Wegener speculated — correctly, as it turned out — that the surrounding continents had originally been welded together in a single landmass, which he called Pangea.
Their shells became incorporated into the sediment as more fine mud rained down upon them: mud originated from the erosion of an ancient landmass, which itself was the product of a previous cycle of Earth history.
Exhibits are full of fascinating trivia, including remnants from a box of Grape Nuts Cereal that MacMillan loved, and items from the Crocker Land Expedition - a failed attempt to find a new arctic landmass, which was proven to be merely an optical illusion.
The combination of the gravitational data with that provided by the zircons suggested the presence of a large, arc-shaped, submerged landmass (which the scientists called Mauritia) that extends from Mauritius to India's southwestern coast.
The back of the shirt regretted the separation of Gondwanaland, once the world's southernmost landmass, which split apart during the breaking up of the supercontinent, Pangaea, to form much of today's southern hemisphere.
India's landmass, which forms the northwestern portion of the Indian-Australian Plate, began to drift slowly northward toward the much larger Eurasian Plate several hundred million years ago (after the former broke away from the ancient southern-hemispheric supercontinent known as Gondwana, or Gondwanaland).
As the former landmass, which included the Seychelles, split up and drifted apart, Mauritia split off on its own.
The fragmentation of the landmass which led to the formation of the archipelago of Skyros, and hence the separation from Piperi, had occurred by the early Eemian period [ 52, 53].
The difference in climate between the two zones is caused by the summer monsoon, which blows from the Pacific Ocean bringing warmer temperatures and rain, and the winter monsoon from the Asian landmass, which brings freezing temperatures and heavy snowfalls to areas on the Sea of Japan side.
On one side of the game board they will find marked a landmass from which they will launch their bids to conquer the world.
