Geography
The Coastal Plains and Islands
तटीय मैदान और द्वीप
In this Class 9 Geography topic from Physical Features of India, students explore how India’s coastal plains and islands were formed and how they differ in location, relief, and physical features. They study the Western Coastal Plain along the Arabian Sea and the broader Eastern Coastal Plain along the Bay of Bengal, including important rivers, deltas, lagoons, and coastal processes. The topic also introduces the Andaman and Nicobar Islands and Lakshadweep, highlighting their geographical setting, natural environment, and importance to India.
