What is the defining characteristic of a radial drainage pattern?

A radial drainage pattern is characterized by streams and rivers that flow outward from a central point, typically a peak or a mountain. This geological formation often occurs in areas where volcanic activity or a mountain range provides a high point, allowing the water to radiate in multiple directions down the slopes.

In this pattern, the rivers are arranged like the spokes of a wheel, diverging from the central elevation. This is distinct from other drainage patterns; for instance, a pattern that flows parallel to the coastline involves different hydrological processes and landforms, while circular flow around a low area applies to different topographic conditions, such as basins. Additionally, flows through a valley between two hills indicate a linear drainage pattern rather than a radial one, which focuses on the central point's influence.
