← GeographyWhich sedimentary outcome emerges during longshore drift when wave refraction diminishes?
A)Spit formation at bay mouths✓
B)Increased offshore sandbar migration
C)Accelerated erosion of headlands
D)Amplified tidal channel scouring
💡 Explanation
Spit formation results because reduced wave energy diminishes sediment transport; therefore deposition dominates near a bay mouth which causes spit growth. This accretion process occurs there, rather than increased erosion, offshore migration, or channel development because these need stronger wave energy.
