Explanation: Tamil Nadu is one of the southern states of India, known for its rich cultural heritage, diverse geography, and significant contributions to Indian history and economy. Understanding the geographical layout of Tamil Nadu is essential for comprehending its regional dynamics and administrative divisions.
Tamil Nadu is bordered by several states and the Bay of Bengal. To the northwest, Tamil Nadu shares its border with the state of Karnatika. This border is significant as it delineates the administrative and cultural boundaries between the two states. Karnatika, also known as Karnataka, is a state in southern India that is known for its historical sites, natural beauty, and vibrant culture.
The other borders of Tamil Nadu are as follows:
- To the southwest, Tamil Nadu is bordered by Kerala, another southern state known for its lush green landscapes and backwaters.
- To the east, Tamil Nadu is bordered by the Bay of Bengal, which is a significant body of water that influences the state's climate and economy.
- To the northeast, Tamil Nadu shares its border with Andhra Pradesh, a state that was formed after the bifurcation of the old Andhra Pradesh state in 2014.
It is important to note the specific directions of these borders to avoid confusion. For instance, students might mistakenly think that Kerala is to the northwest of Tamil Nadu, but it is actually to the southwest. Similarly, Andhra Pradesh is to the northeast, not the northwest.
Understanding these geographical details is crucial for students preparing for competitive examinations such as the TNPSC, UPSC, and other state PSCs, where questions on state boundaries and regional geography are common. This knowledge also helps in understanding the cultural, economic, and political interactions between these states.
In summary, the northwest border of Tamil Nadu is shared with Karnatika, making it the correct answer to the question. This geographical fact is a key part of understanding the layout of southern India and the relationships between its states.
