An island or isle is any piece of sub-continental land, surrounded by water. Small islands such as emergent land features on atolls can be called islets, cays or keys. An island in a river or a lake island may be called an eyot or ait, a small island off the coast may be called a holm. A grouping of geographically or geologically related islands is called an archipelago, such as the Philippines. An island may be described despite the presence of an artificial land bridge; some places may retain "island" in their names for historical reasons after being connected to a larger landmass by a land bridge or landfill, such as Coney Island and Coronado Island, though these are speaking, tied islands. Conversely, when a piece of land is separated from the mainland by a man-made canal, for example the Peloponnese by the Corinth Canal or Marble Hill in northern Manhattan during the time between the building of the United States Ship Canal and the filling-in of the Harlem River which surrounded the area, it is not considered an island.
There are two main types of islands in the sea: oceanic. There are artificial islands; the word island derives from Middle English iland, from Old English igland. However, the spelling of the word was modified in the 15th century because of a false etymology caused by an incorrect association with the etymologically unrelated Old French loanword isle, which itself comes from the Latin word insula. Old English ieg is a cognate of Swedish ö and German Aue, related to Latin aqua. Greenland is the world's largest island, with an area of over 2.1 million km2, while Australia, the world's smallest continent, has an area of 7.6 million km2, but there is no standard of size that distinguishes islands from continents, or from islets. There is a difference between continents in terms of geology. Continents are the largest landmass of a particular continental plate. By contrast, islands are either extensions of the oceanic crust, or belong to a continental plate containing a larger landmass. Continental islands are bodies of land.
Examples are Borneo, Sumatra, Sakhalin and Hainan off Asia. A special type of continental island is the microcontinental island, created when a continent is rifted. Examples are Madagascar and Socotra off Africa, New Caledonia, New Zealand, some of the Seychelles. Another subtype is an island or bar formed by deposition of tiny rocks where water current loses some of its carrying capacity; this includes: barrier islands, which are accumulations of sand deposited by sea currents on the continental shelves fluvial or alluvial islands formed in river deltas or midstream within large rivers. While some are transitory and may disappear if the volume or speed of the current changes, others are stable and long-lived. Islets are small islands. Oceanic islands are islands; the vast majority are volcanic in origin, such as Saint Helena in the South Atlantic Ocean. The few oceanic islands that are not volcanic are tectonic in origin and arise where plate movements have lifted up the ocean floor above the surface.
Examples are Saint Paul Rocks in the Atlantic Ocean and Macquarie Island in the Pacific. One type of volcanic oceanic island is found in a volcanic island arc; these islands arise from volcanoes. Examples are the Aleutian Islands, the Mariana Islands, most of Tonga in the Pacific Ocean; the only examples in the Atlantic Ocean are some of the Lesser Antilles and the South Sandwich Islands. Another type of volcanic oceanic island occurs. There are two examples: Iceland, the world's second largest volcanic island, Jan Mayen. Both are in the Atlantic. A third type of volcanic oceanic island is formed over volcanic hotspots. A hotspot is more or less stationary relative to the moving tectonic plate above it, so a chain of islands results as the plate drifts. Over long periods of time, this type of island is "drowned" by isostatic adjustment and eroded, becoming a seamount. Plate movement across a hot-spot produces a line of islands oriented in the direction of the plate movement. An example is the Hawaiian Islands, from Hawaii to Kure, which continue beneath the sea surface in a more northerly direction as the Emperor Seamounts.
Another chain with similar orientation is the Tuamotu Archipelago. The southernmost chain is the Austral Islands, with its northerly trending part the atolls in the nation of Tuvalu. Tristan da Cunha is an example of a hotspot volcano in the Atlantic Ocean. Another hotspot in the Atlantic is the island of Surtsey, formed in 1963. An atoll is an island formed from a coral reef that has grown on an eroded and submerged volcanic island; the reef forms a new island. Atolls are ring-shaped with a central lagoon. Examples are the Line Islands
Niagara Falls is the collective name for three waterfalls that straddle the international border between the Canadian province of Ontario and the US state of New York. They form the southern end of the Niagara Gorge. From largest to smallest, the three waterfalls are the Horseshoe Falls, the American Falls and the Bridal Veil Falls; the Horseshoe Falls lie on the border of the United States and Canada while the American Falls lie on the United States' side, separated by Goat Island. The smaller Bridal Veil Falls are on the United States' side, separated from the American Falls by Luna Island. Located on the Niagara River, which drains Lake Erie into Lake Ontario, the combined falls form the highest flow rate of any waterfall in North America that has a vertical drop of more than 50 metres. During peak daytime tourist hours, more than 168,000 m3 of water goes over the crest of the falls every minute. Horseshoe Falls is the most powerful waterfall in North America; the falls are 27 kilometres north-northwest of Buffalo, New York, 121 kilometres south-southeast of Toronto, between the twin cities of Niagara Falls and Niagara Falls, New York.
Niagara Falls was formed when glaciers receded at the end of the Wisconsin glaciation, water from the newly formed Great Lakes carved a path through the Niagara Escarpment en route to the Atlantic Ocean. Niagara Falls is famed both as a valuable source of hydroelectric power. Balancing recreational and industrial uses has been a challenge for the stewards of the falls since the 19th century; the Horseshoe Falls drop about 57 metres, while the height of the American Falls varies between 21 and 30 metres because of the presence of giant boulders at its base. The larger Horseshoe Falls are about 790 metres wide; the distance between the American extremity of the Niagara Falls and the Canadian extremity is 3,409 feet. The peak flow over Horseshoe Falls was recorded at 6,400 cubic metres per second; the average annual flow rate is 2,400 cubic metres per second. Since the flow is a direct function of the Lake Erie water elevation, it peaks in late spring or early summer. During the summer months, at least 2,800 cubic metres per second of water traverses the falls, some 90% of which goes over the Horseshoe Falls, while the balance is diverted to hydroelectric facilities.
This is accomplished by employing a weir – the International Control Dam – with movable gates upstream from the Horseshoe Falls. The falls' flow is further halved at night, during the low tourist season in the winter, remains a minimum of 1,400 cubic metres per second. Water diversion is regulated by the 1950 Niagara Treaty and is administered by the International Niagara Board of Control; the verdant green colour of the water flowing over the Niagara Falls is a byproduct of the estimated 60 tonnes/minute of dissolved salts and "rock flour" generated by the erosive force of the Niagara River itself. The features that became Niagara Falls were created by the Wisconsin glaciation about 10,000 years ago; the same forces created the North American Great Lakes and the Niagara River. All were dug by a continental ice sheet that drove through the area, deepening some river channels to form lakes, damming others with debris. Scientists argue there is an old valley, St David's Buried Gorge, buried by glacial drift, at the approximate location of the present Welland Canal.
When the ice melted, the upper Great Lakes emptied into the Niagara River, which followed the rearranged topography across the Niagara Escarpment. In time, the river cut a gorge through cuesta; because of the interactions of three major rock formations, the rocky bed did not erode evenly. The top rock formation was composed of erosion-resistant Lockport dolostone; that hard layer of stone eroded more than the underlying materials. The aerial photo on the right shows the hard caprock, the Lockport Formation, which underlies the rapids above the falls, the upper third of the high gorge wall. Below the hard-rock formation, comprising about two-thirds of the cliff, lay the weaker, sloping Rochester Formation; this formation was composed of shale, though it has some thin limestone layers. It contains ancient fossils. In time, the river eroded the soft layer that supported the hard layers, undercutting the hard caprock, which gave way in great chunks; this process repeated countless times carving out the falls.
Submerged in the river in the lower valley, hidden from view, is the Queenston Formation, composed of shales and fine sandstones. All three formations were laid down in an ancient sea, their differences of character deriving from changing conditions within that sea. About 10,900 years ago, the Niagara Falls was between present-day Queenston and Lewiston, New York, but erosion of their crest has caused the waterfalls to retreat 6.8 miles southward. The Horseshoe Falls, which are about 2,600 feet wide, have changed their shape through the process of erosion. Just upstream from the falls' current location, Goat Island splits the course of the Niagara River, resulting in the separation of the Canadian Horseshoe Falls to the west from the American and Bridal Veil Falls to the east. Engineering has slowed recession; the current rate of erosion is appr
The Odawa, said to mean "traders", are an Indigenous American ethnic group who inhabit land in the northern United States and southern Canada. They have long had territory that crosses the current border between the two countries, they are federally recognized as Native American tribes in the United States and have numerous recognized First Nations bands in Canada, they are one of the Anishinaabeg, related to but distinct from the Potawatomi peoples. After migrating from the East Coast in ancient times, they settled on Manitoulin Island, near the northern shores of Lake Huron, the Bruce Peninsula in the present-day province of Ontario, Canada, they considered this their original homeland. After the 17th century, they settled along the Ottawa River, in the states of Michigan and Wisconsin, as well as through the Midwest south of the Great Lakes in the latter country. In the 21st century, there are 15,000 Odawa living in Ontario, Michigan and Oklahoma; the Ottawa dialect is part of the Algonquian language family.
