What is the main difference between an estuary and a delta at a river mouth?
Answer and explanation
Correct answer: Tidal action removes sediment in an estuary while deposition dominates in a delta
An estuary is a funnel-shaped river mouth where strong tides and currents can keep sediment moving or remove it, leaving a relatively open channel. A delta develops where river flow enters quieter water and loses energy, allowing sediment to accumulate and build distributaries and depositional lobes. The distinction is therefore mainly the balance between tidal removal and river deposition. Option B is correct; the other choices use incorrect agents or locations.
