Difficulty: MediumPhysiography and Relief Features of India

Which of the following relief characteristics distinguishes the Western Coastal Plain from the Eastern Coastal Plain of India?

  1. A
    The Western Coastal Plain is significantly broader and features vast deltas formed by major peninsular rivers.
  2. The Western Coastal Plain is a narrow submerged coast providing favorable natural conditions for port development.Answer
  3. C
    The Eastern Coastal Plain is formed primarily by glacial erosion and completely lacks alluvial deposits.
  4. D
    The Eastern Coastal Plain is extremely narrow and devoid of any coastal lagoons or lakes.

Answer

The Western Coastal Plain is a narrow submerged coast providing favorable natural conditions for port development.
The Western Coastal Plain is a submerged coastline. Because of this submergence, it is narrow in width and provides deep natural indentations ideal for natural harbors and port development. In contrast, the Eastern Coastal Plain is an emergent coast, broader, and dominated by deltaic formations.

Step-by-Step Solution

1
Analyze the geological origin and coast type of the Western Coastal Plain.
The Western Coastal Plain of India is an example of a submerged coastal plain, which makes it narrow and indented.
Submergence provides deep water along the coastline suitable for natural ports and harbors.
2
Compare the feature with the Eastern Coastal Plain.
The Eastern Coastal Plain is an emergent coast, much broader, and characterized by large river deltas (Mahanadi, Godavari, Krishna, Kaveri).
Emergent coasts tend to develop broad alluvial plains rather than narrow submerged inlets.
