← GeographyWhich effect results from crustal dilation near fault lines?
A)Formation of grabens and rifts✓
B)Increased folding of rock layers
C)Elevated regional metamorphic grade
D)Widespread deposition sandstone layers
💡 Explanation
Graben formation happens because crustal dilation stretches the lithosphere, causing normal faulting due to extensional stress, therefore blocks subside relative to the side blocks, rather than experiencing uplift from compressional forces.
