Kinshasa vs Oak

Informations

Kinshasa (; French: [kinʃasa]; Lingala: Kinsásá), formerly Léopoldville (Dutch: Leopoldstad), is the capital and the largest city of the Democratic Republic of the Congo. The city is situated alongside the Congo River. Once a site of fishing and trading villages, Kinshasa is now a megacity with a population of about 16 million. It faces Brazzaville, the capital of the neighbouring Republic of the Congo, which can be seen in the distance across the wide Congo River, making them the world's second-closest pair of capital cities after Rome and Vatican City. The city of Kinshasa is also one of the DRC's 26 provinces. Because the administrative boundaries of the city-province cover a vast area, over 90 percent of the city-province's land is rural in nature, and the urban area occupies a small but expanding section on the western side.

Kinshasa is Africa's third-largest urban area after Cairo and Lagos. It is also the world's largest Francophone urban area (surpassing Paris in population), with French being the language of government, schools, newspapers, public services, and high-end commerce in the city, while Lingala is used as a lingua franca in the street. Kinshasa hosted the 14th Francophonie Summit in October 2012.Residents of Kinshasa are known as Kinois (in French and sometimes in English) or Kinshasans (English). The indigenous people of the area include the Humbu and Teke.

An oak is a tree or shrub in the genus Quercus (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably Lithocarpus (stone oaks), as well as in those of unrelated species such as Grevillea robusta (silky oaks) and the Casuarinaceae (she-oaks). The genus Quercus is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America contains the largest number of oak species, with approximately 90 occurring in the United States, while Mexico has 160 species of which 109 are endemic. The second greatest center of oak diversity is China, which contains approximately 100 species.

Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. Many deciduous species are marcescent, not dropping dead leaves until spring. In spring, a single oak tree produces both male flowers (in the form of catkins) and small female flowers, meaning that the trees are monoecious. The fruit is a nut called an acorn or oak nut borne in a cup-like structure known as a cupule; each acorn contains one seed (rarely two or three) and takes 6–18 months to mature, depending on their species. The acorns and leaves contain tannic acid, which helps to guard from fungi and insects. The live oaks are distinguished for being evergreen, but are not actually a distinct group and instead are dispersed across the genus.
