Question

Rajasthan is a desert state in India. Once while travelling to Rajasthan by train, Boojho observed several streams and rivulets of rainwater during the journey but to his surprise, he did not see streams of water in the desert region even during rains. Help Boojho find a suitable explanation for this.

Answer 1

Deserts are vast stretches of sandy soil. In sandy soil, due to the presence of large spaces between the sand particles, the water drains out quickly. Therefore, sandy soil cannot hold much water and tends to be light and dry. It is because of this reason that in deserts, the falling rainwater immediately percolates downwards in the spaces between sand particles. Due to this, Boojho did not see streams of water in the desert region.
