Question

The Type of drainage pattern usually found on maturely dissected dome structures encircled with alternate weak and hard rocks:

• A. Centripetal pattern
• B. Annular pattern
• C. Parallel pattern
• D. Radial pattern

Answer 1

Answer:

B. Annular pattern

• Annular drainage pattern is typically found on maturely dissected dome structures encircled with alternate weak and hard rocks.

This pattern is characterized by

• Streams flowing in a circular or ring-like pattern around the dome.

• Drainage channels forming a concentric pattern, with outer streams flowing away from the center.

• Alternate weak and hard rocks creating a series of circular or arc-shaped valleys and ridges.

Examples:

• Appalachian Mountains (USA)

• Ozark Plateau (USA)

• Scottish Highlands (UK)

• Himalayan foothills (Asia)
