental rifting is caused by tensional regimes where the brittle crust extends because normal faults form under extension, creating faults leading to rift valleys; therefore normal faulting is a key outcome, rather than folding or strike-slip which requires compressive or shear stress.
