Niagara Falls
Niagara Falls () is a group of three waterfalls at the southern end of Niagara Gorge, spanning the Canada–United States border, border between the Provinces and territories of Canada, province of Ontario in Canada and the U.S. state, state of New York (state), New York in the United States. The largest of the three is Horseshoe Falls, which straddles the Canada–United States border, international border of the two countries. It is also known as the Canadian Falls. The smaller American Falls and Bridal Veil Falls (Niagara Falls), Bridal Veil Falls lie within the United States. Bridal Veil Falls is separated from Horseshoe Falls by Goat Island (New York), Goat Island and from American Falls by Luna Island, with both islands situated in New York. Formed by the Niagara River, which drains Lake Erie into Lake Ontario, the combined falls have the List of waterfalls by flow rate, highest flow rate of any waterfall in North America that has a vertical drop of more than .

American Falls
The American Falls is the second-largest of the three waterfalls that together are known as Niagara Falls on the Niagara River along the Canada–U.S. border. Unlike the much larger Horseshoe Falls, of which approximately 90% is in Ontario, Canada and 10% in the U.S. state of New York, the American Falls is entirely within the United States. Characteristics The falls receive approximately 11% of the flow from Niagara River, with most of the rest going over Horseshoe Falls, from which it is separated by Goat Island. It has a straight line crest width of about . If measured along the jagged lip of the falls, the crest is about long (but see coastline paradox). The torrent of water passing over the crest of the falls is about deep. The height of the American Falls ranges between . This measurement is taken from the top of the Falls to top of the rock pile ( talus). The height of the Falls from the top of the Falls to the river is . Visitors can view the falls from a st ...

Waterfall
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Niagara Falls, New York
Niagara Falls is a city in Niagara County, New York, United States. As of the 2020 census, the city had a total population of 48,671. It is adjacent to the Niagara River, across from the city of Niagara Falls, Ontario, and named after the famed Niagara Falls which they share. The city is within the Buffalo–Niagara Falls metropolitan area and the Western New York region. While the city was formerly occupied by Native Americans, Europeans who migrated to the Niagara Falls in the mid-17th century began to open businesses and develop infrastructure. Later in the 18th and 19th centuries, scientists and businessmen began harnessing the power of the Niagara River for electricity and the city began to attract manufacturers and other businesses drawn by the promise of inexpensive hydroelectric power. After the 1960s, however, the city and region witnessed an economic decline, following an attempt at urban renewal under then Mayor Lackey. Consistent with the rest of the Rust Belt as ...

Niagara River
The Niagara River () is a river that flows north from Lake Erie to Lake Ontario. It forms part of the border between the province of Ontario in Canada (on the west) and the state of New York in the United States (on the east). There are differing theories as to the origin of the river's name. According to Iroquoian scholar Bruce Trigger, ''Niagara'' is derived from the name given to a branch of the locally residing native Neutral Confederacy, who are described as being called the ''Niagagarega'' people on several late-17th-century French maps of the area. According to George R. Stewart, it comes from the name of an Iroquois town called ''Ongniaahra'', meaning "point of land cut in two". The river, which is occasionally described as a strait, is about long and includes Niagara Falls in its course. The falls have moved approximately upstream from the Niagara Escarpment in the last 12,000 years, resulting in a gorge below the falls. Today, the diversion of the river for ele ...

Twin Cities
Twin cities are a special case of two neighboring cities or urban centres that grow into a single conurbation – or narrowly separated urban areas – over time. There are no formal criteria, but twin cities are generally comparable in status and size, though not necessarily equal; a city and a substantially smaller suburb would not typically qualify, even if they were once separate. Tri-cities and quad cities are similar phenomena involving three or four municipalities. A common – but not universal – scenario is two cities that developed concurrently on opposite sides of a river. For example, Minneapolis and Saint Paul in Minnesota – one of the most widely known "Twin Cities" – were founded several miles apart on opposite sides of the Mississippi River, and competed for prominence as they grew. In some cases, twin cities are separated by a state border, such as Albury (New South Wales) and Wodonga ( Victoria) in Australia, on opposite sides of the Murray River ...

