Final answer:
Trellis drainage patterns are associated with geological folding, where main streams and tributaries flow along and across alternating rock layers, respectively, creating a network resembling a garden trellis.
Step-by-step explanation:
The stream drainage pattern that is associated with folding is typically referred to as a trellis drainage pattern. This pattern forms where tilted sedimentary layers are eroded, which is often the case with geological folding, such as with anticlines and synclines. In the trellis pattern, the main streams flow along the axis of the syncline or in the dip direction, while tributaries join the main stream at nearly right angles, reflecting the presence of the alternating resistant and less resistant rock layers that have been folded. This pattern creates a distinctive drainage network that appears as a garden trellis when viewed from above, with streams parallel to each other in some segments and then orthogonally joined by others.
