'''Eurth''', also known as Earth ([[List of Spoken Languages on Eurth|Anglish]]), Alemi ([[Oharic]]), or Aerta ([[List of Spoken Languages on Eurth|Alemannisch]]), is the fourth planet from the [[#San|Sun]]. It is the only heavenly body in the cosmos known to accommodate {{wp|life}}. There are eight million types of animals and plants in the Wurld. Eight million different solutions to staying alive. Scientific analysis and {{wp|radiometric determination}} have concluded that Eurth developed over 4 billion years ago. The Eurth rotates around the Sun in 365 and ¼ days, a period commonly accepted as Eurth {{wp|year}}. The {{wp|seasons}} are formed by the inclination of the {{wp|rotational}} axis in the direction of the orbital surface.
The [[#Mun|Mun]] is an astronomical body that orbits planet Eurth. It is Eurth's only stable {{wp|natural satellite}}. The gravitational relation between Eurth and the Mun has many effects: it causes [[#Oceans|oceanic tides]], stabilisation of the {{wp|planetary axis}}, and gradual reduction of Eurth's spin. Eurth is the most solid planet in the Sunnar System, and the largest of the Eurrestrial planets.
The wurld contains a large variety of nations where the people [[List_of_Spoken_Languages_on_Eurth|speak many languages]], such as Anglish, Laimiaic, Fragran, Adapton Aromance, Suverin, Oharic, and [[Iverica]]n. They also speak thousands of other languages. According to the latest census data, the Eurth is home to about 5 billion {{wp|human}} beings.
__TOC__
== Etymology ==
The current [[List of Spoken Languages on Eurth|Anglish]] word ''Eurth'' evolved from an earlier variant of Early Anglish or Old Alemmanisch. The earliest sources mention ''Erda'', ''Eorðe'' or ''{{wp|Jörð}}'' as a translation of ''Gaia'' in [[List of Spoken Languages on Eurth|Occidental Arhoman]], and ''{{wp|Terra (mythology)|Erta}}'' or ''{{wp|Cel (goddess)|Eltus}}'' in [[List of Spoken Languages on Eurth|East-Arhoman]]. In this context, it refers to the ground or dry soil in contrast to the wet sea. In [[Oharic]] the word ''Alemi'' translates to “wurld.”
In earlier centuries, the name “Europa” was sometimes used interchangeably to refer to the entire planet. However, it only encompasses the northeastern landmass. This was a symptom of old Eurocentric arrogance. As a response to this Eurocentrism, in the 19th century the labels of “[[Old Wurld]]” and “[[New Wurld]]” were introduced.{{efn|OOC. This distinction solves the inconsistency of some older RP stories, published during the years when the community still resided in [[Europa (region)]].}}
== Geography ==
=== Continents ===
Eurth has an approximate total {{wp|land area}} of {{convert|131,750,000|km2|sqmi|abbr=on}}. The remaining 74.17% is covered by water. The land is divided into seven continents. A continent is one of several very large landmasses of the wurld. Identified by convention rather than any strict criteria, we commonly regard up to seven regions as continents. Ordered alphabetically, these continents are: Alharu, Antargis, Argis, Aurelia, Europa, Marenesia and Thalassa. The three continental landmasses of Alharu, Argis and Aurelia are also called the [[New Wurld]]. In contrast, Europa is called the Old Wurld.

* [[Alharu]] means “hot” in [[List_of_Spoken_Languages_on_Eurth|Sahrabic]]. The continent is located between Argis and Aurelia. Much of the Alharun coast was colonised, though parts of it did manage to resist and prosper under indigenous cultures, such as the southern highlands and the massive inland desert. Alharu can be classified as a second-wurld region, with an average GDP per capita of less than $25,000.
* [[Antargis]] means “opposite of Argis.” The continent encompasses the South Pole. Interestingly, a peninsula of the continent is warm enough to be inhabited year-round. The rest of the continent is divided among several powers, with a portion of it being an international zone where any state can build research facilities. Stationing military forces on the continent is prohibited by international treaty.
* [[Argis]] means “white” in [[List_of_Spoken_Languages_on_Eurth|Proto-Europan]]. It is the northernmost continent. Many states here are inspired by Europa and are populated by [[Aroma]]n or [[Burania]]n cultures and ethnicities.
* [[Aurelia]] means “golden” in [[List_of_Spoken_Languages_on_Eurth|Occidental Arhoman]]. It lies south of Alharu. Though technically part of the Alharun continent, Aurelia developed quite differently. The continent is culturally diverse. It is a generally poor area.
