Sarnia vs Bolton

Informations

Sarnia is a city in Southwestern Ontario, Canada, with a 2016 population of 71,594. It is the largest city on Lake Huron and in Lambton County. Sarnia is located on the eastern bank of the junction between the Upper and Lower Great Lakes where Lake Huron flows into the St. Clair River, which forms the Canada–United States border, directly across from Port Huron, Michigan. The site's natural harbour first attracted the French explorer La Salle. He named the site "The Rapids" on 23 August 1679, when he had horses and men pull his 45-ton barque Le Griffon north against the nearly four-knot current of the St. Clair River.This was the first time that a vessel other than a canoe or other oar-powered vessel had sailed into Lake Huron, and La Salle's voyage was germinal in the development of commercial shipping on the Great Lakes. Located in the natural harbour, the Sarnia port remains an important centre for lake freighters and oceangoing ships carrying cargoes of grain and petroleum products. The natural port and the salt caverns that exist in the surrounding areas, together with the oil discovered in nearby Oil Springs in 1858, led to the dramatic growth of the petroleum industry in this area.

Because Oil Springs was the first place in Canada and North America to drill commercially for oil, the knowledge that was acquired there resulted in oil drillers from Sarnia travelling the world teaching other enterprises and nations how to drill for oil.The complex of refining and chemical companies is called Chemical Valley and located south of downtown Sarnia. In 2011 the city had the highest level of particulates air pollution of any Canadian city, but it has since dropped to rank 30th in this hazard. About 60 percent of the particulate matter comes from industries and polluters in the neighbouring United States.Lake Huron is cooler than the air in summer and warmer than the air in winter; therefore, it moderates Sarnia's humid continental climate, making temperature extremes of hot and cold less evident. In the winter, Sarnia occasionally experiences lake-effect snow from Arctic air blowing across the warmer waters of Lake Huron and condensing to form snow squalls over land.

Bolton ( (listen), locally ) is a large town in Greater Manchester in North West England, historically and traditionally a part of Lancashire. A former mill town, Bolton has been a production centre for textiles since Flemish weavers settled in the area in the 14th century, introducing a wool and cotton-weaving tradition. The urbanisation and development of the town largely coincided with the introduction of textile manufacture during the Industrial Revolution. Bolton was a 19th-century boomtown and, at its zenith in 1929, its 216 cotton mills and 26 bleaching and dyeing works made it one of the largest and most productive centres of cotton spinning in the world. The British cotton industry declined sharply after the First World War and, by the 1980s, cotton manufacture had virtually ceased in Bolton. Close to the West Pennine Moors, Bolton is 10 miles (16 km) north-west of Manchester. It is surrounded by several smaller towns and villages that together form the Metropolitan Borough of Bolton, of which Bolton is the administrative centre.

The town of Bolton has a population of 139,403, whilst the wider metropolitan borough has a population of 262,400. Bolton originated as a small settlement in the moorland known as Bolton le Moors. In the English Civil War, the town was a Parliamentarian outpost in a staunchly Royalist region and, as a result, was stormed by 3,000 Royalist troops led by Prince Rupert of the Rhine in 1644. In what became known as the Bolton Massacre, 1,600 residents were killed and 700 were taken prisoner. Bolton Wanderers football club play home games at the University of Bolton Stadium and the WBA World light-welterweight champion Amir Khan was born in the town. Cultural interests include the Octagon Theatre and the Bolton Museum and Art Gallery, as well as one of the earliest public libraries established after the Public Libraries Act 1850.
