Köppen climate classificationThe Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, German climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification.
WallachiaWallachia or Walachia (wɒ'leɪkiə; Țara Românească, ˈt͡sara romɨˈne̯askə; archaic: Țeara Rumânească, Romanian Cyrillic alphabet: Цѣра Рꙋмѫнѣскъ) is a historical and geographical region of Romania. It is situated north of the Lower Danube and south of the Southern Carpathians. Wallachia is traditionally divided into two sections, Muntenia (Greater Wallachia) and Oltenia (Lesser Wallachia). Dobruja could sometimes be considered a third section due to its proximity and brief rule over it.
Oil refineryAn oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into useful products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha. Petrochemical feedstock like ethylene and propylene can also be produced directly by cracking crude oil without the need of using refined products of crude oil such as naphtha. The crude oil feedstock has typically been processed by an oil production plant.
BucharestBucharest (UKˌbuːkəˈrɛst , USˈbuːkərɛst ; București bukuˈreʃtj) is the capital and largest city of Romania. It is described as the cultural, financial, entertainment, and media center in the country with a significant influence in Eastern and Southeastern Europe as well. In geopolitical regards, Bucharest has been and still is an important capital of a state situated in Central and Eastern Europe, where noteworthy summits had taken place (for example the 2008 Bucharest summit).
PetrochemicalPetrochemicals (sometimes abbreviated as petchems) are the chemical products obtained from petroleum by refining. Some chemical compounds made from petroleum are also obtained from other fossil fuels, such as coal or natural gas, or renewable sources such as maize, palm fruit or sugar cane. The two most common petrochemical classes are olefins (including ethylene and propylene) and aromatics (including benzene, toluene and xylene isomers). Oil refineries produce olefins and aromatics by fluid catalytic cracking of petroleum fractions.
MoldaviaMoldavia (Moldova, molˈdova or Țara Moldovei, literally "The Country of Moldavia"; in Romanian Cyrillic: Молдова or Цара Мѡлдовєй; Землѧ Молдавскаѧ; Ἡγεμονία τῆς Μολδαβίας) is a historical region and former principality in Central and Eastern Europe, corresponding to the territory between the Eastern Carpathians and the Dniester River. An initially independent and later autonomous state, it existed from the 14th century to 1859, when it united with Wallachia (Țara Românească) as the basis of the modern Romanian state; at various times, Moldavia included the regions of Bessarabia (with the Budjak), all of Bukovina and Hertsa.
