Give a geographical reason for each of the following:

(i) The rivers of south India are less suitable for irrigation than the rivers of north India.

(ii) The Peninsular Plateau of India is considered to be a part of Gondwanaland hundreds of millions of years ago.

(iii) The Narmada and Tapi do not form deltas.

(i) The rivers of south India are less suitable for irrigation than the rivers of north India because rivers of north India are perennial as they are snow fed but the rivers of south India are seasonal as they are rain fed.

(ii) The Peninsular Plateau of India is considered to be a part of Gondwanaland hundreds of millions of years ago because due to the tectonic movements, the Indo Australian plate drifted after being separated from the Gondwana land towards the north. Moreover, the rocks that make up the plateau match those in Africa in age, type and the layer sequence in which they occur.

(iii) The Narmada and Tapi do not form deltas because they flow through hard rocks and are not able to form distributaries before they enter the Arabian sea.
