River Delta
A river delta is a landform, archetypically triangular, created by the deposition of the sediments that are carried by the waters of a river, where the river merges with a body of slow-moving water or with a body of stagnant water. The creation of a river delta occurs at the '' river mouth'', where the river merges into an ocean, a sea, or an estuary, into a lake, a reservoir, or (more rarely) into another river that cannot carry away the sediment supplied by the feeding river. Etymologically, the term ''river delta'' derives from the triangular shape (Δ) of the uppercase Greek letter delta. In hydrology, the dimensions of a river delta are determined by the balance between the watershed processes that supply sediment and the watershed processes that redistribute, sequester, and export the supplied sediment into the receiving basin. River deltas are important in human civilization, as they are major agricultural production centers and population centers. They can provide ...

Coast
A coast (coastline, shoreline, seashore) is the land next to the sea or the line that forms the boundary between the land and the ocean or a lake. Coasts are influenced by the topography of the surrounding landscape and by aquatic erosion, such as that caused by wind wave, waves. The geology, geological composition of rock (geology), rock and soil dictates the type of shore that is created. Earth has about of coastline. Coasts are important zones in natural ecosystems, often home to a wide range of biodiversity. On land, they harbor ecosystems, such as freshwater marsh, freshwater or estuary, estuarine wetlands, that are important for birds and other terrestrial animals. In wave-protected areas, coasts harbor salt marshes, mangroves, and seagrass meadow, seagrasses, all of which can provide nursery habitat for finfish, shellfish, and other aquatic animals. Rocky shores are usually found along exposed coasts and provide habitat for a wide range of sessility (motility), sessile ...

Histories (Herodotus)
The ''Histories'' (, ''Historíai''; also known as ''The History'') of Herodotus is considered the founding work of history in Western literature. Although not a fully impartial record, it remains one of the West's most important sources regarding these affairs. Moreover, it established the genre and study of history in the Western world (despite the existence of historical records and chronicles beforehand). ''The'' ''Histories'' also stands as one of the earliest accounts of the rise of the Achaemenid Empire, Persian Empire, as well as the events and causes of the Greco-Persian Wars between the Persian Empire and the Polis, Greek city-states in the 5th century BC. Herodotus portrays the conflict as one between the forces of slavery (the Persians) on the one hand, and freedom (the Athenians and the confederacy of Greek city-states which united against the invaders) on the other. ''The Histories'' was at some point divided into the nine scroll, books that appear in modern editions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herodotus
Herodotus (; BC) was a Greek historian and geographer from the Greek city of Halicarnassus (now Bodrum, Turkey), under Persian control in the 5th century BC, and a later citizen of Thurii in modern Calabria, Italy. He wrote the '' Histories'', a detailed account of the Greco-Persian Wars, among other subjects such as the rise of the Achaemenid dynasty of Cyrus. He has been described as " The Father of History", a title conferred on him by the ancient Roman orator Cicero, and the " Father of Lies" by others. The ''Histories'' primarily cover the lives of prominent kings and famous battles such as Marathon, Thermopylae, Artemisium, Salamis, Plataea, and Mycale. His work deviates from the main topics to provide a cultural, ethnographical, geographical, and historiographical background that forms an essential part of the narrative and provides readers with a wellspring of additional information. Herodotus was criticized in his times for his inclusion of "legends an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aeschylus
Aeschylus (, ; ; /524 – /455 BC) was an ancient Greece, ancient Greek Greek tragedy, tragedian often described as the father of tragedy. Academic knowledge of the genre begins with his work, and understanding of earlier Greek tragedy is largely based on inferences made from reading his surviving plays. According to Aristotle, he expanded the number of characters in the theatre and allowed conflict among them. Formerly, characters interacted only with the Greek chorus, chorus.The remnant of a commemorative inscription, dated to the 3rd century BC, lists four, possibly eight, dramatic poets (probably including Choerilus, Phrynichus, and Pratinas) who had won Dionysia#Known winners of the City Dionysia, tragic victories at the Dionysia before Aeschylus had. Thespis was traditionally regarded the inventor of tragedy. According to another tradition, tragedy was established in Athens in the late 530s BC, but that may simply reflect an absence of records.

