Trafalgar Moraine
The Trafalgar Moraine is a geological landform straddling Oakville and Milton in Ontario, Canada. A small portion of the moraine extends into Burlington at Milton's southern border. It is a subtler topological feature than the better-known Oak Ridges Moraine, primarily because it was formed as an end moraine at the terminus of a glacial ice sheet, instead of between two retreating ice lobes (known as ''interlobate''). The ice sheet pushed material to form the ridge, which is composed of ''Halton Till'' sediment, rich in silt and clay. By contrast, the Oak Ridges Moraine is primarily sand and gravel. The ridge was probably formed during a pause in the retreat of the ice sheet. The moraine covers an area of 892.5 hectares of primarily private land, though a small portion is public. Geology The Trafalgar Moraine is formed primarily of silty, clay-rich sand, and underpinned by shale bedrock, all of which hinder water absorption. Nonetheless, a few areas serve as surface water reservoir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

Ontario
Ontario ( ; ) is one of the thirteen provinces and territories of Canada.Ontario is located in the geographic eastern half of Canada, but it has historically and politically been considered to be part of Central Canada. Located in Central Canada, it is Canada's most populous province, with 38.3 percent of the country's population, and is the second-largest province by total area (after Quebec). Ontario is Canada's fourth-largest jurisdiction in total area when the territories of the Northwest Territories and Nunavut are included. It is home to the nation's capital city, Ottawa, and the nation's most populous city, Toronto, which is Ontario's provincial capital. Ontario is bordered by the province of Manitoba to the west, Hudson Bay and James Bay to the north, and Quebec to the east and northeast, and to the south by the U.S. states of (from west to east) Minnesota, Michigan, Ohio, Pennsylvania, and New York. Almost all of Ontario's border with the United States f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...

Burlington, Ontario
Burlington is a city in the Regional Municipality of Halton at the northwestern end of Lake Ontario in Ontario, Canada. Along with Milton to the north, it forms the western end of the Greater Toronto Area and is also part of the Hamilton metropolitan census area. History Before the 19th century, the area between the provincial capital of York and the township of West Flamborough was home to the Mississauga nation. In 1792, John Graves Simcoe, the first lieutenant governor of Upper Canada, named the western end of Lake Ontario "Burlington Bay" after the town of Bridlington in the East Riding of Yorkshire, England. The British purchased the land on which Burlington now stands from the Mississaugas in Upper Canada Treaties 3 (1792), 8 (1797), 14 (1806), and 19 (1818). Treaty 8 concerned the purchase of the Brant Tract, on Burlington Bay which the British granted to Mohawk chief Joseph Brant for his service in the American Revolutionary War. Joseph Brant and his household se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oak Ridges Moraine
The Oak Ridges Moraine is an ecologically important geological landform in the Mixedwood Plains of south-central Ontario, Canada. The moraine covers a geographic area of between Caledon and Rice Lake, near Peterborough. One of the most significant landforms in southern Ontario, the moraine gets its name from the rolling hills and river valleys extending from the Niagara Escarpment east to Rice Lake. It was formed 12,000 years ago by advancing and retreating glaciers (''see'' geological origins, below). The moraine is a contested site in Ontario, since it stands in the path of major urban development (''see'' political action). Physiography The Oak Ridges Moraine is a pair of large ridges composed of four elevated wedges. It is bounded to the west by the Niagara Escarpment, a cuesta which was critical to the formation of the moraine, and to the east by the Trent River and Rice Lake. The four wedges (''Albion'', ''Uxbridge'', ''Pontypool'' and ''Rice Lake'' from west to east) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terminal Moraine
A terminal moraine, also called end moraine, is a type of moraine that forms at the terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by the front edge of the ice, is driven no further and instead is deposited in an unsorted pile of sediment. Because the glacier acts very much like a conveyor belt, the longer it stays in one place, the greater the amount of material that will be deposited. The moraine is left as the marking point of the terminal extent of the ice. Formation As a glacier moves along its path, the surrounding area is continuously eroding. Loose rock and pieces of bedrock are constantly being picked up and transported with the glacier. Fine sediment and particles are also incorporated into the glacial ice. The accumulation of these rocks and sediment together form what is called glacial till when deposited. Push moraines are formed when a glacier retreats from a previou ...

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 Ontario, Lak ...

Streetsville, Ontario
Streetsville (pop. 47,327) is a neighbourhood located in the northwestern corner of the city of Mississauga, Ontario, Canada, on the Credit River. Although Streetsville occupies the west and east banks of the river, the majority is located on the west bank of the river. A town prior to the 1974 amalgamations that formed the City of Mississauga, it seeks to keep a "small town" charm by retaining a variety of historical buildings and streetscapes. As part of this attempt to maintain a separate identity from the larger city, the names of two main Mississauga streets, as they pass through Streetsville, retain the names they had when Streetsville was an independent village: List of roads in Mississauga#Mississauga Road, Mississauga Road and Bristol Road, which remain as Queen Street and Main Street respectively. Other main thoroughfares that pass through or near Streetsville include List of roads in Mississauga#Britannia Road, Britannia Road, List of roads in Mississauga#Creditview Roa ...
