Explanation: Latitude is a fundamental concept in geography that helps us understand the position of a place on the Earth's surface relative to the equator. The equator is the reference line at 0$^\circ$ latitude, and all other latitudes are measured in degrees north (N) or south (S) of this line.
Tamil Nadu, a state in southern India, is located entirely in the northern hemisphere. This means that all of its latitudinal coordinates are positive (north) values. The latitudinal extent of Tamil Nadu spans from approximately 8$^\circ$4' N to 13$^\circ$35' N. This range indicates that the northernmost part of Tamil Nadu is at about 13$^\circ$35' N, while the southernmost part is at about 8$^\circ$4' N.
Understanding the latitudinal extent of a region is important for various reasons, including climate studies, agricultural planning, and navigation. The latitudinal extent of a place can influence its climate, as regions closer to the equator generally experience warmer temperatures and different weather patterns compared to regions farther from the equator.
In the context of Tamil Nadu, the latitudinal extent helps explain why the state has a tropical climate with distinct wet and dry seasons. The northern part of the state, being closer to the Tropic of Cancer, experiences a more tropical climate, while the southern part, being slightly farther from the equator, may have slightly cooler temperatures.
It is important to note that the latitudinal extent of a state or country is a fixed geographical fact and does not change over time. Therefore, when answering questions about the latitudinal extent of Tamil Nadu, it is crucial to recall the correct values and ensure that the coordinates are in the northern hemisphere, as Tamil Nadu is located entirely north of the equator.
In summary, the correct latitudinal extent of Tamil Nadu is from 8$^\circ$4' N to 13$^\circ$35' N, which reflects its position in the northern hemisphere and its geographical boundaries. This information is essential for understanding the state's climate, geography, and location within the broader context of India and the world.
