Aleutian Islands
The Aleutian Islands (; ; ale, Unangam Tanangin,”Land of the Aleuts", possibly from Chukchi ''aliat'', "island"), also called the Aleut Islands or Aleutic Islands and known before 1867 as the Catherine Archipelago, are a chain of 14 large volcanic islands and 55 smaller islands. Most of the Aleutian Islands belong to the U.S. state of Alaska, but some belong to the Russian federal subject of Kamchatka Krai. They form part of the Aleutian Arc in the Northern Pacific Ocean, occupying a land area of 6,821 sq mi (17,666 km2) and extending about westward from the Alaska Peninsula toward the Kamchatka Peninsula in Russia, and act as a border between the Bering Sea to the north and the Pacific Ocean to the south. Crossing longitude 180°, at which point east and west longitude end, the archipelago contains both the westernmost part of the United States by longitude ( Amatignak Island) and the easternmost by longitude ( Semisopochnoi Island). The westernmost U.S. islan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Alaska Peninsula
The Alaska Peninsula (also called Aleut Peninsula or Aleutian Peninsula, ale, Alasxix̂; Sugpiaq: ''Aluuwiq'', ''Al'uwiq'') is a peninsula extending about to the southwest from the mainland of Alaska and ending in the Aleutian Islands. The peninsula separates the Pacific Ocean from Bristol Bay, an arm of the Bering Sea. In literature (especially Russian) the term "Alaska Peninsula" was used to denote the entire northwestern protrusion of the North American continent, or all of what is now the state of Alaska, exclusive of its panhandle and islands. The Lake and Peninsula borough, the Alaskan equivalent of a county, is named after the peninsula. The Alaska/Aleutian Peninsula is also grouped into Southwest Alaska. The other largest peninsulas in Alaska include the Kenai Peninsula and Seward Peninsula. Geography The base of the Alaska Peninsula extends out from the end of the Alaska Range. The Aleutian Range is a highly active volcanic mountain range which runs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ResearchGate
ResearchGate is a European commercial social networking site for scientists and researchers to share papers, ask and answer questions, and find collaborators. According to a 2014 study by ''Nature'' and a 2016 article in ''Times Higher Education'', it is the largest academic social network in terms of active users, although other services have more registered users, and a 2015–2016 survey suggests that almost as many academics have Google Scholar profiles. While reading articles does not require registration, people who wish to become site members need to have an email address at a recognized institution or to be manually confirmed as a published researcher in order to sign up for an account. Members of the site each have a user profile and can upload research output including papers, data, chapters, negative results, patents, research proposals, methods, presentations, and software source code. Users may also follow the activities of other users and engage in discussions with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of The United States Pacific Mountain System
The Pacific Coast Ranges (officially gazetted as the Pacific Mountain System in the United States) are the series of mountain ranges that stretch along the West Coast of North America from Alaska south to Northern and Central Mexico. Although they are commonly thought to be the westernmost mountain range of the continental United States and Canada, the geologically distinct Insular Mountains of Vancouver Island lie further west. The Pacific Coast Ranges are part of the North American Cordillera (sometimes known as the Western Cordillera, or in Canada, as the Pacific Cordillera and/or the Canadian Cordillera), which includes the Rocky Mountains, the Columbia Mountains, the Interior Mountains, the Interior Plateau, the Sierra Nevada, the Great Basin mountain ranges, and other ranges and various plateaus and basins. The Pacific Coast Ranges designation, however, only applies to the Western System of the Western Cordillera,S. Holland, ''Landforms of British Columbia'', BC Govt. 1976 ...

