Explanations:
The question asks about the regions in Bharat (India) that experience low rainfall and are prone to drought conditions. To understand this, it is essential to consider the geographical and climatic factors that influence rainfall patterns across different regions of India.
Rajasthan, located in the northwestern part of India, is known for its arid and semi-arid climate. The state is characterized by low rainfall, with an average annual rainfall of around 600 mm, which is significantly lower than the national average. The primary reason for this low rainfall is the state's geographical location and topography. Rajasthan is situated in the rain shadow region of the Aravalli Range, which blocks the monsoon winds from the Arabian Sea, resulting in a scarcity of moisture.
The state's climate is predominantly influenced by the monsoon winds, which are the primary source of rainfall in India. However, due to its location, Rajasthan receives only a fraction of the monsoon rains compared to other parts of the country. The monsoon winds, which bring moisture from the Arabian Sea, are obstructed by the Aravalli Range, leading to a significant reduction in rainfall in the western and central parts of the state. This results in a semi-arid to arid climate, with frequent drought conditions, especially in the western and central regions of Rajasthan.
In contrast, Gujarat, located to the west of Rajasthan, also experiences low rainfall but has a more varied climate due to its coastal regions. The coastal areas of Gujarat receive more rainfall compared to the interior regions, which are more arid. However, Gujarat is not as consistently drought-prone as Rajasthan.
Bihar, located in the eastern part of India, has a subtropical humid climate and receives a significant amount of rainfall, primarily from the monsoon winds. The state's average annual rainfall is around 1,200 mm, which is much higher than that of Rajasthan. Therefore, Bihar is not typically considered a drought-prone region.
Telangana, located in the southern part of India, has a tropical climate with a mix of dry and humid conditions. The state receives moderate rainfall, with an average annual rainfall of around 800 mm. While Telangana does experience drought conditions at times, it is not as consistently drought-prone as Rajasthan.
In summary, Rajasthan is the correct answer because it is the region in Bharat that experiences consistently low rainfall and is frequently affected by drought conditions due to its geographical location and topography.
