Question

Which one of the following drainage patterns is formed by stream paths that follow circular segments?

• A. Annular
• B. Trellis
• C. Radial
• D. Centripetal

Hint:

Annular drainage patterns occur when streams follow circular or ring-like paths, typically formed around volcanic or domal structures.

Answer 1

The Correct Option is A

Step 1: Understand the Types of Drainage Patterns.
Drainage patterns are determined by the underlying geological structure, such as the type of rock or the topography of the area. Some common drainage patterns include:
- Annular: Formed by stream paths that follow circular segments, often found in areas with concentric ring structures, such as volcanic domes.
- Trellis: Found in regions with alternating hard and soft rock, where streams follow the valleys formed by the soft rock.
- Radial: Streams radiate outward from a central high point, such as a mountain or a volcano.
- Centripetal: Streams converge toward a central low point, typically forming in basin-shaped regions.
Thus, the correct answer is (A) Annular. Final Answer: \[ \boxed{\text{Annular}} \]
