What is the Riddle of the Nile? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? What is the Riddle of the Nile? Perhaps you do not know that the great African river Nile has its own mystery. In any case, one circumstance concerning the great river has puzzled people for thousands of years. Every year, starting in July, the water level in the Nile begins to rise and in October it becomes 7,5 m higher than in May. During the flood season, the Nile overflows its banks and brings silt to the fields, which is an excellent fertilizer. This phenomenon - such a significant rise in water in the river - is very unusual, because in Egypt it almost does not rain! Therefore, for hundreds of years people have wondered what is the reason for the annual floods of the Nile. The answer to the "riddle of the Nile" was found only in the XIX century. The Nile is the longest river in the world. Its length from south to north is 6500 km. It flows mainly through the territory of Sudan and Egypt - states located in northwestern Africa. The annual floods of the Nile have created a fertile valley that runs like a narrow ribbon along the river, surrounded by a hot, arid, and barren desert. The first people settled in this valley many thousands of years ago. The Nile River is fed from two main sources - the White Nile and the Blue Nile. The White Nile flows out of Lake Victoria in Uganda. It has a calm, even flow and does not affect the change in the water level in the Nile. During April and May, when the Nile reaches its lowest point, 85 percent of it comes from the White Nile. What about the Blue Nile? It originates in the highlands of Ethiopia, where it rains heavily and snow melts in the mountains. When this rainy season comes, the amount of water in the Blue Nile increases dramatically and this causes the Nile to flood. So simply solved the riddle over which people have puzzled for so long. Author: Likum A. Random interesting fact from the Great Encyclopedia: How did some children's games come about? Nowadays, hide-and-seek is played for fun. But hide and seek appeared a long time ago, when this game had a completely different meaning for the people who played it. Adults usually played hide-and-seek. In some places in England there was a custom according to which, when spring came, people went out into the woods and fields to find there flowers and birds that appeared with the onset of this season. Then what was found was brought to the village so that everyone could see that spring had really come. The search for these signs of spring, which were hiding in the forests, was the beginning of the game of hide and seek. And despite the fact that a lot of time has passed since the appearance of the game, in some countries, even in our time, the one who hides sometimes imitates the cry of a bird. It is interesting that almost all children's games did not begin as games, but from some historical event or from a legend that people believed in. Sometimes some joyful events served as the beginning for them, sometimes sad ones. "London Bridge is falling" is a game that came into being under very serious circumstances. It doesn't even have anything to do with London! It refers to those times when people believed that after death people had to cross some kind of bridge. Some got on the golden bridge to heaven, while others had to go on the old, rickety bridge to meet the devil. This game is played all over the world, each country has its own name!
