Is the st Lawrence and fraser river dendritic or trellis?

The St. Lawrence River exhibits a dendritic river pattern, characterized by its branching and tree-like structure. This pattern occurs due to the varying resistance of the underlying geology, allowing the river to meander and create a network of tributaries. In contrast, the Fraser River in British Columbia primarily shows a dendritic pattern as well, though it can exhibit some characteristics of a trellis system in certain areas where tributaries enter at right angles due to geological folding. Overall, both rivers are primarily dendritic in nature.