Ring Of Fire
The Ring of Fire (also known as the Pacific Ring of Fire, the Rim of Fire, the Girdle of Fire or the Circum-Pacific belt) is a region around much of the rim of the Pacific Ocean where many volcanic eruptions and earthquakes occur. The Ring of Fire is a horseshoe-shaped belt about long and up to about wide. The Ring of Fire includes the Pacific coasts of South America, North America and Kamchatka, and some islands in the western Pacific Ocean. Although there is consensus among geologists about almost all areas which are included in the Ring of Fire, they disagree about the inclusion or exclusion of a few areas, for example, the Antarctic Peninsula and western Indonesia. The Ring of Fire is a direct result of plate tectonics: specifically the movement, collision and destruction of lithospheric plates (e.g. the Pacific Plate) under and around the Pacific Ocean. The collisions have created a nearly continuous series of subduction zones, where volcanoes are created and ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commander Islands
The Commander Islands, Komandorski Islands, or Komandorskie Islands (russian: Командо́рские острова́, ''Komandorskiye ostrova'') are a series of treeless, sparsely populated Russian islands in the Bering Sea located about east of the Kamchatka Peninsula in the Russian Far East. The islands consist of Bering Island ( by ), Medny Island ( by ) and fifteen smaller ones (islets and rocks), the largest of which are ''Tufted Puffin Rock (Kamen Toporkov'' or ''Ostrov Toporkov)'', , and Kamen Ariy, which are between and west of the only settlement, Nikolskoye. Administratively, they compose Aleutsky District of Kamchatka Krai in Russia. Geography The Commander Islands are the westernmost of the Aleutian Islands, most of which are part of the US state of Alaska, and are separated from the closest US island, Attu Island, and the rest of the chain by . Between the two runs the International Date Line. The relief is somewhat diverse, encompassing folded-block m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Date Line
The International Date Line (IDL) is an internationally accepted demarcation on the surface of Earth, running between the South and North Poles and serving as the boundary between one calendar day and the next. It passes through the Pacific Ocean, roughly following the 180° line of longitude and deviating to pass around some territories and island groups. Crossing the date line eastbound decreases the date by one day, while crossing the date line westbound increases the date. Geography Circumnavigating the globe People traveling westward around the world must set their clocks: *Back by one hour for every 15° of longitude crossed, and *Forward by 24 hours upon crossing the International Date Line. People traveling eastward must set their clocks: *Forward by one hour for every 15° of longitude crossed, and *Back by 24 hours upon crossing the International Date Line. Failing to do this would make their time inaccurate to the local time. The Arab geographer Abul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attu Island
Attu ( ale, Atan, russian: Атту, link=no) is an island in the Near Islands (part of the Aleutian Islands chain). It is the westernmost point of the U.S. state of Alaska. The island became uninhabited in 2010, making it the largest uninhabited island to be politically part of the United States. (archived June 25, 2017) The Battle of Attu was the site of the only World War II land battle fought in the United States. The battlefield area is a U.S. National Historic Landmark. Attu Station, a former Coast Guard LORAN station, is located at , making it one of the westernmost points of the United States relative to the rest of the country. However, since it is in the Eastern Hemisphere, being on the opposite side of the 180° longitude line of the contiguous 48 states, it can also be considered one of the easternmost points of the country (a second Aleutian Island, Semisopochnoi Island at 179°46′E, is the easternmost location in the United States by this definition).

Archipelago
An archipelago ( ), sometimes called an island group or island chain, is a chain, cluster, or collection of islands, or sometimes a sea containing a small number of scattered islands. Examples of archipelagos include: the Indonesian Archipelago, the Andaman and Nicobar Islands, the Lakshadweep Islands, the Galápagos Islands, the Japanese archipelago, the Philippine Archipelago, the Maldives, the Balearic Islands, The Bahamas, the Aegean Islands, the Hawaiian Islands, the Canary Islands, Malta, the Azores, the Canadian Arctic Archipelago, the British Isles, the islands of the Archipelago Sea, and Shetland. They are sometimes defined by political boundaries. For example, the Gulf archipelago off the northeastern Pacific coast forms part of a larger archipelago that geographically includes Washington state's San Juan Islands; while the Gulf archipelago and San Juan Islands are geographically related, they are not technically included in the same archipelago ...