This large family has numerous smaller tribal groups or “bands,” called “Tribe” in the United States and “First Nation” in Canada. Their language is considered a divergent dialect of Ojibwe, characterized by frequent syncope. Odawaa; the Potawatomi spelling of Odawa and the English derivative "Ottawa" are common. The Anishinaabe word for "Those men who trade, or buy and sell" is Wadaawewinini. Fr. Frederic Baraga, a Catholic missionary in Michigan, transliterated this and recorded it in his A Dictionary of the Otchipwe Language as "Watawawininiwok," noting that it meant "men of the bulrushes", associated with the many bulrushes in the Ottawa River. But, this recorded meaning is more appropriately associated with the Matàwackariniwak, a historical Algonquin band who lived along the Ottawa River; the only American tribe, Odawa are the Little Traverse Bay Band of Odawa Indians, the rest are considered Ottawa. Their neighbors applied the "Trader" name to the Odawa because in early traditional times, during the early European contact period, they were noted as intertribal traders and barterers.
The Odawa were described as having dealt "chiefly in cornmeal, sunflower oil and skins, rugs and mats and medicinal roots and herbs."Like the Ojibwe, the Odawa identify as Nishnaabe, meaning "original people". The Odawa name in its English transcription is the source of the place names of Ottawa and the Ottawa River; the Odawa home territory at the time of early European contact, but not their trading zone, was well to the west of the city and river named after them. The tribe is the namesake for Tawas City and Tawas Point, which reflect the syncope-form of their name. Ottawa, Ohio is the county seat of Putnam County, developed at the site of the last Ottawa reservation in Ohio; the Odawa dialect is considered one of several divergent dialects of the Ojibwe language group, noted for its frequent syncope. In the Odawa language, the general language group is known as Nishnabemwin, while the Odawa language is called Daawaamwin. Of the estimated 5,000 ethnic Odawa and additional 10,000 people with some Odawa ancestry, in the early 21st century an estimated 500 people in Ontario and Michigan speak this language.
The Ottawa Tribe of Oklahoma has three fluent speakers. According to Anishinaabeg tradition, from recordings in Wiigwaasabak, the Odawa people came from the eastern areas of North America, or Turtle Island, from along the East Coast. Directed by the miigis beings, the Anishinaabe peoples moved inland along the Saint Lawrence River. At the "Third Stopping Place" near what is now Detroit, the southern group of Anishinaabeg divided into three groups, the Ojibwe and Potawatomi. There is archaeological evidence that the Saugeen Complex people, a Hopewell-influenced group who were located on the Bruce Peninsula during the Middle Woodland period, may have evolved into the Odawa people; the Hopewell tradition was a extended trading network operating from about 200BCE to 500 CE. Some of these peoples constructed earthwork mounds for burials, a practice that ended about 250 CE; the Saugeen mounds have not been excavated. The Odawa, together with the Ojibwe and Potawatomi, were part of a long-term tribal alliance called the Council of Three Fires, which fought the Iroquois Confederacy and the Dakota people.
In 1615 French explorer Samuel de Champlain met 300 men of a nation which, he said, "we call les cheueux releuez" near the French River mouth. Of these, he said: "Their arms consisted only of a bow and arrows, a buckler of boiled leather and the club, they wore no breech clouts, their bodies were tattooed in many fashions and designs, their faces painted and their noses pierced." In 1616, Champlain left the Huron villages and visited the "Cheueux releuez," who lived westward from the lands of the Huron Confederacy. The Jesuit Relations of 1667 report three tribes living in the same town: the Odawa, the Kiskakon Odawa, the Sinago Odawa. All three tribes spoke the same language. Due to the extensive trade network maintained by the Odawa, many of the North American interior nations became known by names which their trading partners used for them, rather than by the nations’ own names. For example, these exonyms include Winnebago for t
Southern Ontario is a primary region of the province of Ontario, the other primary region being Northern Ontario. It is the most densely southernmost region in Canada; the exact northern boundary of Southern Ontario is disputed. It covers between 14 and 15% of the province, depending on the inclusion of the Parry Sound and Muskoka districts which lie in the transitional area between northern and southern forest regions. With more than 12.7 million people, the region is home to one-third of Canada's population of 35.1 million. Southern Ontario differs from Northern Ontario, in that it has a much larger population density, a different climate, a different culture than its northern counterpart, it is broken into smaller subregions, including Central Ontario, Georgian Triangle, Southwestern Ontario, the Golden Horseshoe, Eastern Ontario. The core area of Southern Ontario is part of the Quebec City–Windsor Corridor, which extends northeast into southern Quebec; the transitional northern area of this primary region extends north to the Mattawa River and occupies part of the Grenville Geological Province of the Canadian Shield which extends northeast into southern Quebec.
