Difficulty: EasyDrainage Patterns and River Basin Analysis

A drainage pattern where streams converge from surrounding elevated areas into a central inland depression or lake is best described as which of the following?

  1. Centripetal drainage patternAnswer
  2. B
    Radial drainage pattern
  3. C
    Dendritic drainage pattern
  4. D
    Trellis drainage pattern

Answer

Centripetal drainage pattern
Centripetal drainage pattern is defined by streams that flow inward from elevated margins toward a central depression, basin, or lake (such as Lake Chad).

Step-by-Step Solution

1
Analyze the stream flow direction described in the stem.
The streams flow from surrounding high areas inward toward a central low point (depression or lake).
Identifying the flow direction relative to topographic relief determines the structural drainage pattern type.
2
Match the flow direction to standard geological drainage pattern definitions.
Inward converging flow characterizes the centripetal drainage pattern.
The term 'centripetal' denotes moving or tending toward a center point.
