The principle is that all the coldest air from inside the igloo runs downward off the terraces & collects in the bottom, thus MORE
Indigenous peoples of North America
An igloo (Inuit language: iglu, ᐃᒡᓗ [iɣˈlu] (plural: igluit ᐃᒡᓗᐃᑦ [iɣluˈit]) or snowhouse is a type of shelter built of snow, originally built by the Inuit.
Although igloos are usually associated with all Inuit, they were predominantly constructed by people of Canada's Central Arctic and Greenland's Thule area. Other Inuit people tended to use snow to insulate their houses, which were constructed from whalebone and hides. Snow is used because the air pockets trapped in it make it an insulator. On the outside, temperatures may be as low as −45 °C (−49 °F), but on the inside the temperature may range from −7 °C (19 °F) to 16 °C (61 °F) when warmed by body heat alone.
The indigenous peoples of the Americas are the pre-Columbian inhabitants of North and South America and their descendants. Pueblos indígenas (indigenous peoples) is a common term in Spanish-speaking countries. Aborigen (aboriginal/native) is used in Argentina, while "Amerindian" is used in Guyana but not commonly used in other countries. Indigenous peoples are commonly known in Canada as Aboriginal peoples, which include First Nations, Inuit, and Métis peoples. Indigenous peoples of the United States are commonly known as Native Americans or American Indians, and Alaskan Natives.
According to a prevailing New World migration model, migrations of humans from Eurasia to the Americas took place via Beringia, a land bridge which connected the two continents across what is now the Bering Strait. The most recent migration could have taken place around 12,000 years ago, with the earliest period remaining a matter of some unresolved contention. These early Paleo-Indians soon spread throughout the Americas, diversifying into many hundreds of culturally distinct nations and tribes. According to the oral histories of many of the indigenous peoples of the Americas, they have been living there since their genesis, described by a wide range of traditional creation accounts.
Club Penguin is a massively multiplayer online game (MMO) involving a virtual world containing a range of online games and activities, created by New Horizon Interactive using SmartFoxServer. Players use cartoon penguin-avatars and play in a winter-set virtual world. After beta-testing, Club Penguin was made available to the general public on October 24, 2005 and has since expanded into a large online community —growing to the extent that by late 2007, it was claimed that Club Penguin had over 30 million user accounts. As of July 2013, Club Penguin has over 200 million registered user accounts.
While free memberships are available, revenue is predominantly raised through paid memberships which allow players to access a range of additional features, such as the ability to purchase virtual clothing, furniture, and in-game pets called "puffles" for their penguins through the use of in-game currency.]citation needed[ The success of Club Penguin led to New Horizon being purchased by The Walt Disney Company in August 2007 for the sum of 350 million dollars, with an additional 350 million dollars in bonuses should specific targets be met by 2009.
