Explanation: The Palk Strait is a significant geographical feature that separates the southeastern coast of Tamil Nadu, India, from the northwestern coast of Srilanka. It is a narrow body of water that connects the Bay of Bengal to the Gulf of Mannar and the Arabian Sea. The strait is approximately 50 to 80 kilometers wide and is an important maritime route for trade and transportation between the two countries.
The Palk Strait is named after the British naval officer Robert Palk, who served as the Governor of Madras (now Chennai) in the late 18th century. The strait is characterized by shallow waters and numerous sandbanks, which can make navigation challenging. Despite these challenges, the Palk Strait remains a vital waterway for both commercial and fishing vessels.
The geographical location of the Palk Strait is crucial for understanding the maritime boundaries and trade routes in the region. It is part of the larger Indian Ocean and plays a significant role in the economic and cultural exchanges between India and Srilanka. The strait is also home to diverse marine life and is an important area for fishing activities.
In the context of Tamil Nadu's geography, the Palk Strait is a key feature that defines the state's maritime boundary with Srilanka. It is essential for students to understand the location and significance of the Palk Strait to grasp the broader geographical and economic context of the region.
Other straits mentioned in the options, such as the Cook Strait, Torres Strait, and Davis Strait, are located in different parts of the world and are not related to the geographical boundary between Tamil Nadu and Srilanka.
