The Appalachian belt includes, with the ranges enumerated above, the plateaus sloping southward to the Atlantic Ocean in New England, and south-eastward to the border of the coastal plain through the central and southern Atlantic states; and on the north-west, the Allegheny and Cumberland plateaus declining toward the Great Lakes and the interior plains.
The Mediterranean Sea, the best-known member of the intercontinental class, is separated from the Atlantic Ocean by a ridge running from Cape Spartel to Cape Trafalgar on which the greatest depth is only 175 fathoms. The depth increases so rapidly towards the east that soundings exceeding 500 fathoms occur off Gibraltar.
After sitting a long time listening to the long stories of some sailors who had just come from a plum-pudding voyage, as they called it (that is, a short whaling-voyage in a schooner or brig, confined to the north of the line, in the Atlantic Ocean only); after listening to these plum-puddingers till nearly eleven o'clock, I went up stairs to go to bed, feeling quite sure by this time Queequeg must certainly have brought his Ramadan to a termination.
Of which it is drained south-eastward into the Atlantic Ocean principally by the Merrimac in the S., the Saco and the headwaters of the Merrimac in the White Mountain region, and the Androscoggin in the N.
The Atlantic Ocean consists of two characteristic divisions, the geographical equator forming a fairly satisfactory line of division into North and South Atlantic. The North Atlantic, by far the best-known of the main divisions of the hydrosphere, is remarkable for the immense length of its coast-line and for the large number of enclosed seas connected with it, including on the western side the Caribbean Sea and Gulf of Mexico, the Gulf of St Lawrence and Hudson Bay, and on the eastern side the Mediterranean and Black Sea, the North Sea and the Baltic. The North Atlantic is connected with the Arctic Basin by four main channels: (1) Hudson Strait, about 60 m.
Some Finnish geologists - Sederholm for one - consider it probable that during the Glacial period an Arctic sea (Yoldia sea) covered all southern Finland and also Scania (Sickle) in Sweden, thus connecting the Atlantic Ocean with the Baltic and the White Sea by a broad channel; but no fossils from that sea have been found anywhere in Finland.
There are no mountains between the Atlantic Ocean and the St. Lawrence river.
At night on the Atlantic Ocean indicates the existence of a fine ship.
In a middle section of the system, from the Hudson river in southern New York to the James river in southern Virginia, the crystalline belt is narrowed, as if by the depression of its south-eastern part beneath the Atlantic Ocean or beneath the strata of the Atlantic coastal plain which now represents the ocean; but the stratified belt is here broadly developed in a remarkable series of ridges and valleys determined by the action of erosion on the many alternations of strong and weak folded strata; and the plateau assumes full strength southward from the monochinal Mohawk valley which separates it from the Adirondacks.
The south-east trade-wind blows obliquely across the Atlantic Ocean until it reaches Brazil.
