Define drainage pattern.

A drainage pattern is the arrangement of natural streams and rivers in a particular area, forming a network that drains water from the land into larger bodies of water such as lakes, oceans, or other rivers. Drainage patterns are influenced by factors such as topography, geology, and climate, and can take on various forms such as dendritic, radial, rectangular, and trellis patterns.

Drainage pattern refers to the organized and hierarchical network of waterways, including rivers, streams, and tributaries, that form a recognizable pattern on the Earth's surface. This network is responsible for the collection, transportation, and discharge of water from the land to larger bodies of water, such as oceans or lakes. Drainage patterns vary in appearance and are influenced by various factors, including the underlying geology, topography, climate, and vegetation of a region.
