Class 7 Social Science Chapter 1 Geographical Diversity of India question answer
Satellite images often show bright lights over northern plains like the Ganga Basin. This is due to high population density, urbanization and agriculture-based economies. The flat land allows easy construction of roads, houses and industries. People live closer together, using electricity for homes, streetlights and factories. Unlike mountainous or forested regions with fewer settlements, plains support more infrastructure. This results in dense clusters of lighting, especially visible during nighttime from space.
