Eurth, also known as Earth (Anglish), Alemi (Oharic), or Aerta (Alemannisch), is the fourth planet from the San. It is the only heavenly body in the cosmos known to accommodate life. There are eight million types of animals and plants in the Wurld. Eight million different solutions to staying alive. Scientific analysis and radiometric determination have concluded that Eurth developed over 4 billion years ago. The Eurth rotates around the San in 365 and ¼ days, a period commonly accepted as Eurth year. The seasons are formed by the inclination of the rotational axis in the direction of the orbital surface.

The Mun is an astronomical body that orbits planet Eurth. It is Eurth's only stable natural satellite. The gravitational relation between Eurth and the Mun has many effects: it causes oceanic tides, stabilisation of the planetary axis, and gradual reduction of Eurth's spin. Eurth is the most solid planet in the Sanar System, and the largest of the Eurrestrial planets.

The world contains a large variety of nations where the people speak many languages, such as Anglish, Laimiaic, Fragran, Adapton Aromance, Suverin, Oharic, and Iverican. They also speak thousands of other languages. According to the latest census data, the Eurth is home to about 5 billion human beings.

Etymology

The current Anglish word Eurth evolved from an earlier variant of Early Anglish or Old Alemmanisch. The earliest sources mention Erda, Eorðe or Jörð as a translation of Gaia in Occidental Arhoman, and Erta or Eltus in 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 "world".

Geography

Continents

Eurth has an approximate total land area of 131,750,000 km² (50,870,000 sq mi). 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.

Map of the Continents		Continent	Approx. total area
Alharu Antargis Argis Aurelia Europa Marenesia Thalassa Adisi Ocean Adlantic Ocean Argic Ocean Oriental Ocean		Alharu	32,400,000 km2 (12,500,000 sq mi)
		Antargis	17,800,000 km2 (6,900,000 sq mi)
		Argis	17,200,000 km2 (6,600,000 sq mi)
		Aurelia	13,500,000 km2 (5,200,000 sq mi)
		Europa	40,500,000 km2 (15,600,000 sq mi)
		Marenesia	6,500,000 km2 (2,500,000 sq mi)
		Thalassa	3,850,000 km2 (1,490,000 sq mi)

• Alharu means "hot" in 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 Proto-Europan. It is the northernmost continent. Many states here are inspired by Europa and are populated by Aroman or Buranian cultures and ethnicities.
• Aurelia means "golden" in 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 means "land of the father" in Proto-Europan. It is the northeastern continent. Many states here are inspired by 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 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 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

Main article: List of bodies of water on Eurth

Eurth is a blue planet. The presence of water on its surface is unique in the Sanar system. The main bodies of water in the hydrosphere are the oceans. Ancient Aroma describes the existence of 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

WIP

• Explain lithosphere.
  • The lithosphere is a geologic term for the solid part of the Eurth. This includes the crust and upper mantle.
  • 19 tectonic plates that make up the surface of the Eurth. Their motion is studied in the field of plate tectonics.
  • The plates are around 100 km (62 mi) thick
• Which is the oldest plate?
  • Many tectonic plates have existed and disappeared.
  • There are two main types: oceanic crust and continental crust.
• Where are the oldest rocks? Explain subduction.
  • Subduction is the process where Eurth's crustal plates collide. When two plates collide, one plate is either drawn down or overridden by another.
• List the major tectonic plates from largest to smallest.

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. The 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).

WIP

• The biggest desert. The Paran desert in central Alharu is the largest desert on Eurth.

History

Main article: Timeline of major events on Eurth

Eurth map for children

Eurth is the home-world 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. This region includes such nations as Jilderen, Cabarria, Afropa, Bhalman and Dragonryders. 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, and gradually diverged into new species by around 500,000 years ago, most notably Europithecus saharensis which adapted to live in a savannah-like climate of that time in Sa Hara.

The history of Eurth has always been at the mercy of its geography. Mountains climb and crumble in the cycle of creation and corrosion. Fertile valleys become barren deserts. Rivers flow and flood, or divert and dry up. Eumanity has learned to defeat these obstacles. People level mountains, terrace slopes with plants and irrigate the deserts of Amutia or Alharu. Technology has allowed the construction of sailing fortresses to cross the sea, or giant metal birds to climb the sky. But a single hurricane can destroy in one minute a city that took centuries to construct; one iceberg can sink the sailing city and send a thousand travellers sinking to the bottom of the Adlantic Ocean. When rains run too rare, then colossal cities are covered under the sands, as in once-mighty Memopotamia. When it falls too furiously, then trees strangle societies, as in Azania. Generations of peoples establish a growing dominance over the Eurth, but their final fate is to become fossils under the fields.

Sovereignty disputes

The Eurth edition of Risk game can be used to simulate conflicts.

• Bouenezenn island: Bouenezenn island is divided among the Aurivizht state of Bouenezenn, and the Ebrarian State of Insmerda, both of which claim full ownership over the island.
• Ceris: This island in the Adlantic Ocean is divided among several warring factions.
• Cristina: The city of Cristina is regarded by the Mantellan government as its third constituent entity.
• Deltannia until 1959 was considered a puppet state of Volsci.
• Faramount: Government-in-exile: the People's Republic of Faramount.
• Hexanesa: A breakaway state that is unrecognized by Tagmatium.
• 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.
• Rohini and Burkini have both been described as satellite states of Orioni.

Sanar System

San

The San and its planets

Around 650 BCE, most people believed the Eurth was flat with a sky hanging above it. It wasn't until Classical philosopher Proximander (c. 620 – c. 550 BCE) came along that people began to see that the sky was surrounding us. Later, Aroman philosophers hypothesised that the San, Mun, planets and stars revolved around the Eurth. Humanity held this Eurth-centric view of the universe until the Post-Classical Era. This is when Victor Bronzicus (1464–1523) theorised that the San was really at the centre, with the Eurth, stars and planets revolving around it. Eventually, the scientific establishment accepted his argument. By the early 20th Century, astrophysicists discovered our galaxy to be part of an immeasurably larger cosmic design than what previously thought. Eurth is a mere dust cloud in a universe of galaxies. Then came Hana Sitayini (1897–1966), whose work showed a curved universe. Prior to that, people believed it was flat. She posited that its wavy surface even collected mass so dense as to create canyons, later known as black holes. This leads us to the present-day recognition of a gradually expanding universe, whose extraordinary origin shaped the life we know today.

Mun

Photograph of the Mun

The Mun is a relatively large, terrestrial, planet-like natural satellite. The gravitational attraction between Eurth and its moon causes the ocean's tides. Some scientists believe the Mun may have dramatically affected the development of life by moderating the planet's climate. The name of the Mun varies in different cultures, being known variously as Muna in Arhoman, Mun in Anglish, Ayibi in Oharic. As of 2020, there were 704 operational, human-made satellites orbiting the planet. There are also inoperative satellites and over 9,000 pieces of tracked space debris. Eurth's largest artificial satellite is the EOS Space Station.
