Dendritic drainage pattern resembles the branches of a tree. It is the most common and widely found pattern in nature. In this pattern, the river channels and tributaries resemble the branches of a tree, with the main river channel acting as the trunk and the smaller tributaries acting as the branches that merge into the main channel.

Explanation:
The dendritic drainage pattern develops in regions with a homogeneous rock structure and a relatively flat and uniform slope. It is formed when a river flows over a uniform and resistant bedrock or a layer of unconsolidated sediments. The river channels follow the paths of least resistance and erode the surrounding terrain in a dendritic pattern.

The formation of a dendritic pattern can be explained as follows:

1. Homogeneous rock structure: The underlying rock or soil in the area is uniform and does not have any major variations in its resistance to erosion. This allows the river to flow freely and not be diverted by any harder or softer rock formations.

2. Uniform slope: The area has a relatively flat and uniform slope, which means that the river does not encounter any significant changes in gradient. This smooth gradient allows the river to flow evenly and maintain a consistent direction.

3. Path of least resistance: The river follows the path of least resistance as it flows downhill. It erodes the surrounding terrain in a way that creates a network of branching channels. The erosion is concentrated along the weaker points in the landscape, such as joints or fractures in the rock.

4. Branching tributaries: As the river flows downstream, it is joined by smaller streams and tributaries. These tributaries form at right angles to the main channel and join it, creating a dendritic pattern resembling the branches of a tree.

The dendritic drainage pattern is efficient in draining water from an area because it allows for a large volume of water to be discharged into the main river channel. It is commonly found in regions with well-developed drainage systems, such as river valleys and floodplains.
