Answer 2

The rivers in the northern plains have water even in summer because the rivers of the Northern Plains such as Ganga begins as Bhagirathi from an iceberg named Gangotri, in the Himalayas. These rivers have water even in summer because the rivers are created in the Himalayas which are capped with a sleet of snow and ice. The snow and ice dissolves during summer and the water flow into the streams.
