Which mechanism forms lagoon ecosystems behind coastal barriers?

💡 Explanation

Sediment deposition leads to coastal barrier and lagoon formation by longshore drift, because transported material accumulates offshore, parallel to the coast. This process is termed littoral accretion; therefore, lagoon ecosystems are formed behind the barriers, rather than by other geological mechanisms.

• Which outcome occurs when vegetation removal alters longshore currents?
• Which outcome results when extensive soil disturbance by agriculture precedes intensified desert deflation?
• Which phenomenon occurs when deflation removes fine sediment?
• Which ecological pattern consistently arises adjacent arid coastal regions as persistent offshore winds drive coastal upwelling?
• Which outcome occurs when an eruption column collapses?
• Into which feature does a confined aquifer discharge?
