Answer 1

Dendritic trellis rectangular and radial

Answer 2

$\huge{\underline{\mathfrak{Drainage\:Patterns}}}$

There are basically 4 types of drainage patterns :

• Dendritic Pattern : This pattern is the most common pattern followed by rivers like Ganga. This develops where the river channel flows the slope of terrain. This stream with its tributaries resembles the branches of a tree.
• Trellis Pattern : In this pattern, short tributaries meet long trunk streams at near right angles. They are formed on sedimentary rocks of different resistance to erosion. An example is the Narmada river.
• Rectangular Pattern : In this type of pattern, straight tributaries meet straight trunk streams with bends at almost right angles. These are formed on faulted or fractured bedrock.
• Radial Pattern : In this pattern, the stream flows outward from a well defined central point like a volcano or other round uplift of land.