Southern Ontario can be distinguished from Northern Ontario because it is far more densely populated and contains the majority of the province's cities, major roads, institutions. Northern Ontario, in contrast, contains remote wilderness. Although it has no saltwater coastline, the region has an abundance of freshwater coastlines on three Great Lakes, as well as smaller lakes such as Lake Simcoe and Lake St. Clair, it is a major vineyard producer of Canadian wines. While Southern Ontario has been a part of the province of Ontario since its establishment at Confederation in 1867 forming the colony of Upper Canada, a large portion of Northern Ontario did not become part of Ontario until 1912. Territorial Southern Ontario was explored and colonized by the French in the 17th century, who forged relations with the Wyandot Huron people, based around the Georgian Bay/Lake Simcoe area. Other Iroquoian speaking people to the south were the Petun and Neutral Nation, further northeast, Algonquins inhabited the upper Ottawa River/Madawaska Valley areas and the Mississaugas moved south from northern Lake Huron, settling lands in both the Kawartha region and just west of Toronto.
Following the Seven Years' War, the British wrested control of Southern Ontario, greater colonization efforts were spurred on by the arrival of United Empire Loyalists brought on by the American Revolution. Southern Ontario was where a large portion of the battles took place during the War of 1812, was a major destination for escaping slaves using the underground railroad. Following the enactment of Prohibition in the United States in 1919, Southern Ontario became a hotbed of smuggling alcohol across the border. Southern Ontario is home to over 94%, or 12.1 million, of Ontario's total population of 12.9 million people, compared to 750,000 in Northern Ontario. This is due to many factors, including the more arable land in the south, its more moderate climate, well-used transportation routes, proximity to populated areas of the Northeastern and Midwestern United States, as well as a long history of early European settlers and colonialism. For thousands of years, Ontario has been home to indigenous aboriginal communities, with numerous nations with differing languages at the time of European contact.
Over 200,000 aboriginal Canadians live in Southern Ontario today. Southern Ontario was colonized by the British. After the area began to be developed for European settlement after the American Revolutionary War, other European immigrants arrived as well, with increased immigration in the late 19th and early 20th centuries. Since the late 20th century, many immigrants have come from other parts of the world; the region is one of the top destinations for immigrants worldwide the Greater Toronto Area. The area has a large manufacturing sector. Since the mid-2000s, Ontario has produced more vehicles per year than the state of Michigan. In a cross-border definition, a swath of Southern Ontario could be considered a part of the Rust Belt. Factory closings because of industry restructuring, globalization have for the past few decades taken their toll; this is most evident in the region's southern tier cities which have large automobile or associated industrial bases, such as Windsor, London, St. Thomas and St. Catharines.
Still affected by these factors but to a lesser extent is Hamilton, the centre of steel production, Sarnia, the centre of petrochemical production. The province's two largest cities and Ottawa, have moved to a service and knowledge economy, although Toronto still has a strong industrial presence spread over wide areas along its rail and highway corridors as well as a container port linking it to the St. Lawrence Seaway. Toronto, the largest city of the province, is the site of all of the major Canadian banks and its heart has the country's financial sector, including the Toronto Stock Exchange. Ottawa, the national capital, has an economy, dependent on the public sector, in addition to having a strong technology sector; some parts of Southern Ontario are heavil
Billings is a township in the Canadian province of Ontario, as well as the name of a community within that township. Located in the Manitoulin District, the township had a population of 506 in the Canada 2011 Census; the primary community in the township is Kagawong. There are three smaller communities: Billings, Bowser's Corner, Pleasant Valley. Kagawong's harbour is located on Mudge Bay and is home to the Kagawong Lighthouse, in continuous service since 1888; the name Kagawong means "where mists rise from falling waters" in the Ojibwe language, a reference to the nearby Bridal Veil Falls on the Kagawong River. Kagawong is home to numerous tourist attractions; the most popular being the famed Bridal Veil Falls. The legend is; the falls begin at the end of the upper Kagawong river, flow past a series of small, cascading waterfalls down a winding trail towards Mudge Bay. The trails are spotted with art pieces and picnic tables. In addition to the falls, Kagawong is home to a Transportation and Communication Museum, Art Gallery, Anglican Church, several sandy beaches, many camping and cottage rental opportunities.
Kagawong is the nearest port of call to the islands of the North Channel, being directly south of Clapperton Island and the Benjamin Islands. List of townships in Ontario Township of Billings
Lake Manitou is the largest lake on Manitoulin Island in Ontario, Canada. It is the largest lake on a lake island in the world. Since Manitoulin Island itself is in Lake Huron, one of the Great Lakes, Manitou qualifies as the largest "lake in a lake". Lake Manitou has an area of about 104 square kilometres, it is drained by the Manitou River. There are a number of small islands in Lake Manitou, making them islands in a lake on an island in another lake. List of lakes in Ontario Geographic data related to Lake Manitou at OpenStreetMap
