The " tetrahedral theory " brought forward by Lowthian Green,' that the form of the earth is a spheroid based on a regular tetrahedron, is more serviceable, because it accounts for three very interesting facts of the terrestrial plan - (1) the antipodal position of continents and ocean basins; (2) the tri angular outline of the continents; and (3) the excess of sea in the southern hemisphere.
If the continuous, unbroken, horizontal extent of land in a continent is termed its trunk,' and the portions cut up by inlets or channels of the sea into islands and peninsulas the limbs, it is possible to compare the continents in an instructive manner.
Murray, " Drainage Areas of the Continents," Scot.
The Ordovician and Silurian systems are widely developed, and it is most probable that, with the exception of the Archean continents of Finland and the S, the sea covered the whole of Russia.
- Lying midway between three continents, Crete was from the earliest period a natural stepping-stone for the passage of early culture from Egypt and the East to mainland Greece.
But the case is quite different if one looks at the two continents as a whole, for improvement in means of communication has brought about strange vicissitudes, and western Europe has asserted her power in middle and eastern Asia.
2 The great plateau of North America, also turning its narrower point towards Bering Strait, naturally suggests the idea that there was a period in the history of our planet when the continents turned their narrow extremities towards the northern pole, as now they turn them towards the southern.
(by the bull Romanus Pontifex, Dec. 20, 1584) ordered the bishops of Italy, Dalmatia and Greece to visit Rome every three years; those of France, Germany, Spain and Portugal, Belgium, Hungary, Bohemia and the British Isles every four years; those from the rest of Europe every five years; and bishops from other continents every ten years.
Notices in Greek authors are collected by P. Paulitschke, Die geographische Erforschung des afrikanischen Continents (Vienna, 1880); the inscriptions were edited and interpreted by G, Maspero, Revue archeol.
Fauna.Japan is an exception to the general rule that continents are richer in fauna than are their neighboring islands.
Here you find articles in the encyclopedia on topics related to places on the world outside the continents of Europe, Asia and Africa and the Americas.
A simple, practical boundary between the three oceans can be obtained by prolonging the meridian of the southern extremity of each of the three southern continents to the Antarctic circle.
Possibly ridges of the sea-bed running southward from the southern continents may yet be discovered which would form more natural boundaries than the meridians.
Where the ocean touches the continents the margin is in places deeply indented by peninsulas and islands marking off portions of the water surface which from all antiquity have been known as " seas."
Kriimmel has calculated the mean depth to be 2010 fathoms (12,060 ft.), while the mean elevation of the surface of the continents above sea-level is only 2300 ft.
The continental shelves include not only the oceanic border of the continents but also great areas of the enclosed seas and particularly of the fringing seas, the origin of which through secular subsidence is often very clearly apparent, as for instance in the North Sea and the tract lying off the mouth of the English Channel.
Complex projects can be carried out on multiple continents through project management tools.
Beside, there were wafted to me evidences of unexplored and uncultivated continents on the other side.
Nay, be a Columbus to whole new continents and worlds within you, opening new channels, not of trade, but of thought.
