In Indian Geography part, we will study the physiography of India. We will start with the geological structure of a country which will provide a basic idea about the characteristics of rocks, soils and minerals. Geologically, the subcontinent of India was a part of the Gondwanaland (the Southern Continent).  The peninsular part of India is oldest landmass since the formation of the Earth’s crust while the Himalayan and mountain chains around it are young landscapes. The northern plains lying below the mountain chains provide suitable conditions for agriculture. We will also study the river system, climate, natural vegetation and wildlife of India.
