180th Meridian
The 180th meridian or antimeridian is the meridian (geography), meridian 180° both east and west of the prime meridian in a Geographic coordinate system, geographical coordinate system. The longitude at this line can be given as either east or west. On Earth, the prime and 180th meridians form a great ellipse that divides the planet into the Western Hemisphere, Western and Eastern Hemispheres. Locations The antimeridian passes mostly through the open waters of the Pacific Ocean but also runs across land in Russia, Fiji, and Antarctica. An important function of this meridian is its use as the basis for the International Date Line, which snakes around national borders to maintain date consistency within the territories of Russia, the United States, Kiribati, Fiji and New Zealand. Starting at the North Pole of the Earth and heading south to the South Pole, the 180th meridian passes through: The meridian also passes between (but not particularly close to): *through the Aleu ...

Aleutian Arc
The Aleutian Arc is a large volcanic arc of islands extending from the Southwest tip of the U.S. state of Alaska to the Kamchatka Peninsula of the Russian Federation. It consists of a number of active and dormant volcanoes that have formed as a result of the subduction of the Pacific plate beneath the North American plate along the Aleutian Trench. Although taking its name from the Aleutian Islands, this term is a Geology, geologic grouping rather than a Geography, geographic one. The Aleutian Arc extends through the Alaska Peninsula following the Aleutian Range through the Aleutian Islands. The arc makes up a sizable portion of the Ring of Fire, Pacific Ring of Fire, and is known for generating many Earthquake, strong magnitude earthquakes (magnitude 6–6.7) as well as its volcanism. Formation and geologic features Formation The Aleutian Arc reflects subduction of the Pacific plate beneath the North American plate. It extends from the Kamchatka Peninsula in the west to th ...

Volcanic Island
Geologically, a volcanic island is an island of volcanic origin. The term high island can be used to distinguish such islands from low islands, which are formed from sedimentation or the uplifting of coral reefs (which have often formed on sunken volcanoes). Definition and origin There are a number of volcanic islands that rise no more than above sea level, often classified as islets or rocks, while some low islands, such as Banaba, Henderson Island, Makatea, Nauru, and Niue, rise over above sea level. The two types of islands are often found in proximity to each other, especially among the islands of the South Pacific Ocean, where low islands are found on the fringing reefs that surround most volcanic islands. Volcanic islands normally rise above a hotspot or subduction zone. Habitability Volcanic islands usually range in size between . Islands above a certain size usually have fresh groundwater, while low islands often do not, so volcanic islands are more ...

Archipelago
An archipelago ( ), sometimes called an island group or island chain, is a chain, cluster, or collection of islands. An archipelago may be in an ocean, a sea, or a smaller body of water. Example archipelagos include the Aegean Islands (the origin of the term), the Canadian Arctic Archipelago, the Stockholm Archipelago, the Malay Archipelago (which includes the Indonesian and Philippine Archipelagos), the Lucayan (Bahamian) Archipelago, the Japanese archipelago, and the Hawaiian Archipelago. Etymology The word ''archipelago'' is derived from the Italian ''arcipelago'', used as a proper name for the Aegean Sea, itself perhaps a deformation of the Greek Αιγαίον Πέλαγος. Later, usage shifted to refer to the Aegean Islands (since the sea has a large number of islands). The erudite paretymology, deriving the word from Ancient Greek ἄρχι-(''arkhi-'', "chief") and πέλαγος (''pélagos'', "sea"), proposed by Buondelmonti, can still be found. Geograph ...
