{'soil': [7, 0, 4, 7], 'erosion': [3, 0, 0, 3], 'northern plains': [3, 0, 1, 3], 'aggradation': [1, 0, 2, 0], 'degradation': [3, 1, 1, 3], 'weathering': [4, 0, 1, 11], 'india': [8, 1, 7, 13]}

The correct answer is option 2: aggradation. Aggradation refers to the process of soil formation through the deposition of sediments. In the case of the northern plains of India, this soil has been formed by the deposition of sediments brought by rivers such as the Ganga, Brahmaputra, and Indus. These rivers carry a large amount of sediment from the Himalayas and deposit it in the plains, leading to the formation of fertile alluvial soil. This soil is rich in nutrients and is highly suitable for agriculture. Therefore, the soil in the northern plains of India is primarily a result of aggradation, rather than degradation (option 1), weathering in situ (option 3), or erosion (option 4).