Rock Flour
Rock flour, or glacial flour, consists of fine-grained, silt-sized particles of rock, generated by mechanical grinding of bedrock by glacial erosion or by artificial grinding to a similar size. Because the material is very small, it becomes suspended in meltwater making the water appear cloudy, which is sometimes known as glacial milk. When the sediments enter a river, they turn the river's colour grey, light brown, iridescent blue-green, or milky white. If the river flows into a glacial lake, the lake may appear turquoise in colour as a result. When flows of the flour are extensive, a distinct layer of a different colour flows into the lake and begins to dissipate and settle as the flow extends from the increase in water flow from the glacier during snow melts and heavy rain periods. Examples of this phenomenon may be seen at Lake Pukaki and Lake Tekapo in New Zealand, Lake Louise, Moraine Lake, Emerald Lake, and Peyto Lake in Canada, Gjende lake in Norway, and several lakes ...

International Control Dam
The International Control Dam, also known as the International Control Structure, operated by Ontario Power Generation, is a weir that controls the water diversions from the Niagara River and dispatches the water between the New York Power Authority and Ontario Power Generation in accordance with the terms of the 1950 Niagara Treaty. It was completed in 1954. To preserve Niagara Falls' natural beauty and to ensure an "unbroken curtain of water" is flowing over the falls, the 1950 treaty was signed by the U.S. and Canada to limit water usage by power plants. The treaty allows higher summertime diversion at night when tourists are fewer and during the winter months when there are even fewer tourists. The treaty states that during daylight time during the tourist season (April 1 to October 31) there must be 100,000 cubic feet per second (2,800 m3/s) of water flowing over the falls, and during the night and off-tourist season there must be 50,000 cubic feet per second (1,400 m3/s) of ...

Weir
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. Etymology There is no single definition as to what constitutes a weir and one English dictionary simply defines a weir as a small dam, likely originating from Middle English ''were'', Old English ''wer'', derivative of root of ''werian,'' meaning "to defend, dam". Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more navigable by boat. In some locations, the terms dam and weir are synonymous, but normally there is a clear distinction made between the structures. Usually, a dam is designed specifically to impound water beh ...

Canadian Horseshoe Falls With City Of Niagara Falls, Ontario In Background
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and ec ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Niagara Escarpment
The Niagara Escarpment is a long escarpment, or cuesta, in Canada and the United States that runs predominantly east–west from New York through Ontario, Michigan, Wisconsin, and into Illinois. The escarpment is most famous as the cliff over which the Niagara River plunges at Niagara Falls, for which it is named. The escarpment is a UNESCO World Biosphere Reserve. The reserve has the oldest forest ecosystem and trees in eastern North America. The escarpment is not a fault line but the result of unequal erosion. It is composed of an outcrop belt of the Lockport Formation of Silurian age, and is similar to the Onondaga Formation, which runs in a parallel outcrop belt just to the south, through western New York and southern Ontario. The escarpment is the most prominent of several escarpments formed in the bedrock of the Great Lakes Basin. From its easternmost point near Watertown, New York, the escarpment shapes in part the individual basins and landforms of Lake Ontar ...

Great Lakes
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the mid-east region of North America that connect to the Atlantic Ocean via the Saint Lawrence River. There are five lakes, which are Superior, Michigan, Huron, Erie, and Ontario and are in general on or near the Canada–United States border. Hydrologically, lakes Michigan and Huron are a single body joined at the Straits of Mackinac. The Great Lakes Waterway enables modern travel and shipping by water among the lakes. The Great Lakes are the largest group of freshwater lakes on Earth by total area and are second-largest by total volume, containing 21% of the world's surface fresh water by volume. The total surface is , and the total volume (measured at the low water datum) is , slightly less than the volume of Lake Baikal (, 22–23% of the world's surface fresh water). Because of their sea-like characteristics, such as rolling waves, sustained wi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
