The map depicts the main landmarks of the time, and figures such as the legendary Prester John in Africa, the Great Khan in China, "Xilam" and Sumatra, and the design of a three-masted European ship in the Indian Ocean, something which had not occurred, suggesting that a sea-lane was a possibility.
During the Lower Paleozoic Era, Proto-Europe acquired a large piece of crust, known as East Avalonia, that would eventually become northwestern Scotland. [1] Avalonia itself would eventually separate into the eastern coastal region of North America, divided by the Atlantic Ocean, from southern Ireland, England, Wales, Belgium, and the Netherlands.
The geology of Europe is varied and complex, and gives rise to the wide variety of landscapes found across the continent, from the Scottish Highlands to the rolling plains of Hungary. Europe's most significant feature is the dichotomy between highland and mountainous Southern Europe and a vast, partially underwater, northern plain ranging from ...
In medieval T and O maps, Asia makes for half the world's landmass, with Africa and Europe accounting for a quarter each. With the High Middle Ages, Southwest and Central Asia receive better resolution in Muslim geography, and the 11th century map by Mahmud al-Kashgari is the first world map drawn from a Central Asian point of view.
The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (a scientific branch of geology that aims to determine the age of rocks).
Because defining a GSSP depends on finding well-preserved geologic sections and identifying key events, this task becomes more difficult as one goes farther back in time. Before 630 million years ago, boundaries on the geologic timescale are defined simply by reference to fixed dates, known as "Global Standard Stratigraphic Ages" (GSSAs).
The phantom islands of Frisland and Brasil in the North Atlantic persist in the maps of the period even though they were in waters readily accessed by European sailors. He does show a Strait of Anian between Asia and the Americas as well as NW and NE passages to the spice islands of the East: this he justifies on his studies of the ancient ...
Tectonic map of southern Europe and the Middle East, showing tectonic structures of the western Alpide mountain belt. The Alpine orogeny or Alpide orogeny [dubious – discuss] is an orogenic phase in the Late Mesozoic [1] (Eoalpine) and the current Cenozoic that has formed the mountain ranges of the Alpide belt.
