Which outcome occurs when vegetation anchoring coastal dunes dies?

A)Increased dune migration inland.
B)Decreased sediment supply increases.
C)Formation of new beach terraces.
D)Reduced wave energy deposition.

💡 Explanation

Increased dune migration results from reduced root cohesion, because the anchoring vegetation's *root binding* mechanism fails, therefore mobile sand is transported further inland; rather than beach terraces forming, which require different forces involving longshore transport.
