Matching Rivers to Delta Types

The question requires matching specific rivers (List – I) with the type of delta they form (List – II). The correct matching sequence is determined by the geographical characteristics of each river's delta.

River Delta Type Analysis

Here is a breakdown of each river and its corresponding delta type:

• I. Nile River: Forms an Arcuate delta. This classic delta shape occurs when sediment deposition is influenced by wave action along a relatively straight coastline. (I → B)
• II. Mississippi River: Forms a distinctive Bird foot delta. This occurs when a river carries a large sediment load into a standing body of water (like a sea) where wave action is minimal, causing the delta to extend outwards like bird's toes. (II → C)
• III. Ganga River: Forms an Estuarine delta. This type of delta forms in the mouth of a river where tidal currents are strong enough to prevent significant outward delta building, leading to a funnel shape influenced by estuaries. (III → A)
• IV. Tiber River: Forms a Cuspate delta. This is a triangular delta formed when sediment is deposited along a straight coastline, and wave action distributes the sediment symmetrically, creating a pointed or cusp-like shape. (IV → D)

Correct Code Selection

Based on the individual matchings (I → B, II → C, III → A, IV → D), the correct code sequence representing the match for I, II, III, IV is B C A D.
