Context: Kyustendil Province (trl "Oblast Kyustendil") is a province in southwestern Bulgaria, extending over an area of 3084.3 km² (constituting 2.7% of the total territory of the Republic of Bulgaria), and with a population of 163,889. It borders on the provinces of Sofia, Pernik, and Blagoevgrad; to the west, its limits coincide with the state borders between Bulgaria and the Republic of Macedonia, and between Bulgaria and the Republic of Serbia. The administrative center of the Province is Kyustendil., Thunder is the sound caused by lightning. Depending on the distance and nature of the lightning, thunder can range from a sharp, loud crack to a long, low rumble (brontide). The sudden increase in pressure and temperature from lightning produces rapid expansion of the air surrounding and within a bolt of lightning. In turn, this expansion of air creates a sonic shock wave, similar to a sonic boom, which produces the sound of thunder, often referred to as a "clap", "crack", "peal of thunder", or "boom"., A ski is a narrow strip of semi-rigid material worn underfoot to glide over snow. Substantially longer than wide and characteristically employed in pairs, skis are attached to ski boots with ski bindings, with either a free, lockable, or partially secured heel. For climbing slopes, ski skins (originally made of seal fur, but now made of synthetic materials) can be attached at the base of the ski., The Balkan Peninsula, or the Balkans, is a peninsula and a cultural area in Eastern and Southeastern Europe with various and disputed borders. The region takes its name from the Balkan Mountains that stretch from the Serbia-Bulgaria border to the Black Sea., Kyustendil is a town in the far west of Bulgaria, and the capital of the Kyustendil Province.

The total population counts 44,532 people, with a Bulgarian majority and Roma minority. During the Iron Age, a Thracian settlement was located within the town, later known as Roman in the 1st century AD. In the Middle Ages, the town switched hands between the Byzantine Empire, Bulgaria and Serbia, prior to Ottoman annexation in 1395. After centuries of Ottoman rule, the town became part of an independent Bulgarian state in 1878., An ecoregion (ecological region) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than an ecozone. All three of these are either less or greater than an ecosystem. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point)., Musala (from Arabic through Ottoman Turkish: Musalla, "near God" or "place for prayer" is the highest peak in the entire Balkan Peninsula, standing at 2,925 m (9,596 ft).

The city has a population of 1.26 million, while 1.68 million people live in its metropolitan area. The city is located at the foot of Vitosha Mountain in the western part of the country, within less than drive from the Serbian border. Its location in the centre of the Balkan peninsula means that it is the midway between the Black Sea and the Adriatic Sea, whereas the Aegean Sea is the closest to it., A mountain range (also mountain barrier, belt, or system) is a geographic area containing numerous geologically related mountains. A mountain system or system of mountain ranges, sometimes is used to combine several geological features that are geographically (regionally) related. On Earth, most significant mountain ranges are the result of plate tectonics, though mountain ranges are formed by a range of processes, are found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets., Macedonia ( tr. "Makedonija"), officially the Republic of Macedonia (Macedonian: , tr. "Republika Makedonija"), is a country in the Balkan peninsula in Southeast Europe. It is one of the successor states of the former Yugoslavia, from which it declared independence in 1991.

It has a population of 28,330 and is the seat of the Koani Municipality., A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, and glaciers. A few mountains are isolated summits, but most occur in huge mountain ranges., Osogovo (Bulgarian and Macedonian Cyrillic: ) or Osogovska Planina (  "or"  ) is a mountain and ski resort between southwestern Bulgaria (Kyustendil Province) and northeastern Republic of Macedonia, (Koani and Kriva Palanka municipalities). It is about long and wide, the highest peak being Ruen () at 2251 m, which constitutes the main orthographic knot on the very border between Bulgaria and the Republic of Macedonia. The steepest slope of the mountain is in the west, stretching down from Carev Vrv ( ; "Tsar's Peak")., Mount Etna (or Etna or "Mongibello" , or "â Muntagna") is an active stratovolcano on the east coast of Sicily, Italy, in the Metropolitan City of Catania, between the cities of Messina and Catania. It lies above the convergent plate margin between the African Plate and the Eurasian Plate. It is the tallest active volcano in Europe, currently high, though this varies with summit eruptions. It is the highest peak in Italy south of the Alps. Etna covers an area of with a basal circumference of 140 km. This makes it by far the largest of the three active volcanoes in Italy, being about two and a half times the height of the next largest, Mount Vesuvius. Only Mount Teide in Tenerife (owned by Spain) surpasses it in the whole of the EuropeanNorth-African region.

