Away from land and more probably were caused by subsidence; the old river-channels known to exist below sea-level, as well as the former land connexion with New Guinea, seem to point to the conditions assumed in Darwin's well-known subsidence theory, and any facts that appear to be inconsistent with the theory of a steady and prolonged subsidence are explainable by the assumption of a slight upheaval.
The Cretaceous period was initiated by the subsidence of a large area to the south of the Gulf of Carpentaria, whereby a Lower Cretaceous sea spread southward, across western Queensland, western New South Wales and the north-eastern districts of South Australia.
A theory of a still continuing subsidence of the islands was formed by Kurz in 1866 and confirmed by Oldham in 1884.
Similarly, the subsidence of malaria during cold weather and its seasonal prevalence find an adequate explanation in the conditions governing insect life.
The autumnal subsidence of the river was followed by shallow ploughing performed by oxen yoked to clumsy wooden ploughs, the clods being afterwards levelled with wooden hoes by hand.
These were at one time more numerous than at the present day; earthquakes and subsidence of foundations have brought many of them down, the latest to fall being the great tower of San Marco itself, which collapsed on July 14th, 1902.
Some of the more viscous crude oils obtained in the United States are employed as lubricants under the name of " natural oils," either without any treatment or after clarification by subsidence and filtration through animal charcoal.
On his return from exile, after the subsidence of the Tatar deluge, he found his kingdom in ashes; and his two great remedies, wholesale immigration and castle-building, only sowed the seeds of fresh disasters.
Where each floor is timbered by itself with light timbers, as is the practice on the continent of Europe, the consolidation of the rock-filling under pressure gives rise to considerable subsidence of the unmined ore, which has frequently settled 20 ft.
An interesting local phenomenon is that of lake Tequesquiten, which was formed by the subsidence of a large area of ground about the middle of the 19th century, carrying with it an old town of the same name.
Tanganyika has been formed by the subsidence of a long narrow tract of country relatively to the surrounding plateaus, which fall to the lake in abrupt cliffs, some thousands of feet high in places.
The important part played by the residual air in the globe had also been deduced by Osborne Reynolds from observing that on turning off the light, the vanes came to rest very much sooner than the friction of the pivot alone would account for; in fact, the rapid subsidence is an illustration of Maxwell's great theoretical discovery that viscosity in a gas (as also diffusion both of heat and of the gas itself) is sensibly independent of the density.
The Strait of Dover, the Dardanelles and Bosporus; (3) by overflowing through the subsidence of the land, as in the straits of Bering, Torres and Formosa.
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.
With careful packing it is estimated that the surface subsidence will not exceed 40% of the thickness of the seam removed, and will usually be considerably less.
Back of the islands are the quiet waters of lagoons, and at the mouths of rivers are several shallow bays indenting the mainland; these bays were formed by only a slight subsidence of the land and the rivers are filling them with deposits of silt.
Ansgar preached in Denmark from 826 to 861, but it was not till after the subsidence of the Viking raids that Adaldag, archbishop of Hamburg, could open a new and successful mission, which resulted in the erection of the bishoprics of Schleswig, Ribe and Aarhus (c. 948), though the real conversion of Denmark must be dated from the baptism of King Harold Bluetooth (960).
The existence of ancient lacustrine beaches, upheaved between the two basins by volcanic agencies or left dry by some enlargement of the San Juan outfall, and a consequent subsidence of the water-level, seems to indicate that the lakes were formerly united.
It does not, however, form a delta proportionate to the volume of its water, owing to a strong sea current flowing northwards close to the shore, to the sudden sinking of the sea to a great depth immediately off the mouth of the river, and possibly also to the permanent subsidence of the Italian coast from the Tiber .mouth southwards to Terracina.
After the subsidence came another period of uplift, possibly still in progress.
The legend may be a greatly exaggerated version of some actual subsidence of inhabited land.
There resulted a widespread and violent though ephemeral controversy, after the subsidence of which he published a Lecture on Tradition, which passed through several editions, and a volume on The Thirty-nine Articles of the Church of England.
This cutting off was caused largely by subsidence, though partly by marine action.
At the time of the last great subsidence, in glacial times, an arm of the sea extended across Sweden, submerging a great part of the littoral up to the Gulf of Bothnia, and including the Plies period the this of themnorthe and Baltic were s fg ficiently salt for oysters to flourish.
Then followed a subsidence, which not only re-established communication through the Danish channels, but allowed the Baltic to become sufficiently salt for such forms as Cardium edule and Littorina littorea.
When this bar is gradually increased by storms, tides, or currents, or there is a subsidence of the waters, so that it reaches to the surface, that which was at first but an inclination in the shore in which a thought was harbored becomes an individual lake, cut off from the ocean, wherein the thought secures its own conditions--changes, perhaps, from salt to fresh, becomes a sweet sea, dead sea, or a marsh.
