Explanation: Cyclones are powerful atmospheric systems that form over warm ocean waters and can cause significant damage when they make landfall. The likelihood of a cyclone affecting a particular area depends on several factors, including the geographical location, proximity to the ocean, and the typical cyclone paths in the region.
Delhi, the correct answer, is located far inland in northern India, away from the coast. It is situated in the northern part of the country, far from the Bay of Bengal and the Arabian Sea, which are the primary sources of cyclones in India. Due to its inland location, Delhi is not typically in the path of cyclones and is therefore the least likely to be affected by them.
Orissa, on the other hand, is a coastal state in eastern India, bordering the Bay of Bengal. This region is frequently affected by cyclones, particularly those that form in the Bay of Bengal. The warm waters of the Bay of Bengal provide the necessary conditions for cyclone formation, and Orissa's coastal location makes it highly vulnerable to these storms.
Chennai, a major coastal city in Tamil Nadu, is also frequently affected by cyclones. Like Orissa, Chennai is located on the eastern coast of India and is often in the path of cyclones that originate from the Bay of Bengal. The city's coastal location makes it susceptible to the strong winds and heavy rainfall associated with cyclonic storms.
West Bengal, another coastal state in eastern India, is also frequently affected by cyclones. Similar to Orissa, West Bengal is located along the Bay of Bengal, which is a common source of cyclones. The state's proximity to the coast makes it vulnerable to the destructive forces of cyclonic activity.
In summary, the geographical location of Delhi, being far inland and away from the coast, makes it the least likely to be affected by cyclones compared to the other options. Understanding the geographical and climatic factors that influence cyclone formation and movement is crucial for assessing the vulnerability of different regions to these natural disasters.
