उत्तर
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.
