Barind Tract
Barind Tract (alternately called the Varendra Tract in English and Borendro Bhumi in Bengali) is the largest Pleistocene era physiographic unit in the Bengal Basin. It covers most of Dinajpur, Rangpur, Pabna, Rajshahi, Bogra, and Joypurhat districts of Rajshahi Division and Rangpur Division in Bangladesh. It is made up of several separate sections in the northwestern part of Bangladesh covering a total area of approximately of mostly old alluvium. On the eastern edge of the tract is a lower fault escarpment. Through the fault troughs run the little Jamuna, Atrai and Lower Punarbhaba rivers. To the west, the main area is tilted up, and to the east this area is tilted downwards. The climate of the tract differs from that of much of India, in that more extreme temperature variations (ranging from 45 degrees Celsius down to five degrees Celsius) are encountered there. It is divided into three units: The Recent Alluvial Fan, the Barind Pleistocene, and the Recent Floodplain. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English (language)
English is a West Germanic language that developed in early medieval England and has since become a English as a lingua franca, global lingua franca. The namesake of the language is the Angles (tribe), Angles, one of the Germanic peoples that Anglo-Saxon settlement of Britain, migrated to Britain after its End of Roman rule in Britain, Roman occupiers left. English is the list of languages by total number of speakers, most spoken language in the world, primarily due to the global influences of the former British Empire (succeeded by the Commonwealth of Nations) and the United States. English is the list of languages by number of native speakers, third-most spoken native language, after Mandarin Chinese and Spanish language, Spanish; it is also the most widely learned second language in the world, with more second-language speakers than native speakers. English is either the official language or one of the official languages in list of countries and territories where English ...

Alluvium
Alluvium (, ) is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not Consolidation (geology), consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present Scientific consensus, consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the French term for al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physiographic Divisions
Physical geography (also known as physiography) is one of the three main branches of geography. Physical geography is the branch of natural science which deals with the processes and patterns in the natural environment such as the atmosphere, hydrosphere, biosphere, and geosphere. This focus is in contrast with the branch of human geography, which focuses on the built environment, and technical geography, which focuses on using, studying, and creating tools to obtain, analyze, interpret, and understand spatial information. The three branches have significant overlap, however. Sub-branches Physical geography can be divided into several branches or related fields, as follows: * Geomorphology is concerned with understanding the surface of the Earth and the processes by which it is shaped, both at the present as well as in the past. Geomorphology as a field has several sub-fields that deal with the specific landforms of various environments, e.g. desert geomorphology and fluvial ...

Geographical Regions
Geography (from Ancient Greek ; combining 'Earth' and 'write', literally 'Earth writing') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines." Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (). The first recorded use of the word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory." ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Bangladesh
The Geology of Bangladesh is affected by the country's location, as Bangladesh is mainly a riverine country. It is the eastern two-thirds of the Ganges and Brahmaputra River, Brahmaputra River delta, river delta plain stretching to the north from the Bay of Bengal. There are two small areas of slightly higher land in the north-centre and north-west composed of old alluvium called the Madhupur Tract and the Barind Tract, and steep, folded, hill ranges of older (Tertiary) rocks along the eastern border. The downwarping of the basement rocks under central and southern Bangladesh result from the pressure of sediments that have been accumulating since the Cretaceous period, mostly a large quantity of carbonate. In the Late Eocene epoch the conditions in the Bay of Bengal changed and these deposits ceased. Structural and tectonic geology In the late Cretaceous, the Indian Plate collided with the Eurasian Plate, after the Indian and African Plate split to form the Indian Ocean du ...

Madhupur Tract
Madhupur Garh, also known as Madhupur Sal Forest or Madhupur Jungle, is a large forested area and elevated region located in the central part of Bangladesh. The Madhupur Garh region stretches from the southern part of Jamalpur District in the north to Fatullah Thana of Narayanganj Sadar Upazila in the south. Most areas of Tangail and Gazipur Districts, as well as Dhaka City, are included within this Garh region. The northern part of the Garh is known as Madhupur Garh, and the southern part is known as Bhawal Garh. Madhupur National Park has been formed from the portion of the Garh located in Madhupur Upazila, and Bhawal National Park has been formed from a portion located in Gazipur. After the Madhupur forest came under the jurisdiction of the Forest Department in 1962, initiatives were taken to conserve the biodiversity of the forest. According to the Bangladesh Wildlife (Preservation) Order of 1974, with the aim of biodiversity conservation, an area of 84,366 hectares of ...

Atrai River
Atrai River (also spelt as Atreyee) () flows in West Bengal in India and northern parts of Bangladesh. In ancient times the river was called Atreyee and finds a mention in the Mahabharata, one of the two Sanskrit epics of ancient India. It is linked with Jorapani river, Fuleswari river, and Karatoya River. The Atrai originates in Siliguri ward no 40, near Baikanthapur forest of West Bengal and after flowing through Dinajpur District of Bangladesh, it enters India again. It passes through Kumarganj and Balurghat community development blocks in Dakshin Dinajpur district. The river then renters Bangladesh. It splits into two rivers—the Gabura and the Kankra in Dinajpur district. It crosses the Barind Tract and flows into Chalan Beel. The river serves as a perennial source of fishing, even though it is often the cause of flooding in many areas during monsoon A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitat ...

Jamuna River (Bangladesh)
The Jamuna River () is one of the three main rivers of Bangladesh. The two other major rivers in Bangladesh are the Padma River, Padma and the Meghna River, Meghna. The Jamuna is the lower stream of the Brahmaputra River, which originates in Tibet Autonomous Region, Tibet as Yarlung Tsangpo, before flowing through India and then southwest into Bangladesh. The Jamuna flows south and joins the Padma River near Goalundo Ghat, before meeting the Meghna River near Chandpur District, Chandpur. The Meghna then flows into the Bay of Bengal. The Brahmaputra-Jamuna is a classic example of a braided river and is highly susceptible to River channel migration, channel migration and Avulsion (river), avulsion. It is characterised by a network of interlacing channels with numerous sandbars enclosed between them. The sandbars, known in Bengali language, Bengali as ''chars'', do not occupy a permanent position. The river deposits them in one year, very often to be destroyed later, and redeposi ...

Trough (geology)
In geology, a trough is a linear structural depression that extends laterally over a distance. Although it is less steep than a ''trench'', a trough can be a narrow basin or a geologic rift. These features often form at the rim of tectonic plates. There are various oceanic troughs on the ocean floors. Examples of oceanic troughs * Benue Trough * Cayman Trough * Hesperides Trough * Kings Trough * Mariana Trough * Nankai Trough * Northumberland Trough * Okinawa Trough in the East China Sea * Rockall Trough and others along the rift of the mid-oceanic ridge * Salton Trough * South Shetland Trough * Suakin TroughDinwiddie, Robert et al.

Escarpment
An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations. Due to the similarity, the term '' scarp'' may mistakenly be incorrectly used interchangeably with ''escarpment.'' ''Escarpment'' referring to the margin between two landforms, and ''scarp'' referring to a cliff or a steep slope. In this usage an escarpment is a ridge which has a gentle slope on one side and a steep scarp on the other side. More loosely, the term ''scarp'' also describes a zone between a coastal lowland and a continental plateau which shows a marked, abrupt change in elevation caused by coastal erosion at the base of the plateau. Formation and description Scarps are generally formed by one of two processes: either by differential erosion of sedimentary rocks, or by movement of the Earth's crust at a geologic fault. The first process is the more common type: the escarpment is a transition from one seri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
