Sarnia vs Guatemala City

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.

Guatemala City (Spanish: Ciudad de Guatemala), locally known as Guatemala or Guate, formally Ciudad de Guatemala (art. 231 of the Political Constitution of the Republic of Guatemala), is the capital and largest city of Guatemala, and the most populous metropolitan area in Central America. The city is situated in the south-central portion of the country, nestled in a mountain valley named Valle de la Ermita (English: Hermitage Valley). It is projected that its population is about 1 million. Guatemala City is also the capital of the Municipality of Guatemala and of the Guatemala Department. Guatemala City is the site of the Mayan city of Kaminaljuyu, based around 1500 BC. Following the Spanish conquest, a new city was established, and in 1776 it was made capital of the Kingdom of Guatemala.

In 1821, Guatemala City was the scene of the declaration of independence of Central America from Spain, and it became the capital of the newly established United Provinces of Central America (after the Federal Republic of Central America). In 1847, Guatemala declared itself an independent republic, with Guatemala City as its capital. The town was almost entirely destroyed by the 1917--18 earthquakes. Reconstructions following the earthquakes have resulted in a more modern architectural landscape.Today, Guatemala City is the political, cultural, and economic center of Guatemala. It is served by La Aurora International Airport.
