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 as well as entirety of Uttar Dinajpur, Dakshin Dinajpur and most of Maldah districts in West Bengal, India. It is made up of several separate sections in the northwestern part of Bangladesh, and, northern part of West Bengal, India 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 de ...

English (language)
English is a West Germanic language of the Indo-European language family, with its earliest forms spoken by the inhabitants of early medieval England. It is named after the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain. Existing on a dialect continuum with Scots, and then closest related to the Low Saxon and Frisian languages, English is genealogically West Germanic. However, its vocabulary is also distinctively influenced by dialects of France (about 29% of Modern English words) and Latin (also about 29%), plus some grammar and a small amount of core vocabulary influenced by Old Norse (a North Germanic language). Speakers of English are called Anglophones. The earliest forms of English, collectively known as Old English, evolved from a group of West Germanic (Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century and further mutated by Norse-speaking Viking settlers starting in the 8th and 9th ...

Dakshin Dinajpur
Dakshin Dinajpur () or South Dinajpur is a district in the Indian state of West Bengal, India. It was created on 1 April 1992 by the division of the erstwhile West Dinajpur District. The Headquarter (sadar) of the district is at Balurghat. It comprises two subdivisions: Balurghat and Gangarampur. According to the 2011 census, it is the third least populous district of West Bengal (out of 23). History The erstwhile Dinajpur District, at the time of the partition of India, was split up into West Dinajpur district and East Dinajpur. The East Dinajpur district, now called Dinajpur, became part of East Pakistan (now Bangladesh). The West Dinajpur district was enlarged in 1956, when States Reorganisation Act recommendations were implemented, with the addition of some areas of Bihar. The district was bifurcated into Uttar Dinajpur and Dakshin Dinajpur on 1 April 1992. Economy Dakshin Dinajpur is predominantly an agricultural district with a large area of land under cultivation ... [...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 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 during the Triassic.

Madhupur Tract
Madhupur tract is a large upland area of 4,244 km2 in north central part of Bangladesh, stretching from east of Jamalpur in the north, to Fatullah and Narayanganj, in the south. The tract is mostly one large tract, unlike the Barind Tract. It is approximately one to ten metres above the nearby floodplains. The tract is considered as an area of jungle-covered of old alluvium. It is an elevated plateau, with hillocks of varying heights, ranging from 30 to 60 feet. There are also cultivated valleys.

Punarbhaba River
The Punarbhaba (also ''Poonorvoba''; bn, পুনর্ভবা নদী) is a river of Bangladesh and West Bengal, of total length about and a width of and a mean depth of It originates from the lowlands of Thakurgaon District of Bangladesh. The river's upper part is a few kilometres west of Atrai. Dinajpur town of Bangladesh is situated on the east bank of the river. It flows through Gangarampur and Tapan community development blocks of Dakshin Dinajpur district of West Bengal. After flowing to the south, this river meets with the Dhepa River. Ultimately it flows into the Ganges The Ganges ( ) (in India: Ganga ( ); in Bangladesh: Padma ( )).

Atrai River
Atrai River (also spelt as Atreyee) ( bn, আত্রাই/আত্রেয়ী নদী) flows in West Bengal 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. It originates in Siliguri ward no 40, near baikanthapur forest West Bengal and then 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 monsoons. Total length of this river is approximately . The maximum depth of ...

Jamuna River (Bangladesh)
The Jamuna River ( bn, যমুনা ''Jomuna'') is one of the three main rivers of Bangladesh. It is the lower stream of the Brahmaputra River, which originates in Tibet as Yarlung Tsangpo, before flowing into India and then southwest into Bangladesh. The Jamuna flows south and joins the Padma River (''Pôdda''), near Goalundo Ghat, before meeting the Meghna River near Chandpur. It then flows into the Bay of Bengal as the Meghna River. The Brahmaputra-Jamuna is a classic example of a braided river and is highly susceptible to channel migration and avulsion. It is characterised by a network of interlacing channels with numerous sandbars enclosed between them. The sandbars, known in Bengali as ''chars'', do not occupy a permanent position. The river deposits them in one year, very often to be destroyed later, and redeposits them in the next rainy season. The process of bank and deposit erosion together with redeposition has been going on continuously, making it difficult to ...

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.

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. The terms ''scarp'' and ''scarp face'' are often used interchangeably with ''escarpment''. Some sources differentiate the two terms, with ''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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Alluvium
Alluvium (from Latin ''alluvius'', from ''alluere'' 'to wash against') 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 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 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 F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
India
India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ...
