Explanations:The Tropic of Cancer is a significant line of latitude that runs at approximately 23.5 degrees North. This line marks the northernmost point where the sun can be directly overhead at noon, which occurs during the summer solstice. The Tropic of Cancer is an important geographical boundary that separates the tropical and subtropical climate zones from the temperate zones in the Northern Hemisphere.
Understanding the position of cities relative to the Tropic of Cancer is crucial for geographical studies. The Tropic of Cancer runs through several countries, including India, and divides the country into two distinct regions: the region north of the Tropic of Cancer and the region south of it. Cities located north of the Tropic of Cancer experience a more temperate climate, while those south of it are generally in the tropical or subtropical climate zones.
Among the options provided, Guna, Madhya Pradesh, Delhi, and Jaipur, Rajasthan are all located north of the Tropic of Cancer. These cities experience a temperate climate with distinct seasons, including hot summers and cold winters. On the other hand, Kolkata, West Bengal, is located south of the Tropic of Cancer. This means that Kolkata experiences a tropical climate with high temperatures and significant rainfall throughout the year.
It is important to note that the Tropic of Cancer is not a fixed line but gradually shifts over time due to the Earth's axial precession. However, for the purpose of geographical studies and examinations, the Tropic of Cancer is considered to be at 23.5 degrees North latitude. This knowledge helps in understanding the climatic conditions and geographical features of different regions in India and around the world.
