Which of the following stream channel types is likely to develop on gently sloping surfaces composed of rocks or sediments with approximately the same resistance to erosion? (Also assume that there are no structural controls on the pattern's development.)
A) radial
B) annular
C) deranged
D) dendritic

Dendritic channel patterns are the most common and form where the underlying rocks or sediments are uniform in resistance to erosion. Such conditions result in a well-developed and interconnected drainage network resembling the branching pattern of a tree. Radial patterns occur on isolated mountaintops, annular patterns form around a central high area, and deranged patterns result from tectonic activity or glaciation. Therefore, given the conditions specified in the question, the most likely channel pattern to develop is dendritic.
