Question

Describe DENDRITIC,TRELLIS, RECTANGULAR and RADICAL DRAINAGE SYSTEM in about 60-80 words

Answer 1

Dendritic Drainage. A dendritic drainage pattern occurs when the tributary systems subdivides headway like the limbs of a tree. These patterns usually form in horizontal sedimentary or in intrusive igneous rocks where the rock mass is reasonably homogeneous. A trellis drainage pattern occurs where subparallel streams erode a valley along the strike of less resistant formations. A drainage pattern in which the main streams and their tributaries display many right-angle bends and exhibit sections of approx. the same length; it is indicative of streams following prominent fault or joint systems that break the rocks intorectangular blocks. A radial drainage pattern occurs when the tributaries flow radially outward and downward from a central topographic high. This type of pattern is typical of volcanic cones, isolated hills, and elevated domes.

Answer 2

The dendritic pattern develops where the river channel follows the slope of the Terrain the stream with its tributaries resembles the branches of a tree does the name dendritic .a river joined by its tributaries at approximately right angles develops a trellis pattern a trellis drainage pattern developed where hard and soft rocks exist parallel to each other. a rectangular drainage pattern develops on a strongly jointed Rocky Terrain .the radial pattern develops when stream flow in different directions from a central peak or dome like structure.
