← GeographyWhich beach change results when groynes interrupt coastal sediment transport?
A)Increased erosion downdrift of groynes✓
B)Formation of extensive offshore bars
C)Accelerated chemical weathering of cliffs
D)Reduced storm surge flooding inland
💡 Explanation
Reduced sediment supply downdrift causes increased erosion because groynes trap sediment in their updrift side, disrupting the natural longshore drift process; therefore, erosion increases downdrift, rather than offshore bar formation occurring from sediment deposition.