* [[Europa (continent)|Europa]] means “land of the father” in [[List_of_Spoken_Languages_on_Eurth|Proto-Europan]]. It is the northeastern continent. Many states here are inspired by {{wp|Afro-Eurasia}} and are populated by cultures and ethnicities of old-wurld origin. Europan nations colonised much of the Eurth. Nowadays, the weakened Europan states are seeking to regain their lost glory.
* [[Marenesia]] means “sea islands” in [[List_of_Spoken_Languages_on_Eurth|East-Arhoman]]. Its islands form the bridge between the old Europa and new wurld. Marenesia is very diverse, both culturally and politically.
* [[Thalassa]] means “sea” in [[List_of_Spoken_Languages_on_Eurth|Occidental Arhoman]]. It is home to many islands that fill the Oriental Ocean. It is home to islander cultures, who sailed their way across the islands from ancient Europa over Marenesia and across to Argis, Alharu and Aurelia.
=== Oceans ===
[[File:Oceans of Eurth.png|200px|thumb|right|Wurld map of oceans with approximate boundaries.]]
{{main|List of bodies of water on Eurth}}
Eurth is a blue planet. The presence of {{wp|water}} on its surface is unique in the [[Sunnar System]]. The main bodies of water in the {{wp|hydrosphere}} are the oceans. Ancient Aroma describes the existence of {{wp|Seven Seas}}. Since the Elevation these are considered to be the seven oceanic bodies of water: [[Adisi Ocean]], [[Adlantic Ocean]] (north and south), [[Antargic Ocean]], [[Argic Ocean]] and [[Oriental Ocean]] (north and south). The deepest underwater location is the $Name Deep of the $Name Trench in the $Select Ocean, with a depth of $Number m ($Number ft). Minor seas include: Azure Sea, Canamo Sea, Dolch Sea, Kosscow Sea, Qingming Sea, Raga Sea, Sunset Sea, Verde Sea, Whanganui Sea, Ygros Sea.
=== Tectonic plates ===
[[File:Tectonic plates of Eurth.png|200px|thumb|right|Eurth's major plates.]]
The lithosphere is the solid part of the Eurth, consisting of the crust and upper mantle. It is made up of 19 tectonic plates that move and interact with each other in a process known as plate tectonics. These plates are around {{convert|125|km|mi}} thick and can be either oceanic or continental in nature. There are many tectonic plates, and their ages can vary. Some plates may have existed for billions of years, while others may have formed more recently. The major tectonic plates, listed from largest to smallest, include the Antarctic Plate, the Thallasan Plate, and the Arcton Plate.
There is no definitive answer whether some tectonic plates are "fast" or "slow" in their movement, as plate movement can vary depending on the specific location and circumstances. However, generally speaking, plates that are moving more quickly may be more likely to experience more frequent earthquakes, while plates that are moving more slowly may experience fewer earthquakes.
Subduction is a process that occurs when two tectonic plates collide, with one plate being either pushed down or overridden by the other. This process can lead to the formation of mountains, volcanoes, and earthquakes.

{{wp|Wladimir Köppen}} introduced his climate classification in the early 20th century. The system forms the basis for climatic regionalisation and glubal modelling. His collaborators and successors later modified it. It is still used by researchers across a widespread range of disciplines.<ref>[https://hal.archives-ouvertes.fr/hal-00298818/document Updated world map of the Köppen-Geiger climate classification] (1 March 2007)</ref> The {{wp|Köppen climate classification}} divides the Eurth into five main climate groups. Each group is further divided by seasonal precipitation and temperature. The five main climate groups are A (tropical), B (dry), C (temperate), D (continental), and E (polar).
* The biggest desert. The Paran desert in central [[Alharu]] is the largest desert on Eurth.
* The warmest place. The highest natural temperature measured at ground level on Eurth is 52.9 °C at $location in $country.
* The coldest climate. The lowest natural temperature measured at ground level on Eurth is −87.9 °C at [[Simon Station]] in [[Antargis]].
Certain {{wp|fauna}} and {{wp|flora}} thrive in certain regions due to the local climate, including temperature, precipitation, and humidity. These factors influence which plants and animals thrive and which do not. Understanding this link between climate and plant and animal life helps scientists and {{wp|Conservation movement|conservationists}} grasp the effects of climate change on ecosystems wurldwide.
[[List of bodies of water on Eurth|Eurth's oceans, seas, and other saltwater bodies]] host {{wp|marine habitats}}, which are home to a range of plant and animal life, including {{wp|coral reef}}s, {{wp|kelp forest}}s, {{wp|seagrass meadow}}s, and more. These biomes are influenced by temperature, {{wp|salinity}}, and nutrient levels, which vary based on location and depth. Coral reefs, for example, are found in shallow, warm waters and are home to {{wp|coral}}, fish, and {{wp|invertebrate}}s. The {{wp|deep sea}} is a cold, high-pressure, and low-light environment that supports adapted plant and animal life such as {{wp|deep-water coral}}s, {{wp|sponge}}s, and {{wp|Bioluminescence|bioluminescent fish}}. Marine biomes are important for providing habitat and contributing to the global climate system, as well as supporting human activities like fishing, tourism, and pharmaceutical production.