Prometheus Bound
''Prometheus Bound'' () is an ancient Greek tragedy traditionally attributed to Aeschylus and thought to have been composed sometime between 479 BC and the terminus ante quem of 424 BC. The tragedy is based on the myth of Prometheus, a Titan who defies Zeus, and protects and gives fire to mankind, for which he is subjected to the wrath of Zeus and punished. British-born author, C.J. Herington, a scholar of classical Greek and Latin, wrote that Aeschylus certainly did not mean ''Prometheus Bound'' to be a "self-contained dramatic unity", and suggests that "most modern students of the subject would probably agree" that ''Prometheus Bound'' was followed by a work with the title ''Prometheus Lyomenos ( Prometheus Unbound)''. Herington adds that "some very slight evidence" indicates that ''Prometheus Unbound'' "may have been followed by a third play", ''Prometheus Pyrphoros ( Prometheus the Fire-Bearer)''; the latter two survive only in fragments. Some scholars have propos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek Drama
A theatrical culture flourished in ancient Greece from 700 BC. At its centre was the city-state of Athens, which became a significant cultural, political, and religious place during this period, and the theatre was institutionalised there as part of a festival called the Dionysia, which honoured the god Dionysus. Tragedy (late 500 BC), comedy (490 BC), and the satyr play were the three dramatic genres emerged there. Athens exported the festival to its numerous colonies. Modern Western theatre comes, in large measure, from the theatre of ancient Greece, from which it borrows technical terminology, classification into genres, and many of its themes, stock characters, and plot elements. Etymology The word , from which the word "tragedy" is derived, is a compound of two Greek words: or "goat" and meaning "song", from . This etymology indicates a link with the practices of the ancient Dionysian cults. It is impossible, however, to know with certainty how these fertility ritua ...

Classical Athenian
Attic Greek is the Greek dialect of the ancient region of Attica, including the ''polis'' of Athens. Often called Classical Greek, it was the prestige dialect of the Greek world for centuries and remains the standard form of the language that is taught to students of Ancient Greek. As the basis of the Hellenistic Koine, it is the most similar of the ancient dialects to later Greek. Attic is traditionally classified as a member or sister dialect of the Ionic branch. Origin and range Greek is the primary member of the Hellenic branch of the Indo-European language family. In ancient times, Greek had already come to exist in several dialects, one of which was Attic. The earliest attestations of Greek, dating from the 16th to 11th centuries BC, are written in Linear B, an archaic writing system used by the Mycenaean Greeks in writing their language; the distinction between Eastern and Western Greek is believed to have arisen by Mycenaean times or before.

Nile Delta
The Nile Delta (, or simply , ) is the River delta, delta formed in Lower Egypt where the Nile River spreads out and drains into the Mediterranean Sea. It is one of the world's larger deltas—from Alexandria in the west to Port Said in the east; it covers of the Mediterranean coastline and is a rich agricultural region. From north to south the delta is approximately in length. The Delta begins slightly down-river from Cairo. Geography From north to south, the delta is approximately in length. From west to east, it covers some of coastline. The delta is sometimes divided into sections, with the Nile dividing into two main distributary, distributaries, the Damietta and the Rosetta, flowing into the Mediterranean at port cities with the same names. In the past, the delta had several distributaries, but these have been lost due to flood management, flood control, silting and changing relief. One such defunct distributary is Wadi Tumilat.

Carbon Sink
A carbon sink is a natural or artificial carbon sequestration process that "removes a greenhouse gas, an aerosol or a precursor of a greenhouse gas from the atmosphere". These sinks form an important part of the natural carbon cycle. An overarching term is carbon pool, which is all the places where carbon on Earth can be, i.e. the atmosphere, oceans, soil, florae, fossil fuel reservoirs and so forth. A carbon sink is a type of carbon pool that has the capability to take up more carbon from the atmosphere than it releases. Globally, the two most important carbon sinks are vegetation and the ocean. Soil is an important carbon storage medium. Much of the organic carbon retained in the soil of agricultural areas has been depleted due to intensive farming. '' Blue carbon'' designates carbon that is fixed via certain marine ecosystems. ''Coastal blue carbon'' includes mangroves, salt marshes and seagrasses. These make up a majority of ocean plant life and store large quantities of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
