Explanation: The Punjab region is a historical and cultural area located in the northwestern part of the Indian subcontinent, primarily in the Indus River basin. Historically, the region was a single entity, but it was divided during the partition of India in 1947, resulting in the creation of the Pakistani province of Punjab and the Indian state of Punjab.
The Punjab plains, which are part of the Indus River basin, are known for their fertile soil and are crucial for agriculture. These plains extend across both the Pakistani and Indian parts of Punjab, but the larger portion lies within the Pakistani province of Punjab. The Pakistani Punjab is significantly larger in area compared to the Indian state of Punjab, which explains why the larger part of the Punjab plains is in Pakistan.
The Indus River and its tributaries, such as the Ravi, Beas, and Sutlej, flow through these plains, making them highly productive for agriculture. The fertile alluvial soil deposited by these rivers has made the Punjab plains one of the most agriculturally productive regions in South Asia.
It is important to understand the historical context of the partition of Punjab in 1947, which led to the division of the region into two parts. The Pakistani province of Punjab is much larger in area and contains a larger portion of the fertile plains. The Indian state of Punjab, while also agriculturally significant, is smaller in size and contains a smaller portion of the plains.
In summary, the Punjab plains are a significant geographical feature of the Punjab region, and the larger part of these plains lies within the Pakistani province of Punjab. This is due to the historical division of the region and the geographical layout of the Indus River basin. Understanding this geographical and historical context is crucial for comprehending the distribution of the Punjab plains between India and Pakistan.
