Which of the following rivers rise from the Eastern Ghats?
1. Hemavathi
2. Nagavali
3. Malaprabha
4. Vamsadhara

Correct option is D

The correct answer is (d) 2 and 4 only

Explanation:

• Hemavathi: The Hemavathi river originates from the Western Ghats, not the Eastern Ghats. This eliminates it from being part of the rivers that rise from the Eastern Ghats. However, it is an important river flowing through Karnataka.
• Nagavali: The Nagavali river originates from the Eastern Ghats, specifically from the Visakhapatnam region in Andhra Pradesh. So, this is a river that rises from the Eastern Ghats.
• Malaprabha: The Malaprabha river originates from the Western Ghats near the town of Sankeshwar in Karnataka. Therefore, it is not part of the rivers that rise from the Eastern Ghats.
• Vamsadhara: The Vamsadhara river also rises from the Eastern Ghats, originating in the Kalahandi district of Odisha. It flows through Odisha and Andhra Pradesh.

East Coast of India:

• Geography: The East Coast is characterized by expansive and flat plains along the Bay of Bengal. It is wider than the western coast and is considered an emergent coast, meaning it is slowly rising out of the sea.
• Divisions:
• Northern Circar: Refers to the northern part of the eastern coastline.
• Coromandel Coast: Refers to the southern part of the eastern coastline.
• Delta Formation:
• The eastern rivers such as Mahanadi, Godavari, Krishna, and Kaveri form extensive deltas along the coastline.
• Ports:
• The eastern coast has fewer ports and harbours compared to the western coast, mainly due to its emergent nature.
• Continental Shelf:
• Extends up to 500 kilometres into the Bay of Bengal, making it more challenging to develop major ports and harbours.
• Monazite Distribution:
• Monazite, a mineral rich in rare earth and thorium, is primarily found in states like Kerala, Tamil Nadu, Odisha, Andhra Pradesh, Maharashtra, Gujarat, and inland areas of Jharkhand, West Bengal, and Tamil Nadu.

West Coast of India:

• Geography: The western coastal plains stretch from Gujarat in the north to Kerala in the south, passing through Maharashtra, Goa, and Karnataka. These plains are narrower and more rugged compared to the eastern plains.
• Coastal Nature:
• The western coast is a submerged coastal plain, which influences its geography and makes it suitable for natural harbour development.
• Width of the Plains:
• The plains narrow in the center and widen towards the northern and southern ends of the coast.
• Rivers:
• Unlike the eastern coast, rivers flowing through this region do not form deltas.
• Natural Harbours:
• Due to submergence, the western coast provides ideal natural conditions for developing ports and harbours.
