    Deltas are common in India for the East-flowing river systems, whereas they are nearly absent on the West coast, because West-flowing rivers   [2010-I]             

    A)  are few

    B)  have lesser water volume and carry less run-off silt

    C)  originate in dry areas

    D)  originate largely in the Western Ghats and have short distance to cover to the sea

    Correct Answer: B

    Solution :

     Most of the Western flowing rivers travel lesser distance than eastern flowing rivers before gelling into the sea. On way to Western coast through hard rocks and over higher gradient, they collect large amount of Slit and flow with very high speed compared to East flowing rivers. Eastern rivers flow through broken hills and mountain ranges. So, they are widened and (low with lesser velocity before entering into sea. So, they deposit sediments and silt before entering into sea and can form a Delta.
