What type of drainage network develops in regions where the bedrock has uniform resistance to erosion?

Dendritic drainage networks develop in areas where the underlying bedrock has uniform resistance to erosion. This kind of network is characterized by a branching pattern that resembles the limbs of a tree, with tributaries flowing into larger river systems. In such regions, the river and its tributaries primarily follow the slope of the terrain, creating a pattern that is influenced by the overall topography rather than variations in rock hardness or structure.

In contrast, when a drainage network exhibits features such as right-angle bends or parallel streams, it indicates the influence of structural factors or varying resistance in the bedrock, which may correspond to the other types of drainage networks. For example, rectangular drainage occurs in regions with a well-defined set of joints or faults, trellis drainage is typical in areas with alternating hard and soft rock layers that influence stream patterns, and radial drainage often forms around a central peak or volcano where streams flow outward in all directions. Understanding the formation of these drainage patterns helps in interpreting the geological and geomorphological history of a region.
