Lighter shades denote countries with a lower ecological footprint per capita and darker shaded for countries with a higher ecological footprint per capita. The total ecological footprint (global hectares affected by humans) is measured as a total of six factors: cropland footprint, grazing footprint, forest footprint, fishing ground footprint ...
The second theory is that the geographical setting and climate of the Carboniferous were unique in Earth's history: the co-occurrence of the position of the continents across the humid equatorial zone, high biological productivity, and the low-lying, water-logged and slowly subsiding sedimentary basins that allowed the thick accumulation of ...
Early world maps cover depictions of the world from the Iron Age to the Age of Discovery and the emergence of modern geography during the early modern period.Old maps provide information about places that were known in past times, as well as the philosophical and cultural basis of the map, which were often much different from modern cartography.
Dicroidium zuberi, an Early Triassic plant from Pangaea (present-day Argentina) The four floristic provinces of the world at the Permian-Carboniferous boundary, 300 million years ago. Pangaea existed as a supercontinent for 160 million years, from its assembly around 335 Ma (Early Carboniferous) to its breakup 175 Ma (Middle Jurassic). [3]
Map of Earth during the Early Permian, around 285 million years ago, showing Central Pangean mountain range at equator. The Central Pangean Mountains were formed during the collision of Euramerica and northern Gondwana as part of the Variscan and Alleghanian orogenies, which began during the Carboniferous approximately 340 million years ago, and complete by the beginning of the Permian around ...

Microstates and island nations are generally represented by single or few pixels approximate to the capital; all territories indicated in the UN listing of territories and regions are exhibited.
Map of the world at the Carboniferous-Permian boundary (~ 300 million years ago) showing Cathaysia (pink) Cathaysia was a microcontinent or a group of terranes that rifted off Gondwana during the Late Paleozoic .
The De Virga world map was made by Albertinus de Virga between 1411 and 1415. Albertin de Virga, a Venetian, is also known for a 1409 map of the Mediterranean, also made in Venice. The world map is circular, drawn on a piece of parchment 69.6 cm × 44 cm (27.4 in × 17.3 in). It consists of the map itself, about 44 cm (17 in) in diameter, and ...
