Q1When the primary tributaries of a river flow parallel to each other and secondary tributaries join them at right angles, the pattern is known as _________.
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.
Q2Rivers originating from the Amarkantak range and flowing in all directions are an example of which of the following drainage patterns?
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.
