1. It represents the most common pattern of streams and their tributaries: The dendritic pattern is indeed the most widespread and common drainage pattern.
2. It occurs in areas of uniform rock type and regular slope: This pattern develops where the underlying rock structure is homogeneous and offers no particular resistance or guidance to the flow of water, allowing streams to erode and branch freely.
3. A map, or aerial photograph, shows a pattern like the veins on a leaf—smaller streams join the main stream at an acute angle: The branching, tree-like appearance where tributaries join the main channel at angles less than 90 degrees is characteristic of a dendritic pattern, resembling the venation of a leaf.
