Analyzing Statements on the Western Coastal Plain of India

Let's examine each statement regarding the western coastal plain of India to determine which ones are correct.

Understanding the Western Coastal Plain

The western coastal plain is a strip of land between the Western Ghats and the Arabian Sea. It stretches from Gujarat in the north down to Kerala in the south. Compared to the eastern coastal plain, it has some distinct characteristics.

Detailed Analysis of Statements

Statement 1: It is a narrow belt.

The western coastal plain is generally narrower than the eastern coastal plain. Its average width ranges from 10 to 25 km. This narrowness is a defining feature compared to the broader eastern plain.

This statement is correct.

Statement 2: It is an example of the submerged coastal plain.

Geologically, the western coastal plain is believed to be a submerged landmass. This submergence has resulted in a relatively straight coastline with few indentations compared to other types of coasts, although submergence does create favorable conditions for ports as discussed below.

This statement is correct.

Statement 3: It provides natural conditions for development of ports.

While statement 2 mentions a relatively straight coastline, the submerged nature actually creates several natural harbours and inlets along the western coast due to the irregular shape of the submerged land. Cities like Mumbai, Kochi, and Kandla are examples of major ports located on the western coast, benefiting from these natural conditions.

This statement is correct.

Statement 4: It has well-developed deltas.

The rivers flowing westward from the Western Ghats are short, swift, and seasonal. They do not carry large amounts of sediment and erode rocks near their source. When they reach the Arabian Sea, they often form estuaries rather than deltas. Well-developed deltas, such as the Ganga, Mahanadi, Godavari, Krishna, and Cauvery deltas, are characteristic features of the eastern coastal plain where larger, perennial rivers flow into the Bay of Bengal.

This statement is incorrect.

Summary of Findings

Based on the analysis:

• Statement 1 (narrow belt) is correct.
• Statement 2 (submerged coastal plain) is correct.
• Statement 3 (natural conditions for ports) is correct.
• Statement 4 (well-developed deltas) is incorrect.

Therefore, the statements that are correct are 1, 2, and 3.

Revision Table: Western vs Eastern Coastal Plains

Additional Information on Coastal Plains of India

The coastal plains of India are divided into two parts: the Western Coastal Plain and the Eastern Coastal Plain. Both are important physiographic divisions, but they differ significantly due to their formation and the nature of the rivers flowing through them.

The western coastal plain is further divided into sections:

• The Kathiawar and Gujarat plains in the north.
• The Konkan coast in the middle (from Mumbai to Goa).
• The Malabar Coast in the south (from Goa to Kanyakumari).

The eastern coastal plain is also divided:

• The Utkal coast in the north (Odisha).
• The Andhra coast in the middle (Andhra Pradesh).
• The Coromandel Coast in the south (Tamil Nadu).

Understanding the characteristics of these plains is crucial for studying the geography of India.
