Multiple choice

Match the following columns:

 
Drainage patterns Characteristics
a. Dendritic 1. Rivers originate from a hill and flow in all directions.
b. Radial 2. Rivers discharge their waters from all directions in a lake or depression.
c. Trellis 3. Resembling the branches of a tree
d. Centripetal 4. Primary tributaries of rivers flow parallel to each other and secondary tributaries join them at right angles.

  1. a - 1, b - 3, c - 2, d - 4

  2. a - 2, b - 1, c - 4, d - 3

  3. a - 3, b - 4, c - 2, d - 1

  5. a - 2, b - 4, c - 3, d - 1
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

This is the correct matching. Dendritic pattern is resembling the branches of a tree. Radial pattern is where rivers originate from a hill and flow in all directions. Trellis pattern is where primary tributaries of rivers flow parallel to each other and secondary tributaries join them at right angles. Centripetal pattern is where rivers discharge their waters from all directions in a lake or depression.
