Final answer:

The underlying rock of the dendritic drainage pattern is typically composed of homogeneous, non-resistant rock that allows water to flow easily through it.

Step-by-step explanation:

This type of rock allows water to flow uniformly and evenly, creating a branching network of streams and rivers.

Here are some key points about the underlying rock of a dendritic drainage pattern:

  • 1. Homogeneous composition: The rock is made up of layers that have similar properties and characteristics throughout. This uniformity allows water to flow smoothly and consistently across the landscape.

  • 2. Flat-lying layers: The sedimentary rock layers are generally deposited in horizontal or nearly horizontal orientations. This flat-lying nature provides a relatively even surface for water to flow over, facilitating the formation of a dendritic pattern.

  • 3. High permeability: The rock has a high permeability, meaning it allows water to easily pass through it. This enables efficient water flow and contributes to the formation of a well-developed dendritic drainage system.

  • 4. Lack of structural control: The dendritic drainage pattern is not influenced by the structural features of the underlying rock, such as faults or folds. Instead, it primarily reflects the topography and the uniformity of the rock layers.
