1. Know the origin, location and boundary of India.

Origin- The name India (/'ɪndiə/) is derived from Indus, which is derived from the Old Persian word Hindu, from Sanskrit Sindhu, the historic local appellation for the Indus River.[10] The ancient Greeks referred to the ancient Indians as Indoi, the people of the Indus.[11] The Constitution of India and common usage in various Indian languages also recognise Bharat (pronunciation (info), IPA: [/bʰɑːrət̪/]) as an official name of equal status. Hindustan (/hin̪d̪ust̪ɑːn/ (info)), which is the Persian word for “Land of the Hindus” and historically referred to northern India, is also occasionally used as a synonym for all of India.
Location and Boundary- Located on the Indian subcontinent, India consists roughly of three major parts; in the north the massive Himalayas mountain range (with the highest point being the Kanchenjunga at 8,598 m) and the Indo-Gangetic plain (with deserts in the western end), and in the south the extensive Deccan plateau. The latter is part of a large peninsula in between the Bay of Bengal to the east and the Arabian Sea to the west, with both being part of the greater Indian Ocean.
India is home to several major rivers such as the Ganges, the Brahmaputra, the Yamuna, the Godavari and the Krishna. A small part of the upper course of the name-giving Indus lies within Indian territory.
