\nThey lie along the Arabian sea.<\/p>\n They mark the western edge of the Deccan plateau.<\/p>\n They are continuous and can be crossed through the passes only.<\/p>\n They are higher than the Eastern Ghats. Their average elevation is 900-1600 metres.<\/p>\n They cause orographic rain mostly in summer due to the summer monsoons. The climate is hot and moist.<\/p>\n They have highly fertile soil, rice, spices, rubber, coconuts, cashew nuts, etc. are grown here.<\/td>\n | They lie along the Bay of Bengal.<\/p>\n They mark the eastern edge of the Deccan plateau.<\/p>\n They are discontinuous, irregular and dissected by rivers draining into the Bay of Bengal.<\/p>\n They are lower than the Western Ghats. Their average elevation is 600 metres.<\/p>\n They cause rain mostly in winter through North-eastern monsoon. However, rain here is lesser than the western strip.<\/p>\n They have less fertile soil.

Its northern part was the Angara land and the southern part was the Gondwana land.<\/p>\n (ii) The convectional currents split the crust into a number of pieces, thus leading to the drifting of the Indo-Australian plate after being separated from the Gondwana land, towards north.<\/p>\n (iii) The northward drift resulted in the collision of the plate with the much larger Eurasian plate. Due to this collision, the sedimentary rocks which were accumulated in the geosyncline known as the Tythes were folded to form the mountain system of western Asia and Himalaya.<\/p>\n Question 5. \nWhich are the major physiographic divisions of India? Contrast the relief of the Himalayan region with that of the Peninsular plateau. \nAnswer: \nThe major physiographic divisions of India are:<\/p>\n |
