_________ profiles present a vivid picture of the magnitude of relief and the general nature of dissection of the region or watershed.

Correct option is D

Introduction

A composite profile is a generalized relief profile prepared by combining several cross-sections of a region or watershed. It gives an overall representation of the terrain, highlighting the magnitude of relief and the degree of dissection.

Information Booster

(D) Composite ✔ (Correct Answer)

• A composite profile combines several relief profiles into one generalized profile.
• It provides:
  • Overall relief characteristics
  • Magnitude of elevation differences
  • Nature and intensity of dissection
  • General topographic character of a region or watershed

Therefore, it presents the best overall picture of regional relief.

✔ Correct Answer

Why the other options are incorrect?

(A) Cross Profile ✘

• Shows the relief along a single line.
• Represents only one section of the terrain, not the overall relief.

(B) Superimposed Profile ✘

• Used to compare two or more profiles on the same base line.
• Not primarily meant to represent the overall dissection of a watershed.

(C) Projected Profile ✘

• Constructed by projecting the highest points onto a profile line.
• Mainly used to study skyline or intervisibility, not the general nature of dissection.
