Describe each of the following drainage patterns.
i)Dendritic pattern.
ii)Trellis pattern.

Answer:

i)-Developed in areas where rocks have uniform structures. The direction of
flow is influenced by the slope of the land. The tributaries coverage on the
main river forming a shape like that of tree and its branches.

ii)The pattern develops where soft and hard rocks alternate vertically. The
tributaries join the main river at acute angles. The consequent stream flow to opposite direction of the main river. The main river and its tributaries form a
rectilinear pattern
