Sarnia vs Tabriz

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.

The valley opens up into a plain that gently slopes down to the eastern shores of Lake Urmia, 60 kilometres (37 miles) to the west. With cold winters and temperate summers, Tabriz is considered a summer resort. It was named World Carpet Weaving City by the World Crafts Council in October 2015 and Exemplary Tourist City of 2018 by the Organisation of Islamic Cooperation.With a population of over 1.7 million (2016), Tabriz is the largest economic hub and metropolitan area in Northwest Iran.

From the early modern era, Tabriz was pivotal in the development, movement and economy of its three neighboring regions; namely the Caucasus, Eastern Anatolia and Central Iran. In modern era city played a vital role in the history of Iran. As the country's closest hub to Europe, many aspects of early modernisation in Iran began in Tabriz.

Until 1925, the city was the traditional residence of the Qajar crown princes.
