Explanations:The Eastern Coastal Plains are a significant geographical feature of India, extending along the eastern coast from West Bengal in the north to Tamil Nadu in the south. This region is characterized by its low-lying terrain and is an important agricultural and industrial area. The plains are part of the larger coastal plains of India, which are divided into two main sections: the Western Coastal Plains and the Eastern Coastal Plains.
The Eastern Coastal Plains are formed by the alluvial deposits of the Ganga, Brahmaputra, Mahanadi, Godavari, Krishna, and Kaveri rivers. These rivers flow from the Himalayas and the Eastern Ghats, depositing silt and creating a fertile plain along the coast. The plains are divided into two parts: the Northern Circars in the north and the Coromandel Coast in the south. The Northern Circars extend from the Mahanadi delta to the Krishna delta, while the Coromandel Coast extends from the Krishna delta to the Kaveri delta.
The Eastern Coastal Plains are an important agricultural region, with a variety of crops grown, including rice, sugarcane, coconut, and cashew. The region is also known for its fishing industry and has several important ports, such as Kolkata, Visakhapatnam, Chennai, and Tuticorin. The plains are also home to several important cities and industrial centers, including Kolkata, Visakhapatnam, Vijayawada, and Chennai.
It is important to note that the Eastern Coastal Plains do not extend from Goa and Kanyakumari, as these locations are on the Western Coast of India. Similarly, the plains do not extend from Gujarat to Goa, as both of these states are located on the Western Coast. The correct geographical extent of the Eastern Coastal Plains is from West Bengal to Tamil Nadu, covering a significant portion of the eastern coast of India.
