Question

Hiw do the trellis pattern ormed by the rivers

Answer 1

The geometry of a trellis drainage system is similar to that of a common garden trellisused to grow vines. As the river flows along a strike valley, smaller tributaries feed into it from the steep slopes on the sides of mountains. These tributaries enter the main river at approximately 90 degree angle, causing a trellis-like appearance of the drainage system. Trellis drainage is characteristic of folded mountains, such as the Appalachian Mountains in North America and in the north part of Trinidad
