← GeographyWhich mechanical result primarily occurs when a fault rupture propagates to the earth's surface along a strike-slip fault?
A)Lateral displacement of surface features✓
B)Formation of deep, narrow canyons
C)Widespread pyroclastic flows
D)Uniform uplift of overlying strata
💡 Explanation
When fault rupture propagates to the surface on a strike-slip fault, lateral displacement occurs because the blocks on either side slide horizontally relative to each other, leading to distinct offsets. Therefore, lateral displacement results, rather than canyon formation, pyroclastic flows, or uniform uplift which involve respectively, erosion processes, volcanic eruptions, and vertical fault motion.
