Sky

The sky (or celestial dome) is everything that lies above the surface of the Earth, including the atmosphere and outer space.

In the field of astronomy, the sky is also called the celestial sphere. This is viewed from Earth's surface as an imaginary dome where the sun, stars, planets, and the moon are seen to be traveling. The celestial sphere is conventionally divided into regions called constellations. Usually, the term sky is used informally as the point of view from the Earth's surface; however, the meaning and usage can vary. In some cases, such as in discussing the weather, the sky refers to only the lower, more dense portions of the atmosphere.

During daylight, the sky appears to be blue because air scatters blue sunlight more than it scatters red. At night, the sky appears to be a mostly dark surface or region scattered with stars. During the day, the Sun can be seen in the sky unless obscured by clouds. In the night sky (and to some extent during the day) the moon, planets and stars are visible in the sky. Some of the natural phenomena seen in the sky are clouds, rainbows, and aurorae. Lightning and precipitation can also be seen in the sky during storms. Birds, insects, aircraft, and kites are often considered to fly in the sky. Due to human activities, smog during the day and light pollution during the night are often seen above large cities.

South America

South America is a continent located in the Western Hemisphere, mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere. It is also considered as a subcontinent of the Americas, which is the model used in Spanish-speaking nations and most of South America.

It is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. It includes twelve sovereign states – Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela – and two non-sovereign areas – French Guiana, an overseas department of France, and the Falkland Islands, a British Overseas Territory (though disputed by Argentina). In addition to this, the ABC islands of the Netherlands and Trinidad and Tobago may also be considered part of South America.

South America has an area of 17,840,000 square kilometers (6,890,000 sq mi). Its population as of 2005 has been estimated at more than 371,090,000. South America ranks fourth in area (after Asia, Africa, and North America) and fifth in population (after Asia, Africa, Europe, and North America). The most populous countries are Brazil, Colombia, Argentina, Venezuela and Peru.

Brazil

Coordinates: 10°S 52°W / 10°S 52°W / -10; -52

Brazil (ⁱ/brəˈzɪl/; Portuguese: Brasil [bɾaˈziw] ), officially the Federative Republic of Brazil (Portuguese: República Federativa do Brasil,  listen  ), is the largest sovereign state in both South America and the Latin American region. It is the world's fifth-largest country, both by geographical area and by population. It is the largest Portuguese-speaking country in the world, and the only one in the Americas.

Bounded by the Atlantic Ocean on the east, Brazil has a coastline of 7,491 km (4,655 mi). It borders all other South American countries except Ecuador and Chile and occupies 47.3 percent of the continent of South America. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection.

Seppuku

Seppuku (切腹 or せっぷく), "stomach- or abdomen-cutting," is a form of Japanese ritual suicide by disembowelment. Seppuku was originally reserved for samurai. Part of the samurai bushido honor code, seppuku was used either voluntarily by samurai to die with honor rather than fall into the hands of their enemies (and likely suffer torture) or as a form of capital punishment for samurai who had committed serious offenses, or performed because they had brought shame to themselves. The ceremonial disembowelment, which is usually part of a more elaborate ritual and performed in front of spectators, consists of plunging a short blade, traditionally a tantō, into the abdomen and drawing the blade from left to right, slicing the abdomen open.

Etymology

A Japanese form of ritual suicide, the term "seppuku" derives from the two Sino-Japanese roots setsu 切 ("to cut", from Middle Chinese tset) and puku 腹 ("belly", from MC pjuwk). It is also known as harakiri (腹切り, "cutting the belly"), a term more widely familiar outside Japan, and which is written with the same kanji as seppuku, but in reverse order with an okurigana. In Japanese, the more formal seppuku, a Chinese on'yomi reading, is typically used in writing, while harakiri, a native kun'yomi reading, is used in speech. Ross notes,
