Oak vs Abu Dhabi

Informations

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.

Abu Dhabi (UK:, US:; Arabic: أَبُو ظَبْيٍ‎ Abū Ẓaby Arabic pronunciation: [ɐˈbuˈðˤɑbi]) is the capital and the second-most populous city of the United Arab Emirates (later Dubai). The city of Abu Dhabi is located on an island in the Persian Gulf, off the Central West Coast. The Majority of the city and the Emirate live on the mainland connected to the rest of the country. As of 2020, Abu Dhabi's urban area had an estimated population of 1.48 million, out of 2.9 million in the emirate of Abu Dhabi, as of 2016. Abu Dhabi homes local and national government offices and is the home of the United Arab Emirates Government and the Supreme Petroleum Council.

The city is home to the President of the UAE, who's a member of the Al Nahyan family. Abu Dhabi's rapid development and urbanization, coupled with the gigantic oil and gas reserves and production and relatively high average income, have transformed it into a big, developed metropolis. It's the nation's center of politics and business, and a significant culture and commerce center. Abu Dhabi accounts for approximately two-thirds of the approximately $400 billion UAE economy.
