Ques 26. Which of the following ports is located on estuary? A. Kandala B. Marmagao C. Kolkata-Haldia D. Tuticorin
Ans, A EXPLANATION O A sudden, downpour over a limited area as if the entire clouds were to rain down in a matter of minutes. If it rains over a 100 mm in an hour concentrated in a area just a few square kilometres, one can call it a cloudburst. cloudbursts occur because the warm air current from the ground or below the clouds rushes up and carries the falling raindrops up with it The rain fails to fall down in a steady shower. This results in excessive condensation in the clouds as new drops form and old drops are pushed back into it by the updraft. Then one of them gives in. The air current slows down or the clouds can't hold. The resulting violent downpour can dump as much as 7o,ooo tonnes of water over an acre of land. O O In India, a cloudburst mostly occurs in the mountains of India where the low monsoon clouds are stopped by the high mountains. But it may happen elsewhere. On July 26, 2005, a cloudburst over Mumbai dumped 1,448 mm of rain in 1o hours. ource:Indiatoday.in
