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.

Eurasia is a massive landmass combining the continents of Europe and Asia. It stretches from the Atlantic Ocean in the west to the Pacific in the east. India is located on the Indian Plate, which collided with the Eurasian Plate, resulting in the formation of the Himalayas. Eurasia includes powerful nations like Russia, China and Germany. Understanding Eurasia helps in grasping geological events, continental drift and India’s unique position at the crossroads of ancient and modern civilizations.

Sand dunes are hills of loose sand formed by wind action in deserts. They usually appear in crescent, dome or linear shapes depending on wind direction and speed. A typical dune has a gentle windward side and a steep leeward side. These shapes aren't fixed and can move or grow over time. The Thar DeRead more
Sand dunes are hills of loose sand formed by wind action in deserts. They usually appear in crescent, dome or linear shapes depending on wind direction and speed. A typical dune has a gentle windward side and a steep leeward side. These shapes aren’t fixed and can move or grow over time. The Thar Desert has many such dunes, which help geographers understand wind patterns and natural landscape evolution in arid environments.

Though made of loose sand, dunes form mountain-like shapes due to wind erosion and deposition. Winds blow sand in one direction, building up a gentle slope on the windward side and a steep slope on the leeward side. This process mimics how mountains look, but unlike mountains, dunes are not fixed—thRead more
Though made of loose sand, dunes form mountain-like shapes due to wind erosion and deposition. Winds blow sand in one direction, building up a gentle slope on the windward side and a steep slope on the leeward side. This process mimics how mountains look, but unlike mountains, dunes are not fixed—they shift and reshape over time. This similarity in shape is a result of natural forces sculpting landforms, whether hard like rock or soft like sand.

As you move east from the Thar Desert, you will spot the Aravalli Hills stretching across Rajasthan, Haryana, Delhi and Gujarat. These hills are ancient, worn-down ranges that run in a northeast to southwest direction. Though not very high, the Aravallis play a crucial ecological role by preventing desertification from spreading into the fertile plains. They are rich in minerals and home to historical forts, wildlife sanctuaries and sacred groves, reflecting both geological and cultural heritage.