== History ==
[[File:Eurth-map-for-children.jpg|200px|thumb|Eurth map for children.]]
{{main|History of Eurth}}
Eurth is the home-wurld of Eumanity, the only known intelligent life in the Euniverse. The earliest eumanoids were the ''Europithecus afropensis''. It appeared about two million years ago and, in several early migrations, it spread throughout southwestern [[Europa (continent)|Europa]]. This region includes such nations as [[Yuropa]], [[Wajoka]], [[Noble Nykia]], [[Cabarria]], and [[Afropa]]. It was likely the first euman species to live in a hunter-gatherer society and to control fire. An adaptive and successful species, ''Europithecus afropensis'' persisted for more than a million years. They gradually diverged into new species by around 500,000 years ago. Most notable was the ''Europithecus saharensis'', which adapted to live in a savannah-like climate of that time in [[Abantium]].
The history of Eurth has always been at the mercy of its [[#Geography|geography]]. Mountains rise and fall in a cycle of creation and corrosion. Verdant valleys become dry deserts. Rivers flow and flood, or divert and dry up. With time, Eumanity learned to defeat these obstacles. People began to level mountains, terraced slopes with plants, and irrigated the deserts of [[Amutia]] or [[Alharu]]. Technology allowed the construction of ships to cross the seas, or giant metal birds to climb the skies. But one iceberg can sink the ship, sending a thousand travellers to the bottom of the [[Adlantic Ocean]]. And a single hurricane can destroy in one minute a city that took centuries to construct. When rains run too rare, then colossal cities are covered under the sands, as in once-mighty [[Memopotamia]]. Or when rain falls too generously, then trees grow to strangle societies, as in [[Azania (region)|Azania]]. Generations of peoples establish a growing dominance over the Eurth, but their final fate is to become fossils under the fields.
== Politics ==
=== Countries ===
{{further|List of countries on Eurth by area|Time zones of Eurth}}
This is a list of countries and {{wp|dependent_territory|dependent territories}} on Eurth, capital city, {{wp|population}}, continent, and government type. The common consensus is that there are {{PAGESINCATEGORY:Countries (Eurth)}} countries on Eurth. Except for [[Antargis]], every land area either belongs to or is claimed by one country or another. The list includes {{wp|sovereign_state|sovereign states}}, inhabited {{wp|dependent_territory|dependent territories}} and, in some cases, constituent countries of sovereign states. The population figures do not reflect the practice of countries that report significantly different populations of citizens domestically and overall.
Government type distinguishes between: {{legend2|pink|border=1px solid|Monarchy}} {{legend2|#b3ccff|border=1px solid|Republic}} {{legend2|lightyellow|border=1px solid|Other}}

* [[Bouenezenn island]]: Bouenezenn island is divided among the Aurivizht state of {{flag|Bouenezenn}}, and the Ebrarian State of {{flag|Insmerda}}, both of which claim full ownership over the island.
* {{flag|Burkini}} and {{flag|Rohini}} have both been described as {{wp|satellite state}}s of [[Orioni]].
* [[Ceris]]: This island in the [[Adlantic Ocean]] is divided among several warring factions of the [[Sentist War]].<ref>[https://www.europans.com/topic/5566-doom-of-ceris/ Doom of Ceris] (31 October 2019)</ref>
* {{flag|Cristina}}: The city of Cristina is regarded by the [[Mantella]]n government as its third constituent entity.
* {{flag|Deltannia}} until 1959 was considered a {{wp|puppet state}} of [[Volsci]].
* {{flag|Faramount}}: {{wp|Government-in-exile}}: the [[People's Republic of Faramount]].
* {{flag|Hexanesa}}: A breakaway state that is unrecognized by [[Tagmatium]].
* {{flag|Mauridiviah}}: Several Madrian groups, the most famous of which being [[Triunforoh Triunfante]], claim legitimate sovereignty over Mauridiviah, but they are not recognized by any nation.
* {{flag|Kaseka}}: Although officially recognised as part of Seylos by [[Great Xio]], the nation has made numerous attempts to coerce the city state and [[Seylos]] into returning it back to the Kingdom of Khao within the Xiohane. Great Xio has also not yet recognised Kaseka as part of the North Adlantic Union.
* {{flag|Sentist State}}: No nation officially recognises it exist, despite its de-facto control over Yosmein, Ashein, and Dopraystein.

