Question 1278
Which drainage pattern is commonly found in Ganga plains and Assam Valley, characterized by wide plains, gentle slopes, heavy rains and large number of tributaries?
Answer
Dendritic drainage pattern
Why?
The correct answer is option 2 . Key Points The dendritic drainage pattern resembles the branches of a tree, with numerous tributaries joining larger rivers at various angles. Hence, option 2 is correct. It commonly develops in regions with uniform lithology (similar rock types), wide plains, and gentle slopes, like the Ganga plains and the Assam Valley. The pattern is typical where the landscape allows rivers to follow the natural slope without structural control. Drainage Pattern Typical Regions Characteristics Dendritic Ganga Plains, Assam Valley Tree-like branching, many tributaries, gentle slope Antecedent Mountainous regions Rivers maintain original course despite uplift Radial Volcanic cones, hills Radiate outward like spokes of a wheel Rectangular Faulted or jointed terrains Tributaries meet at right angles
