Bank (geography)

In geography a bank generally refers to the land alongside a body of water. Various structures are referred to as banks in different fields of geography.

In limnology, the study of inland waters, a stream bank or river bank is the terrain alongside the bed of a river, creek, or stream. Stream banks are of particular interest in fluvial geography, which studies the processes associated with rivers and streams and the deposits and landforms created by them. The shoreline of ponds, swamps, estuarys, reservoirs, or lakes are also of interest in limnology, and are sometimes referred to as banks. The grade of these banks or shorelines can vary from vertical to a shallow slope.

In freshwater ecology, banks are of interest as the location of riparian habitats. Riparian zones occur along upland and lowland river and stream beds. The ecology around and depending on a marsh, swamp, slough, or estuary, sometimes called a bank, is likewise studied in freshwater ecology.

Banks are also of interest in navigation, where the term can refer either to a barrier island or a submerged plateau. A barrier island is a long narrow island composed of sand and forming a barrier between an island lagoon or sound and the ocean. A submerged plateau is a relatively flat topped elevation of the sea floor at shallow depth (generally less than 200m), typically on the continental shelf or near an island.

Bank

A bank is a financial institution that creates credit by lending money to a borrower, thereby creating a corresponding deposit on the bank's balance sheet. Lending activities can be performed either directly or indirectly through capital markets. Due to their importance in the financial system and influence on national economies, banks are highly regulated in most countries. Most nations have institutionalized a system known as fractional reserve banking under which banks hold liquid assets equal to only a portion of their current liabilities. In addition to other regulations intended to ensure liquidity, banks are generally subject to minimum capital requirements based on an international set of capital standards, known as the Basel Accords.

Banking in its modern sense evolved in the 14th century in the rich cities of Renaissance Italy but in many ways was a continuation of ideas and concepts of credit and lending that had their roots in the ancient world. In the history of banking, a number of banking dynasties — notably, the Medicis, the Fuggers, the Welsers, the Berenbergs and the Rothschilds — have played a central role over many centuries. The oldest existing retail bank is Monte dei Paschi di Siena, while the oldest existing merchant bank is Berenberg Bank.

Rampart (fortification)

A rampart in fortification architecture is a length of bank or wall forming part of the defensive boundary of a castle, hillfort, settlement or other fortified site. It is usually broad-topped and made of excavated earth or masonry or a combination of the two.

Early fortifications

Many types of early fortification, from prehistory through to the Early Middle Ages, employed earth ramparts usually in combination with external ditches to defend the outer perimeter of a fortified site or settlement.Hillforts, ringforts or "raths" and ringworks all made use of ditch and rampart defences, and of course they are the characteristic feature of circular ramparts. The ramparts could be reinforced and raised in height by the use of palisades. This type of arrangement was a feature of the motte and bailey castle of northern Europe in the early medieval period.

Types of rampart

The composition and design of ramparts varied from the simple mounds of earth and stone, known as dump ramparts, to more complex earth and timber defences (box ramparts and timberlaced ramparts), as well as ramparts with stone revetments. One particular type, common in Central Europe, used earth, stone and timber posts to form a Pfostenschlitzmauer or "post-slot wall". Vitrified ramparts were composed of stone that was subsequently fired, possibly to increase its strength.

Bank (card game)

Bank, also known also as "Polish Bank" or "Russian Bank," is the name of a comparing card game. The game requires a standard 52-card deck and five or six players.

Rules

At the start of the game, each player contributes an arranged stake to the pool. The dealer gives three cards to each player and turns up another; if this is not lower than an eight (ace is lowest), the dealer continues turning up cards until such a card is exposed. The player on the dealer's left, without touching or looking at the three cards received, can bet the amount of the pool, or any part of it, that among those cards is one that is higher (of the same suit) than the turn-up. If the player wins, the player takes the amount from the pool; if the player loses, the player pays that amount to the pool. Each player does the same in turn, the dealer last. Whenever the pool is exhausted, a fresh stake is put into the pool. After a round is over the deal passes. No player may touch any cards received until making a bet; the penalty is a fine to the pool of twice the stake, and the loss of the right to bet during that round.

Geography (disambiguation)

Geography is the study of the earth and its features, inhabitants, and phenomena.

Geography may also refer to:

Eratosthenes

Eratosthenes of Cyrene (/ɛrəˈtɒsθəniːz/; Greek: Ἐρατοσθένης, IPA: [eratostʰénɛːs]; c. 276 BC – c. 195/194 BC) was a Greek mathematician, geographer, poet, astronomer, and music theorist. He was a man of learning, becoming the chief librarian at the Library of Alexandria. He invented the discipline of geography, including the terminology used today.

He is best known for being the first person to calculate the circumference of the Earth, which he did by applying a measuring system using stadia, which was a standard unit of measure during that time period. His calculation was remarkably accurate. He was also the first to calculate the tilt of the Earth's axis (again with remarkable accuracy). Additionally, he may have accurately calculated the distance from the Earth to the Sun and invented the leap day. He created the first map of the world incorporating parallels and meridians, based on the available geographical knowledge of the era.

Eratosthenes was the founder of scientific chronology; he endeavored to revise the dates of the chief literary and political events from the conquest of Troy. In number theory, he introduced the sieve of Eratosthenes, an efficient method of identifying prime numbers.

Geographica

The Geographica (Ancient Greek: Γεωγραφικά Geōgraphiká), or Geography, is an encyclopedia of geographical knowledge, consisting of 17 'books', written in Greek by Strabo, an educated citizen of the Roman empire of Greek descent. Work can have begun on it no earlier than 20 BC. A first edition was published in 7 BC followed by a gap, resumption of work and a final edition no later than 23 AD in the last year of Strabo's life. Strabo probably worked on his Geography and now missing History concurrently, as the Geography contains a considerable amount of historical data. Except for parts of Book 7, the complete work is known.

Title of the work

Strabo refers to his Geography within it by several names:

Apart from the "outline", two words recur, "earth" and "country." Something of a theorist, Strabo explains what he means by Geography and Chorography:
