Describe the major drainage patterns. What will be an ideal response?
In dendritic drainage, a network of channels resembles tree branching. The pattern develops on gently
sloping surfaces underlain by material that erodes roughly equally. Tributaries join larger channels at
various angles. In rectangular drainage, tributaries join larger channels at right angles; this pattern is
controlled by geologic structures, such as joints. Trellis drainage is a network of nearly parallel
streams with tributaries joining them at right angles because the streams follow easily eroded rocks
and are separated by resistant rocks. In radial drainage, streams flow outward from a high point like a
volcano. Deranged drainage patterns are irregular, with streams flowing into and out of swamps and
lakes.
