India, located in South Asia, is the seventh-largest country by area and the most populous in the world. Its capital is New Delhi. India's geography is incredibly diverse, bounded by the Indian Ocean to the south, the Arabian Sea to the southwest, and the Bay of Bengal to the southeast. It shares land borders with Pakistan, China, Nepal, Bhutan, Myanmar, and Bangladesh. The northern border is defined by the Himalayas, the world's highest mountain range. South of the mountains lies the Indo-Gangetic Plain, a fertile region formed by the Ganges and Indus rivers. The western part features the Thar Desert, while the southern peninsula is dominated by the Deccan Plateau, flanked by the Western and Eastern Ghats mountain ranges. India's climate is dominated by the monsoon system, which brings vital seasonal rains. It is one of the world's seventeen megadiverse countries, hosting a vast array of flora and fauna, including the Bengal tiger and Indian elephant.
