Answer:
Dams help in preventing floods. They catch extra water so that it doesn't run wild downstream. Dam operators can let water out through the dam when needed. The first upstream flood control dam was built in 1948, Cloud Creek Dam in Oklahoma.
People build reservoirs because the amount of water in a river varies over time. During very rainy times or when mountain snow is melting, the water in a river rises and sometimes overflows its banks. By limiting the amount of water allowed to continue downriver, reservoirs help control flooding.
Explanation:
Effect: The war changed economic, political, governmental, and social relations between Britain, France, and Spain; their colonies and colonists; and the American Indians that inhabited the territories they claimed. France and Britain both suffered financially because of the war, with significant long-term consequences.
Causes: In the early 1750s, French expansion into the Ohio River valley repeatedly brought France into armed conflict with the British colonies. In 1756–the first official year of fighting in the Seven Years War–the British suffered a series of defeats against the French and their broad network of Native American alliances.
By means of a complex engineering feat the 1960s the temples were salvaged from the rising waters of the mile river caused by erection of the Aswan high Dam. Colossal statues of Ramses ll seated at the main entrance to the great temple at Abu Simbel.
It is least likely that Japan will be experiencing population growth.
Explanation:
Japan is a country that has a very large population for a country of its size, over 120 million people. Japan though, faces huge demographic problems, which will be more and more serious as the years pass by. The problems now are not that the population is very large, but that the population is aging and will start to experience sharp decrease in the coming decades.
The total fertility rate (TFR) of the country is only 1.27, which is far from enough for simple replacement of the population, as for that a TFR of 2 is needed. Less and less children are born, which in turn provides smaller and smaller population for reproduction with each generation. On the other hand, Japan is a country that has one of the highest life expectancy in the world, and the old population is constantly on the rise.
Such situation brings in lot of economic problems, as very soon the number of old people will equal the number of people of working age, and that is almost impossible to be managed. The Japanese governments have been trying to persuade the young people to form a family and have more children, but the reality is the opposite, as more and more young people decide to be solitary, not form a family, and if they do, they tend to have one child, or maybe two.
