The sediment deposited where a river flows into an ocean or a lake creates a delta. This occurs when the movement of a river decreases as it enters calmer water, causing the sediment to fall and build up over time. Deltas are known for their high wildlife diversity and fertile soils. ;
The correct answer is:
Delta , when sediments are deposited where a river flows into an ocean it forms a delta. ;
Sediment deposited where a river meets an ocean or lake forms a delta, a landform created by sediment accumulation as river flow slows. Deltas can appear in various shapes and are vital for biodiversity and agriculture. They are commonly found at the mouths of major rivers.