Spanning continents, Biomes are distinct biological communities that have formed in response to a shared physical climate. Biomes are distinct from habitats, because any biome can comprise a variety of habitats., Vitosha, the ancient "Scomius" or "Scombrus", is a mountain massif, on the outskirts of Sofia, the capital of Bulgaria. Vitosha is one of the symbols of Sofia and the closest site for hiking, alpinism and skiing. Convenient bus lines and rope ways render the mountain easily accessible. Vitosha has the outlines of an enormous dome. The territory of the mountain includes Vitosha nature park that encompasses the best known and most frequently visited parts. The foothills of Vitosha shelter resort quarters of Sofia; Knyazhevo quarter has mineral springs. Vitosha is the oldest nature park in the Balkans.
The mountain emerged as a result of volcanic activity and has been subsequently shaped by the slow folding of the granite rock layers and a series of gradual uplifts of the area. It appears dome shaped at first sight, but the mountain, 19 km long by 17 km wide, actually consists of concentric denudational plateaus rising in tiers one above the other. Vitosha is separated into four main parts whose main ridges gather at a crown known as "Cherni Vrah" (""Black Peak""). This is the highest point of the mountain at 2290 m and is one of 10 peaks of Vitosha over 2000 m in height., Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries., Chepelare is the principal town in Chepelare Municipality, part of Smolyan Province in Southern Bulgaria.

This discharge occurs between electrically charged regions of a cloud (called intra-cloud lightning or IC), between two clouds (CC lightning), or between a cloud and the ground (CG lightning). The charged regions in the atmosphere temporarily equalize themselves through this discharge referred to as a "strike" if it hits an object on the ground, and a flash, if it occurs within a cloud. Lightning causes light in the form of plasma, and sound in the form of thunder. Lightning may be seen and not heard when it occurs at a distance too great for the sound to carry as far as the light from the strike or flash., Golyam Perelik ( Bulgarian :   ) is the highest peak in the Rhodope Mountains , situated 19 km to the west of Smolyan . It makes the Rhodopes the seventh highest Bulgarian mountain range after Rila , Pirin , Stara Planina , Vitosha , Osogovo and Slavyanka . The peak is easily accessible , but currently can not be climbed because a unit of the Bulgarian Army is stationed in its vicinity . Perelik Point on Robert Island , South Shetland Islands is named after Golyam Perelik ., Karst topography is a landscape formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst surface developments might be totally missing., The Rhodopes ( "Rodopi") are a mountain range in Southeastern Europe, with over 83% of its area in southern Bulgaria and the remainder in Greece. Its highest peak, Golyam Perelik, is the seventh highest Bulgarian mountain. The mountain range gives its name to the terrestrial ecoregion Rodope montane mixed forests that belongs in the Temperate broadleaf and mixed forests Biome and the Palearctic ecozone. The region is particularly notable for its karst areas with their deep river gorges, large caves and specific sculptured forms, such as the Trigrad Gorge., The Trigrad Gorge (Bulgarian:  , pronounced ) is a canyon of vertical marble rocks in the Rhodope Mountains. It is in Smolyan Province, one of the southernmost provinces of Bulgaria., Smolyan is a town and ski resort in the far south of Bulgaria near the border with Greece.

As of February 2011, it has a population of 30,283 inhabitants., The Alps are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across eight Alpine countries: Austria, France, Germany, Italy, Liechtenstein, Monaco, Slovenia, and Switzerland. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the FrenchItalian border, and at is the highest mountain in the Alps. The Alpine region area contains about a hundred peaks higher than 4000 metres (just over 13,000 feet)., Subject: golyam perelik, Relation: located_in_the_administrative_territorial_entity, Options: (A) athens (B) atlantic ocean (C) balkans (D) blagoevgrad (E) bulgaria (F) canyon (G) catania (H) center (I) earth (J) east (K) europe (L) european union (M) flora (N) greece (O) hill (P) italy (Q) king (R) kočani (S) kočani municipality (T) kriva palanka (U) kriva palanka municipality (V) kyustendil (W) macedonia (X) most (Y) mountain (Z) national park ([) north (\) northwest (]) norway (^) of (_) river (`) rock (a) romania (b) serbia (c) sicily (d) sierra nevada (e) ski (f) skopje (g) slovenia (h) smolyan province (i) sofia (j) south (k) southwest (l) spain (m) springs (n) summit (o) switzerland (p) the nation (q) the valley (r) thessaloniki (s) turkey (t) west
