Transylvanian Basin
The Transylvanian Plateau (; ) is a plateau in central Romania. Description The plateau lies within and takes its name from the historical region of Transylvania, and is almost entirely surrounded by the Eastern, Southern and Romanian Western branches of the Carpathian Mountains. The area includes the Transylvanian Plain. It is improperly called a plateau, for it does not possess extensive plains, but is formed of a network of valleys of various size, ravines and canyons, united together by numerous small mountain ranges, which attain a height of above the altitude of the valley. The plateau has a continental climate. Temperature varies a great deal in the course of a year, with warm summers contrasted by very cold winters. Vast forests cover parts of the plateau and the mountains. The mean elevation is . Subdivisions The Transylvanian Plateau is divided into three areas: * (''Podișul Someșan'' or ''Podișul Someșelor''); the northern part. *Transylvanian Plain (''Câm ...

Transylvanian Plain
The Transylvanian Plain (; , ) is an ethnogeographical area in Transylvania, Romania, located between the Someșul Mare and the Someșul Mic rivers to the north and west and the Mureș River Mureș may refer to: * Mureș County, Romania * Mureș (river) in Romania and Hungary (''Maros'') * Mureș culture, a Bronze Age culture from Romania See also * Târgu Mureș, the capital of Mureș County * Ocna Mureș, a town in Alba Cou ... to the south and east. It is populated by both ethnic Romanians and ethnic Hungarians. The Transylvanian Plain can be divided into two parts: a hilly one in the northeast and a flatter one in the south and west. Important villages in the Transylvanian Plain include Sic (in Hungarian, ''Szék''; a former salt-mining town), Mociu (''Mócs''), Jucu (''Zsuk''), Band (''Mezőbánd''), Suatu (''Magyarszovát''), and Unguraș (''Bálványosváralja'').

Plateaus Of Romania
In geology and physical geography, a plateau (; ; : plateaus or plateaux), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wider ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, plate tectonics movements, and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. They may be formed by upwelling of volcanic magma or extrusion of lava. The underlining mechanism in forming plateaus from up ...

Romanian Carpathians
The Romanian Carpathians () are a section of the Carpathian Mountains, within the borders of modern Romania. The Carpathians are a "subsystem" of the Alps-Himalaya System and are further divided into "provinces" and "subprovinces". This is an overview of the geological subdivisions of the Romanian section of the Carpathian Mountains. The broadest divisions are shown in the map on the right. The last level of the division, i.e. the actual mountain ranges and basins, is usually called "units". The lowest-level detail for those units is maintained on separate pages. Naming conventions Traditional Romanian naming conventions differ from this list. In Romania, it is usual to divide the Eastern Carpathians in Romanian territory into three geographical groups (North, Centre, South), instead in Outer and Inner Eastern Carpathians. The Transylvanian Plateau is encircled by, and geologically a part of, the Carpathians, but it is not a mountainous region and its inclusion is disputed i ...

Salt Dome
A salt dome is a type of structural dome formed when salt (or other evaporite minerals) intrudes into overlying rocks in a process known as diapirism. Salt domes can have unique surface and subsurface structures, and they can be discovered using techniques such as seismic reflection. They are important in petroleum geology as they can function as petroleum traps. Formation Diagram showing formation of salt domes Stratigraphically, salt basins developed periodically from the Proterozoic to the Neogene. The formation of a salt dome begins with the deposition of salt in a restricted basin. In these basins, the outflow of water exceeds inflow. Specifically, the basin loses water through evaporation, resulting in the precipitation and deposition of salt. While the rate of sedimentation of salt is significantly larger than the rate of sedimentation of clastics, it is recognized that a single evaporation event is rarely enough to produce the vast quantities of salt needed to f ...

Methane
Methane ( , ) is a chemical compound with the chemical formula (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it is difficult because it is a gas at standard temperature and pressure. In the Earth's atmosphere methane is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. Methane is an Organic chemistry, organic Organic compound, compound, and among the simplest of organic compounds. Methane is also a hydrocarbon. Naturally occurring methane is found both below ground and under the seafloor and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the Atmosphere of Earth, atmosphere, it is known as atmospheric methane. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continental Climate
Continental climates often have a significant annual variation in temperature (warm to hot summers and cold winters). They tend to occur in central and eastern parts of the three northern-tier continents (North America, Europe, and Asia), typically in the middle latitudes (40 to 55 or 60 degrees north), often within large landmasses, where prevailing winds blow overland bringing some precipitation, and temperatures are not moderated by oceans. Continental climates occur mostly in the Northern Hemisphere due to the large landmasses found there. Most of northeastern China, eastern and southeastern Europe, much of Russia south of the Arctic Circle, central and southeastern Canada, and the central and northeastern United States have this type of climate. Continentality is a measure of the degree to which a region experiences this type of climate. In continental climates, precipitation tends to be moderate in amount, concentrated mostly in the warmer months. Only a few areas—in th ...

Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canyon
A canyon (; archaic British English spelling: ''cañon''), gorge or chasm, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examples of mountain- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
