Rohtas Plateau
The Rohtas Plateau (also referred to as Kaimur Plateau) is a plateau that lies in the south-western part of the Indian state of Bihar. Surrounding geography A series of fluvial plateaux that run along the Kaimur Range consist of a series of descending plateaux, starting with the Panna Plateau in the west, followed by Bhander Plateau and Rewa Plateau and ending with Rohtas plateau in the east. Description The Rohtas Plateau or Kaimur Plateau comprises about . It is an undulating table land. At Rohtasgarh it attains a height of above sea level. Torrential hill streams have cut deep gorges at the borders of the plateau. Rising abruptly from the plains the sides of the plateau presents a sight of a sharp escarpment. The roof of the tableland at the top is full of small saucer shaped valleys. The rivers flowing over the edges of the plateau and into the deep gorges form numerous waterfalls, with a drop varying from two hundred to six hundred feet. The road approaches to the plateau ...

Irrigation
Irrigation (also referred to as watering) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irrigation, is the oldest form of i ...

Cement
A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource. Cements used in construction are usually inorganic, often lime or calcium silicate based, which can be characterized as hydraulic or the less common non-hydraulic, depending on the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster). Hydraulic cements (e.g., Portland cement) set and become adhesive through a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble and so are quite durable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for lime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals ( grains), vegetables, fruits, cooking oils, m ...

Literacy
Literacy in its broadest sense describes "particular ways of thinking about and doing reading and writing" with the purpose of understanding or expressing thoughts or ideas in written form in some specific context of use. In other words, humans in literate societies have sets of practices for producing and consuming writing, and they also have beliefs about these practices. Reading, in this view, is always reading something for some purpose; writing is always writing something for someone for some particular ends. Beliefs about reading and writing and its value for society and for the individual always influence the ways literacy is taught, learned, and practiced over the lifespan. Some researchers suggest that the history of interest in the concept of "literacy" can be divided into two periods. Firstly is the period before 1950, when literacy was understood solely as alphabetical literacy (word and letter recognition). Secondly is the period after 1950, when literacy slowl ...

Scheduled Tribes
The Scheduled Castes (SCs) and Scheduled Tribes (STs) are officially designated groups of people and among the most disadvantaged socio-economic groups in India. The terms are recognized in the Constitution of India and the groups are designated in one or other of the categories. For much of the period of British rule in the Indian subcontinent, they were known as the Depressed Classes. In modern literature, the ''Scheduled Castes'' are sometimes referred to as Dalit, meaning "broken" or "dispersed", having been popularised by B. R. Ambedkar (1891–1956), a Dalit himself, an economist, reformer, chairman of the Constituent Assembly of India, and Dalit leader during the independence struggle. Ambedkar preferred the term Dalit to Gandhi's term, Harijan, meaning "person of Hari/Vishnu" (or Man of God). In September 2018, the government "issued an advisory to all private satellite channels asking them to 'refrain' from using the nomenclature 'Dalit'", though "rights groups a ...

Sex Ratio
The sex ratio (or gender ratio) is usually defined as the ratio of males to females in a population. As explained by Fisher's principle, for evolutionary reasons this is typically about 1:1 in species which reproduce sexually. Many species deviate from an even sex ratio, either periodically or permanently. Examples include parthenogenic species, periodically mating organisms such as aphids, some eusocial wasps, bees, ants, and termites. The human sex ratio is of particular interest to anthropologists and demographers. In human societies, sex ratios at birth may be considerably skewed by factors such as the age of mother at birth and by sex-selective abortion and infanticide. Exposure to pesticides and other environmental contaminants may be a significant contributing factor as well. As of 2014, the global sex ratio at birth is estimated at 107 boys to 100 girls (1,000 boys per 934 girls).. Types In most species, the sex ratio varies according to the age profile of the ...
