Match List-I with List—II and select the correct answer using the code given below the Lists : List-I (Delta) A. Arcuate delta B. Bird’s-foot delta C. Cuspate delta D. Estuarine delta List-II ( Example) 1. Nile Delta 2. Mississippi Delta 3. Tiber Delta 4. Seine Delta Code :

The classification of river deltas is based on their shape and the dominant forces at the river mouth. An Arcuate delta is fan-shaped or bow-shaped, with the Nile River being the classic example [4]. A Bird’s-foot delta, characterized by long, finger-like distributaries, is exemplified by the Mississippi River [5]. Cuspate deltas are pointed, tooth-like projections formed by strong wave action, with the Tiber River in Italy serving as the primary example [2]. Finally, an Estuarine delta forms when a river mouth is submerged, creating a funnel-like shape where sediment fills the estuary; the Seine River in France is a notable example of this type. Matching these pairs (A-1, B-2, C-3, D-4) leads to the correct sequence 1, 2, 3, 4.
