Drainage patterns MCQ — 2 Practice Questions with Answers

Explanation

A trellis drainage pattern develops where the main tributaries run nearly parallel and smaller tributaries join them at right angles, often in folded or alternating hard and soft rock terrain. A centripetal pattern has streams flowing inward towards a basin or depression. A radial pattern has streams flowing outward from a central highland, such as a dome or volcanic cone. A dendritic pattern resembles tree branches and forms where rock resistance is fairly uniform. The description given matches the trellis pattern.

Explanation

A radial drainage pattern forms when streams flow outward in different directions from a central highland, dome, or hill. The Amarkantak range is a classic Indian example because rivers originate there and move away in multiple directions. A trellis pattern develops in folded terrain with parallel valleys. A centripetal pattern drains inward towards a basin or depression. A dendritic pattern looks tree-like and usually develops on uniform rock. The description in the question fits radial drainage.
