← Earth & Natural SystemsA coastal engineer proposes planting mangrove forests to protect a shoreline. Which outcome occurs when mangrove root systems are fully established?
A)Increased offshore wave energy amplification
B)Elevated water table, promoting soil salinization
C)Decreased organic material sediment decomposition rate
D)Enhanced sediment trapping, promoting land accretion✓
💡 Explanation
Mangrove root systems trap sediment because their dense structure slows water flow, allowing suspended particles to settle, therefore promoting land accretion rather than wave amplification or hindering decomposition; this is not related to the water table.
