Question

Match List I with List - II.

List - I (Slope Zones by Miller)	List - II (Slope in degrees)
A. Waxing slope B. Free face slope C. Constant slope D. Waning slope	I. 34° 14' - 90° II. 14° 24' - 34° 14' III. 3° 35' - 14° 24' IV. 0° - 3° 35'

Choose the correct answer from the options given below:

• A. A-IV, B-III, C-II, D-I
• B. A-I, B-II, C-III, D-IV
• C. A-II, B-I, C-IV, D-III
• D. A-III, B-IV, C-I, D-II

Hint:

Waxing = Getting steeper; Waning = Getting flatter. Always associate Waning with the lowest degree value.

Answer 1

The Correct Option is B

Concept: Slope analysis in geomorphology identifies different segments of a hillside, often based on the classic models of Wood and King, later quantified by others like Miller.

Step 1: Defining the Slope segments.

• A. Waxing Slope (Crest): The convex upper part where steepness increases. Associated with the highest gradients in many models (A-I).
• B. Free Face (Scarp): The vertical or near-vertical rocky outcrop (B-II).
• C. Constant Slope (Debris Slope): A straight-line segment with uniform gradient (C-III).
• D. Waning Slope (Pediment): The concave lower part where the slope flattens out toward the base (D-IV).

Step 2: Ordering.
Following the sequence from top (steepest) to bottom (flattest) aligns with A-I, B-II, C-III, D-IV.
