Explanation: The Earth is divided into different latitudinal zones based on the angle of the sun's rays. The most significant zones are the Tropical Zone, the Subtropical Zone, the Temperate Zone, and the Polar Zone. The Tropical Zone is defined as the region between the Tropic of Cancer (23.5°N) and the Tropic of Capricorn (23.5°S). This zone experiences high temperatures and high humidity throughout the year due to the direct or near-direct sunlight.
In the context of Indian states, several states are located within the Tropical Zone, but not all of them lie entirely within this zone. Gujarat, for example, extends beyond the Tropic of Cancer into the Subtropical Zone. The northern part of Gujarat, including cities like Ahmedabad and Gandhinagar, is located in the Subtropical Zone, which is characterized by cooler temperatures and less humidity compared to the Tropical Zone.
To understand why Gujarat is the correct answer, it is essential to consider the geographical boundaries of the state. Gujarat's southern part, including cities like Surat and Rajkot, is located within the Tropical Zone. However, the northern part of the state extends beyond the Tropic of Cancer, placing it in the Subtropical Zone. This makes Gujarat the only state among the given options that does not lie entirely within the Tropical Zone.
In contrast, states like Kerala, Tamil Nadu, Karnataka, Maharashtra, and Andhra Pradesh are all located entirely within the Tropical Zone. These states lie between the Equator and the Tropic of Cancer, experiencing the characteristic high temperatures and humidity of the Tropical Zone throughout the year.
Understanding the latitudinal zones and their impact on climate is crucial for comprehending the geographical and climatic characteristics of different regions. This knowledge is particularly important for students preparing for competitive examinations that test geographical knowledge, such as the Gujarat Public Service Commission, UPSC Civil Services, and other State PSC Exams.
