Explanations:The northern extremity of Tamil Nadu is marked by Pulicate lake, which is a significant geographical feature that defines the northern boundary of the state. Pulicate lake is located in the northernmost part of Tamil Nadu, near the border with Andhra Pradesh. This location is crucial for understanding the geographical layout of Tamil Nadu and its position within the broader context of South India.
Tamil Nadu is a state in southern India, and its boundaries are defined by several geographical features. The northern boundary of Tamil Nadu is shared with Andhra Pradesh, and Pulicate lake is one of the key landmarks that marks this boundary. The lake is situated in the northernmost part of the state, making it the northern extremity of Tamil Nadu.
It is important to note that the northern extremity of a state is not necessarily a city or a fort, but rather a geographical feature that marks the boundary. In the case of Tamil Nadu, Pulicate lake serves this purpose. Other landmarks such as Chennai, Thirupathi, and Vellore fort, while significant in their own right, do not mark the northern extremity of the state.
Understanding the geographical boundaries of a state is essential for various purposes, including administrative, political, and cultural contexts. For students preparing for competitive examinations, it is crucial to have a clear understanding of the geographical features that define the boundaries of different states in India. This knowledge helps in answering questions related to geography and regional studies accurately.
