Macedonia is a geographical and historical region of the Balkan peninsula in southeastern Europe.
 Its boundaries have changed considerably over time, however it came to be defined as the modern geographical region by the mid 19th century.
 Nowadays the region is considered to include parts of six Balkan countries: Greece, the Republic of Macedonia, Bulgaria, Albania, Serbia and Kosovo.
 It covers approximately 67000 km2 and has a population of 4.76 million.
Upper Silesia (Polish: "Górny Śląsk" ; Silesian: "Gůrny Ślůnsk"; Czech: "Horní Slezsko" ; German: "Oberschlesien" ; Silesian German: "Oberschläsing"; Latin: "Silesia Superior" ) is the southeastern part of the historical and geographical region of Silesia, located mostly in Poland, with small parts in the Czech Republic.
The Lesser Poland Gorge of the Vistula (Polish: "Małopolski Przełom Wisły") is a geographical region located in central-eastern Poland, which administratively belongs to three Polish voivodeships – Lublin, Masovian, and Świętokrzyskie.
 The Gorge is for the most part made by the valley of the Vistula, with two Polish uplands on both sides of the river – Lesser Poland (or Małopolska) Upland to the west, and Lublin Upland to the east.
 The gorge is about 70 kilometers long, extending from the town of Zawichost in the south, to Puławy in the north.
 It is considerably narrow, only up to 3 kilometers wide.
 In some places, the banks of the Vistula valley are very steep, up to 70 meters above the water level.
The Mazovian Lowland (Polish: "Nizina Mazowiecka" ), also known as the Masovian Plain, is the largest geographical region in central Poland, roughly covering the historical region of Masovia.
 Sometimes it is also categorized as including Mazovian-Podlasian Lowlands which together form part of the greater East European Plain.
Buława , German Buhlau, is a village in the administrative district of Gmina Strzeleczki (Gemeinde Klein Strehlitz), within Krapkowice County, Opole Voivodeship, in the south-western region of Upper Silesia in Poland.

Cameroon has a rich and diverse culture made up of a mix of about 250 indigenous populations and just as many languages and customs.
 The country is nicknamed "Little Africa" as geographically, Cameroon consists of coastline, mountains, grass plains, forest, rainforest and desert, all of the geographical regions in Africa in one country.
 This also contributes to its cultural diversity as ways of life and traditional food dishes and traditions vary from geographical region to geographical region.
The Urals (Russian: Ура́л ) are a geographical region located around the Ural Mountains, between the East European and West Siberian plains.
 It extends approximately from north to south, from the Arctic Ocean to the bend of Ural River near Orsk city.
 The boundary between Europe and Asia runs along the eastern side of the Ural Mountains.
 Ural mostly lies within Russia but also includes a part of northwestern Kazakhstan.
 This is a historical, not an official entity, with the boundaries overlapping its western Volga and eastern Siberia neighbor regions.
 At points in time, parts of the Urals were considered a gateway to Siberia, if not Siberia itself, or were combined with the Volga administrative divisions.
 At present time, there are two official namesake entities, the Ural Federal District and the Ural economic region.
 While the latter follows the historical boundaries, the former is a political product; the District omits Western Urals and includes Western Siberia instead.
The Texas Hill Country is a geographical region located in the Edwards Plateau at the crossroads of West Texas, Central Texas, and South Texas.
 Given its geographical location, terrain features, and native vegetation, the Hill Country could be considered the beginning or end of the American Southwest (depending on which direction one is travelling).
 The region is notable for its karst topography and tall rugged hills of limestone or granite.
 Many of the hills rise to a height of 400-500 feet above the surrounding plains and valleys, with Packsaddle Mountain rising to a height of 800 feet above the Llano River in Kingsland.
 The Hill Country also includes the Llano Uplift and the second-largest granite dome in the United States, Enchanted Rock.
 The terrain throughout the region is punctuated by a thin layer of topsoil and a large number of exposed rocks and boulders, making the region very dry and prone to flash flooding.
 Native vegetation in the region includes various yucca, prickly pear cactus, desert spoon, and wildflowers in the Llano Uplift.
 The predominant trees in the region are ashe juniper and Texas live oak.
