India is basically a peninsula, with the Arabian Sea on the west, the Bay of Bengal on the east, and the Indian Ocean to the south.
The Himalayan Mountains separate India from much of the rest of Asia and China. The Himalayas have many of the tallest mountains in the world. The tallest mountain in India is the Kanchenjunga at 28, 208 feet.
Just south of the Himalayas is the Indo-Gangetic Plain which lies between the Indus and Ganges rivers. On the north-western end of India is the Thar desert. Most of southern India is the Deccan Plateau, which is mostly rolling hills with many rivers. The plateau is separated from the northern plain by the Vindhya mountains. The Eastern and Western Ghats are coastal mountains on either side of the plateau.
