Which of the following terms describes the depositional landform formed by sediment-laden streams discharging water into standing bodies of water such as lakes or seas, resulting in an outward-projecting delta coastline?

💡 Solution & Explanation

A delta is formed when sediment-laden rivers flow into standing bodies of water, losing velocity and depositing their load in a triangular or fan-shaped pattern. Estuaries represent drowned river mouths carved by marine transgression rather than active sediment deposition. Tombolos connect islands to the mainland via sand spits. The formation of deltas depends heavily on the balance between river sediment supply and marine wave or tidal energy.
