What is the role of vegetation in salt-marsh coastal deposition?
Answer and explanation
Correct answer: Vegetation traps sediment and helps raise the surface
Salt-marsh plants create stems and roots that obstruct shallow tidal flow. This lowers water velocity and allows suspended silt and clay to settle. The vegetation also binds the deposited material, helping the marsh surface build vertically and expand laterally when sediment supply continues. Hence option A is correct. The other choices assign vegetation processes to sea-cliff erosion, glacial melting or cave formation, which are not applicable.
