describe the main types of drainage pattetns
Answers
Dendritic
A dendritic drainage pattern is the most common form and looks like the branching pattern of tree roots. It develops in regions underlain by homogeneous material.
Deranged
Drainage patterns are found in areas recently disturbed by events like glacial activity or volcanic deposition.
Centripetal
The centripetal drainage pattern is just the opposite of the radial as streams flow toward a central depression. This pattern is typical in the western and southwestern portions of the United States where basins exhibit interior drainage.
Trellised
It is a rectangular shaped drainage pattern that develops where bands of rocks vary in resistance. In some areas there are alternate bands of hard and soft rocks. The flowing water can erode the soft rocks and thus flows along the bands of soft rock. Many such water channels form a trellis.
