Explanations:The density of a railway network is influenced by several factors, including the geographical and climatic conditions of a region. Arid regions, characterized by low rainfall and sparse vegetation, often have less dense railway networks due to the challenging terrain and lower population density. Rajasthan, located in the northwestern part of India, is known for its arid and semi-arid regions, particularly in the western part of the state. The Thar Desert, which covers a significant portion of Rajasthan, is one of the largest deserts in the world and presents a challenging environment for the development of a dense railway network.
The arid conditions in Rajasthan result in sparse population distribution, which reduces the demand for extensive railway infrastructure. Additionally, the harsh terrain and low rainfall make the construction and maintenance of railway lines more difficult and costly. As a result, the railway network in Rajasthan is less dense compared to other states with more favorable climatic conditions and higher population densities.
It is important to understand that the density of a railway network is not solely determined by the climatic conditions but also by the economic and social needs of the region. However, in the context of this question, the arid conditions of Rajasthan play a significant role in explaining the less dense railway network.
Other states mentioned in the options, such as Goa, Karnataka, and Maharashtra, have different climatic conditions and geographical features that do not align with the characteristics of an arid region. Goa, for example, has a tropical monsoon climate with high rainfall, which does not support the idea of a less dense railway network. Karnataka and Maharashtra have a mix of climatic zones, but they do not predominantly consist of arid regions, and thus their railway network densities are not significantly less compared to other states.
In summary, the less dense railway network in Rajasthan is primarily due to its arid and semi-arid regions, which present challenging conditions for railway infrastructure development. This understanding is crucial for comprehending the geographical and climatic factors that influence the distribution of railway networks in different regions of India.
