What is the trellis pattern characterized by?

• A. A rectangular pattern with tributary streams appearing parallel
• B. A chaotic pattern with irregular tributaries
• C. A circular drainage pattern around a central point
• D. A linear pattern aligning strictly with the main river

Answer: (A)

The trellis pattern is characterized by a rectangular arrangement of streams, where tributary streams run parallel to each other and join a main river at right angles. This pattern typically forms in areas with alternating bands of resistant and softer rock, where the streams erode differentially, leading to a distinct geometric arrangement. The parallel tributaries reflect the geological structure of the area, which guides their flow and alignment. In trellis systems, the main river flows across the contours of the land, while tributaries manage to develop more vertically, creating the characteristic trellis-like grid. This understanding of the trellis pattern highlights its distinctive arrangement and the geological conditions that contribute to its formation, differentiating it from other patterns seen in drainage systems.
