← GeographyNear coral reef islands, which process maintains channel depths?
A)Tidal scouring creates deeper sections✓
B)Halocline stratification prevents mixing
C)Eustatic sea level decline exposes
D)Isostatic rebound uplifts the sediments
💡 Explanation
Tidal scouring maintains channel depths because it erodes sediments due to increased flow during tides; therefore, channels deepen rather than becoming shallow. Halocline stratification has related density driven flow behavior with varying effects, rather than targeted channel maintenance
