← GeographyWhich outcome results along coastlines undergoing longshore drift?
A)Sand deposition at river mouths✓
B)Uniform seabed composition offshore
C)Increased coral reef biodiversity
D)Decreased coastal sediment supply
💡 Explanation
Sand deposition occurs at river mouths undergoing longshore drift because this is where sediment-laden currents slow down, resulting in Sedimentation. Flow deceleration leads to sediment accumulation, therefore promoting deposition, rather than dispersing sediment uniformly.