== Sunnar System ==
{{main article|Sunnar System}}
The Sunnar System is a collection of orbiting celestial bodies that are gravitionally bound to the Sun. The Sunnar System began its formation {{wp|Formation and evolution of the Solar System|4.6 Billion years ago}} as a result of the gravitational collapse of a large interstellar {{wp|molecular cloud}}. The Sunnar System possesses numerous bodies, the largest beside the Sun being [[Sunnar System|Satre]] having a mass over 480 times that of Eurth.
There are 12 to 14 planets in the Sunnar System, with the status of [[Sunnar System|Paidios]] and [[Sunnar System|Pluta]] as either {{wp|planet|major planets}} or {{wp|Dwarf planet|minor planets}} disputed within the scientific community<ref name='space-contest'>[https://www.europans.com/topic/6481-sanar-system-2021-december-contest/ Sanar System 2021 December Contest] (3 December 2021)</ref>.
=== Sun ===
ㅤ''Main article: {{wp|Sun}}''
[[File:Sunnar System Diagram.png|200px|thumb|right|The Sun and its planets.<ref name='space-contest'>[https://www.europans.com/topic/6481-sanar-system-2021-december-contest/ Sanar System 2021 December Contest] (3 December 2021)</ref>]]
The sun is the Sunnar system’s singular star, with its mass accounting for over 99% of that of the Sunnar system. Due to its massive size the core of the sun is hot and dense enough to sustain nuclear fusion, releasing enormous quantities of energy that is radiated out into space heating up the planets and other celestrial bodies in proximity. It is due to the sun that life exists on Eurth.
=== Planets ===
The planets of the Sunnar System are classified either as the Sunward planets and the Sunway planets, or organised into three groups: inner planets, middle planets, and outer planets. The distinction between the two classifications comes down to whether the planets of Paidios and Pluta are either major planets or {{wp|Dwarf planet|dwarf planets}} within an astronomical community. Most of the scientific community acknowledge Paidios and Pluta as planets in their own right, as their local orbits have been largely cleared of asteroids, though the Dust Belt they are a part of remains. Thus, the 3 groups planetary model is used the most in scientific literature.
==== Inner planets ====
The 7 inner planets orbit the region from the Sun up to the {{wp|Asteroid Belt}}. These planets orbit relatively close to the Sun and are rocky in composition made up of silicate mantles and metal cores. The asteroid belt occupies the orbit between Petrus and Andreus and Satre.<ref name='space-contest'/>. The sunward planets definition also covers the same planets.
* [[Sunnar System|Hyperion]] is the closest planet to the Sun.
* [[Sunnar System|Balder]] and its moon [[Nanna (moon)|Nanna]].
* Eurth and the Moon.
* [[Sunnar System|Laran]]
* [[Sunnar System|Maraz]]
* [[Sunnar System|Pertrus and Andreus]], and their co-orbiting moon [[Sunnar System|Paulus]].
==== Middle planets ====
[[File:Thousandau1 space probe.jpg|200px|thumb|In the 1980s, the {{wp|TAU (spacecraft)|''TAU'' spacecraft}} was launched to explore the Middle and Outer planets.]]
The four middle planets orbit the Sunnar region from the {{wp|Asteroid Belt}} to the [[Sunnar System|Dust Belt]]. The dust belt occupies the orbit between [[Thanatos (planet)|Thanatos]] and [[Paidios (planet)|Paidios]]. The dust belt is a large circle of dust similar to the asteroid belt, consisting mostly of icy objects.<ref name='space-contest'/>. The Sunway definition also include Vanth with the middle planets.
* [[Sunnar System|Satre]], known since ancient times due to its expansive rings, and its moon [[Sunnar System|Albus]]
* [[Sunnar System|Diaphres]] and its moons [[Sunnar System|Apollo]], [[Sunnar System|Nortia]], [[Sunnar System|Maris]], and [[Sunnar System|Artemis]].
* [[Sunnar System|Ether]] and its moon [[Sunnar System|Thalassa]].

The [[Mun]] is a relatively large, terrestrial, planet-like {{wp|natural satellite}}. The gravitational attraction between Eurth and its moon causes the ocean's {{wp|Tide|tides}}. Some scientists believe the Moon may have dramatically affected the development of life by moderating the planet's {{wp|Climate|climate}}. The name of the Moon varies in different cultures, being known variously as ''Muna'' in [[List_of_Spoken_Languages_on_Eurth|Arhoman]], ''Moon'' in [[List_of_Spoken_Languages_on_Eurth|Anglish]], ''Ayibi'' in [[List_of_Spoken_Languages_on_Eurth|Oharic]].
