Class 7 Social Science Textbook Chapter 1 Geographical Diversity of India Question Answer
During summer, the Brahmaputra River swells in size due to the melting of Himalayan glaciers and increased rainfall in the eastern region. As temperatures rise, snow and ice from mountains melt rapidly, releasing a vast amount of water into the river. Unlike other rivers that reduce in volume during summer, the Brahmaputra becomes larger, often leading to floods. This increase supports agriculture and wetlands but also poses challenges like erosion and displacement for people living along its banks.
