Mesa
A mesa is an isolated, flat-topped elevation, ridge or hill, which is bounded from all sides by steep escarpments and stands distinctly above a surrounding plain. Mesas characteristically consist of flat-lying soft sedimentary rocks capped by a more resistant layer or layers of harder rock, e.g. shales overlain by sandstones. The resistant layer acts as a caprock that forms the flat summit of a mesa. The caprock can consist of either sedimentary rocks such as sandstone and limestone; dissected lava flows; or a deeply eroded duricrust. Unlike ''plateau'', whose usage does not imply horizontal layers of bedrock, e.g. Tibetan Plateau, the term ''mesa'' applies exclusively to the landforms built of flat-lying strata. Instead, flat-topped plateaus are specifically known as '' tablelands''.Duszyński, F., Migoń, P. and Strzelecki, M.C., 2019.

Table (landform)
A table or tableland is a butte, flank of a mountain, or mountain, that has a flat top. This kind of landform has numerous names, including: * Butte * Mesa * * Potrero * Tepui * Terrace Terrace may refer to: Landforms and construction * Fluvial terrace, a natural, flat surface that borders and lies above the floodplain of a stream or river * Terrace, a street suffix * Terrace, the portion of a lot between the public sidewalk an ... * Tuya Description The term "flat" is relative when speaking of tables, and often the naming or identification of a table (or table hill or mountain) is based on the appearance of the terrain feature from a distance or from below it. An example is Mesa Verde, Colorado, where the "flat top" of the mountain is both rolling terrain and cut by numerous deep canyons and arroyos, but whose rims appear quite flat from almost all directions, terminating in cliffs.

Butte
__NOTOC__ In geomorphology, a butte () is an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller landforms than mesas, plateaus, and tablelands. The word ''butte'' comes from a French word meaning knoll (but of any size); its use is prevalent in the Western United States, including the southwest where ''mesa'' ( Spanish for "table") is used for the larger landform. Due to their distinctive shapes, buttes are frequently landmarks in plains and mountainous areas. To differentiate the two landforms, geographers use the rule of thumb that a mesa has a top that is wider than its height, while a butte has a top that is narrower than its height. Formation Buttes form by weathering and erosion when hard caprock overlies a layer of less resistant rock that is eventually worn away. The harder rock on top of the butte resists erosion. The caprock provides protection for the less resistant rock below from wind abrasion which leaves i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tepui
A tepui , or tepuy (), is a table-top mountain or mesa found in South America, especially in Venezuela and western Guyana. The word tepui means "house of the gods" in the native tongue of the Pemon, the indigenous people who inhabit the Gran Sabana. Tepuis tend to be found as isolated entities rather than in connected ranges, which makes them the host of a unique array of endemic plant and animal species. Some of the most outstanding tepuis are Auyantepui, Autana, Neblina, and Mount Roraima. They are typically composed of sheer blocks of Precambrian quartz arenite sandstone that rise abruptly from the jungle, giving rise to spectacular natural scenery. Auyantepui is the source of Angel Falls, the world's tallest waterfall. Morphology These table-top mountains are the remains of a large sandstone plateau that once covered the granite basement complex between the north border of the Amazon Basin and the Orinoco, between the Atlantic coast and the Rio Negro. ...

Hill
A hill is a landform that extends above the surrounding terrain. It often has a distinct summit. Terminology The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as steep as a mountain. Geographers historically regarded mountains as hills greater than above sea level, which formed the basis of the plot of the 1995 film ''The Englishman who Went up a Hill but Came down a Mountain''. In contrast, hillwalkers have tended to regard mountains as peaks above sea level. The ''Oxford English Dictionary'' also suggests a limit of and Whittow states "Some authorities regard eminences above as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least high, while the official UK government's definition of a mountain is a summit of or higher. Some definitions include a topographical prominence requirement, typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plain
In geography, a plain is a flat expanse of land that generally does not change much in elevation, and is primarily treeless. Plains occur as lowlands along valleys or at the base of mountains, as coastal plains, and as plateaus or uplands. In a valley, a plain is enclosed on two sides, but in other cases a plain may be delineated by a complete or partial ring of hills, by mountains, or by cliffs. Where a geological region contains more than one plain, they may be connected by a pass (sometimes termed a gap). Coastal plains mostly rise from sea level until they run into elevated features such as mountains or plateaus. Plains are one of the major landforms on earth, where they are present on all continents, and cover more than one-third of the world's land area. Plains can be formed from flowing lava; from deposition of sediment by water, ice, or wind; or formed by erosion by the agents from hills and mountains. Biomes on plains include grassland ( temperate or subtr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plateau
In geology and physical geography, a plateau (; ; ), 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 wide 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. The Columbia Plateau in the north-western United States is an example. They may be formed by upwelling of volcanic magma or extrusion of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North West Australia
The North West, North West Coast, North Western Australia and North West Australia, are usually informal names for the northern regions of the State of Western Australia. However, some conceptions of "North West Australia" have included adjoining parts of the Northern Territory (NT) – or even the entire NT (see below). Major offshore islands include Barrow Island, Monte Bello Islands and the Dampier Archipelago. Apart from land areas, the term "North West" is also used for seabed oil and gas fields of the North West Shelf. Definitions The whole area north of the Murchison River was designated the North District by land regulations gazetted in 1862 by the government of the Colony of Western Australia. From February 1865, the North District was officially administered by a Government Resident, Robert John Sholl, initially based in Camden Harbour, then moved to Roebourne in November 1865. The North-West Land Division, created by legislation in 1887, includes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elbe Sandstone Mountains
The Elbe Sandstone Mountains, also called the Elbe Sandstone Highlands (german: Elbsandsteingebirge; cs, Děčinská vrchovina), are a mountain range straddling the border between the state of Saxony in southeastern Germany and the North Bohemian region of the Czech Republic, with about three-quarters of the area lying on the German side. In both countries, core parts of the mountain range have been declared a national park. The name derives from the sandstone which was carved by erosion. The river Elbe breaks through the mountain range in a steep and narrow valley. The Saxon Switzerland and Bohemian Switzerland national parks, known also as Saxon-Bohemian Switzerland, are located within the territory of Elbe Sandstone Mountains. Geography Extent The Elbe Sandstone Mountains extend on both sides of the Elbe from the Saxon town of Pirna in the northwest toward Bohemian Děčín in the southeast. Their highest peak with is the Děčínský Sněžník in Bohemian Switzerlan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Queensland Government
The Queensland Government is the democratic administrative authority of the Australian state of Queensland. The Government of Queensland, a parliamentary constitutional monarchy was formed in 1859 as prescribed in its Constitution, as amended from time to time. Since the Federation of Australia in 1901, Queensland has been a State of Australia, with the Constitution of Australia regulating the relationships between all state and territory governments and the Australian Government. Under the Australian Constitution, all states and territories (including Queensland) ceded powers relating to certain matters to the federal government. The government is influenced by the Westminster system and Australia's federal system of government. The Governor of Queensland, as the representative of Charles III, King of Australia, holds nominal executive power, although in practice only performs ceremonial duties. In practice executive power lies with the Premier and Cabinet. The Cabinet o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
