The northern part of the eastern coast

Explanation

The Coastal Plains of India are broadly divided into the Western Coastal Plains and the Eastern Coastal Plains. These plains are further subdivided into regional units based on their location.

The Eastern Coastal Plains:

• The Eastern Coastal Plain stretches along the Bay of Bengal from West Bengal to Tamil Nadu.
• It is regionally divided into two major parts:
  • The Northern Circars: This refers to the northern part of the eastern coast, extending roughly from the Mahanadi River to the Krishna River.
  • The Coromandel Coast: This refers to the southern part of the eastern coast, extending from the Krishna River to Kanyakumari.

Comparison with the Western Coast:

• The northern part of the western coast is known as the Konkan Coast.
• The central part is the Kannad Plain.
• The southern part is the Malabar Coast.

Key Takeaway: The Northern Circars constitute the northern segment of the Eastern Coastal Plains, while the southern segment is known as the Coromandel Coast.
