On this globe an equatorial and a meridional ocean divide our earth FIG.
M., occupies a position a little to the east of a meridional line bisecting the continent, and south of the 22nd degree, but portions of it stretch upwards to the low-lying country south of the Gulf of Carpentaria.
Russia; the Valdai tablelands, where all the great rivers of Russia take their rise; the broad and gently sloping meridional belt of the Ural Mountains; and lastly the Taimyr, Tunguzka and Verkhoyansk ranges in Siberia, which, notwithstanding their sub-Arctic position, do not reach the snow-line.
To General the west of Kashgar the central depression is limited by physio- the meridional range of Sarikol and the great elevation graphs* of the Pamir, of which the Sarikol is the eastern face.
On the western edge of the Kashgar plains, the political boundary between Russia and China is defined by the meridional range of Sarikol.
Eastwards of this the great Kashgar depression, which includes the Tarim desert, separates Russia from the vast sterile highlands of Tibet; and a continuous series of desert spaces of low elevation, marking the limits of a primeval inland sea from the Sarikol meridional watershed to the Khingan mountains on the western borders of Manchuria, divide her from the northern provinces of China.
A very remarkable meridional range extends for loo m.
It may be said to spring from the head of the Taghdumbash Pamir, where it unites with the great meridional system of Sarikol stretching northwards, and the yet more impressive mountain barrier of Murtagh, the northern base of which separates China from the semi-independent territory of Kanjut.
The Senonian consists of a central facies with Micraster peini; a meridional facies with Ostrea; and a northern facies developed round Tunisia with large forms of Inoceramus and echinoids.
Of granite are chiefly formed the meridional mountains of Shinano.
A deep narrow gorge, the so-called "eastern rift-valley," traverses the middle of the plateau in a meridional direction.
Sphere are necessarily circles; if the cutting plane contains the centre, the section is said to be "meridional," the curve of intersection is a "great circle," and the solid cut off a "hemisphere."
This work was afterwards extended by Struve and General Tenner into a measurement of a meridional arc from the north coast of Norway to Ismail on the Danube (Arc du meridien de 25° 20' entre le Danube et la Mer Glaciale, 2 vols.
The finest examples of this kind are the moraines about Jackson Lake on the basin floor east of the Teton Range (Grand Teton, 13,747 ft.), a superb north-south range which lies close to the meridional boundary line between Wyoming and Idaho.
The general meridional direction of the ranges and valleys determines the direction of the prevailing surface winds, this being, however, subject to many local modifications.
The"meridional ridges which formerly used to be traced here along the main water-partings do not exist in reality, and the country appears on the hypsometrical map in the Atlas de Finlande as a plateau of 350 ft.
In the " first principal section " or " meridional section," and the other at right angles to it, i.e.
The course of the rays in the meridional section is no longer symmetrical to the principal ray of the pencil; and on an intercepting plane there appears, instead of a luminous point, a patch of light, not symmetrical about a point, and often exhibiting a resemblance to a comet having its tail directed towards or away from the axis.
The unsymmetrical form of the meridional pencil - formerly the only one considered - is coma in the narrower sense only; other errors of coma have been treated by A.
Biot, to complete the meridional measurements which had been begun by J.
Directly south are the beginnings of the meridional arteries, the Hab, the Purali and the Hingol, which end in the Arabian Sea, leaving a space of mountainous seaboard (Makran) south of the Panjgur and west of the Hingol, which is watered (so far as it is watered at all) by the long lateral Kej river and several smaller mountain streams. Thus southern Baluchistan comprises four hydrographical sections.
The axis, or backbone, of Pamir formation is the great meridional mountain chain of Sarikol - the ancient Taurus of tradition and history - on which stands the highest peak north of the Himalaya, the Murtagh Ata (25,000 ft.).
Associated with these great valleys are a number of volcanic peaks, the greatest of which occur on a meridional line east of the eastern trough.
Both possess a meridional extension with a broad east and west folded region in the north.
The last phase of vulcanicity took place along the great meridional rifts of East Africa, and though feebly manifested has not entirely passed away.
The Red Sea also occupies a meridional trough.
