Question

A dendritic (tree-like) drainage pattern develops in regions where the underlying material is relatively uniform so the major control on the water movement is ________.

Answer 1

Slope.

Step-by-step explanation:

As the exercise describes, a dendritic drainage patters has the form of a tree given that it all starts at the branches and, given it's slope-like inclination, descends through what would be the trunk of the tree. It's common for this patterns fo develop in regions where the underlying material is relatively uniform.
