← GeographyWhich mechanism influences stream course alignment in areas bisected by a transform fault?
A)Lateral displacement from block motion✓
B)Downcutting owing to increased gradient
C)Aggradation due to sediment obstruction
D)Capture resulting from increased discharge
💡 Explanation
When transform faults move, lateral displacement of land occurs because the fault allows strike-slip motion along its plane, causing blocks to shift horizontally affecting nearby terrain. Therefore lateral displacement leads to stream course alignment rather than downcutting, aggradation, or capture, which depend differently on gradient, sediment, or discharge.
