These lakes are expanses of brackish waters that spread or Lakes.
She set about wandering the halls once more, pausing to look out of large windows onto expanses of grass.
Polar explorers making sections across the great expanses of water with everfrequently repeated those experiments in deep-sea soundings, increasing accuracy, and in that work the government surveying both William Scoresby and Sir John Ross obtaining notable ships have also been engaged, vast stretches of the Indian and results, though not reaching depths of more than 1200 fathoms. Pacific Oceans having been opened up to knowledge by H.M.SS.
Their experiments show that in similar conditions the evaporation of sea-water amounts to from 70 to 91% of the evaporation of fresh water, a fact of some importance in geophysics on account of the vast expanses of ocean the evaporation from which determines the rainfall and to a large extent the heat-transference in the atmosphere.
Their range in space, including carriage by birds, may be coextensive with the distribution of water, but it is not known what height of temperature or how much chemical adulteration of the water they can sustain, how far they can penetrate underground, nor what are the limits of their activity between the floor and the surface of aquatic expanses, fresh or saline.
Plenty of springs issue on the highlands, and wide expanses of grassy country dotted with trees like an English park are met with.
Low temperatures are prevalent throughout these western regions, whose bleak desolation is unrelieved by the existence of trees or vegetation of any size, and where the wind sweeps unchecked across vast expanses of arid plain.
Straths are broad expanses of low ground between bounding hills and are usually traversed by one main stream and its tributaries - e.g.
In the flood area of the upper Kapuas, of which mention has already been made, there occurs Lake Luar, and there are several lake expanses of a similar character in the basins of the Barito and Kutei rivers.
That city, like Ravenna, originally stood in the midst of a lagoon; and the coast east of it to near Monfalcone, where it meets the mountains, is occupied by similar expanses of water, which are, however, becoming gradually converted into dry land.
They are smooth depressed areas (in the case of the largest, the Shat el Jerid, lying a few feet below the level of the Mediterranean), which for more than half the year are expanses of dried mud covered with a thick incrustation of white or grey salt.
In some valleys there are expanses of sugar-cane, in others cotton, whilst in others vineyards and olive-yards predominate.
Much of the ruggedness and beauty of the mountains is due to the erosive action of many alpine glaciers that once existed on the higher summits, and which have left behind their evidences in valleys and amphitheatres with towering walls, polished rock-expanses, glacial lakes and meadows and tumbling waterfalls.
There are numerous large expanses of level country, the most notable of these being the plains (cameos) of the Tagus valley, and of Aviz or Benavilla, Beja and Ourique, in Alemtejo; the high plateaux (cimas) of Mogadouro in Traz-os-Montes and Ourem between the Tagus and the upper Sorraia; the highly cultivated lowlands (veigas) of Chaves and Valenta do Minho in the extreme north; and the marshy flats (baixas) along the coast of Alemtejo and the southern shore of the lower Tagus.
The general aspect of the district is that of a flat even country, dotted with clusters of bamboos and betelnut trees, and intersected by a perfect network of dark-coloured and sluggish streams. There is not a hill or hillock in the whole district, but it derives a certain picturesque beauty from its wide expanses of cultivation, and the greenness and freshness of the vegetation.
There are ampler expanses of hard saliferous clay (shor) and on the north side of the desert of Lop the surface has been carved and sculptured by the wind into innumerable flat, tabletopped masses (jardangs) with vertical or even overhanging sides, separated from one another by deep-cut, wind-swept gullies, running from north-east to south-west.
Rather the bogs of the plain are intersected by strips of low-lying firm ground, and the central plain consists of these bright green expanses alternating with the brown of the bogs, of which the best known and (with its offshoots) one of the most extensive is the Bog of rAllen in the eastern midlands.
In the north lie Loughs Melvin, close above Donegal Bay, and Gill near Sligo, Lough Gara, draining to the Shannon, and Lough Conn near Ballina (county Mayo), and in the south, the great expanses of Loughs Mask and Corrib, joined by a subterranean channel.
The valleys are wide expanses of arable land, and the hills are for the most part grass-covered and treeless.
Summer sees the lotus (renge) convert wide expanses of lake and river into sheets of white and red blossoms; a comparatively flowerless interval ensues until, in October and November, the chrysanthemum arrives to furnish an excuse for fashionable gatherings.
At some points, notably at Lake Peoria, it broadens into vast expanses resembling lakes.
In the middle ages there were considerable forests in Ireland encompassing broad expanses of upland pastures and marshy meadows.
Besides the sterile and monotonous steppes, valuable only as pasture, and so sparsely populated that it is possible to travel for many hours without encountering any sign of human life except a primitive artesian well or a shepherd's hut, there are wide expanses of fen-country, regularly flooded in spring and autumn.
The surface of Spain is remarkable at once for its striking contrasts and its vast expanses of dreary uniformity.
Gigantic reeds and grasses occupy the low lands near the banks of the great river; expanses of fertile rice-land come next; a little higher up, dotted with villages encircled by groves of bamboos and fruit trees of great size and beauty, the dark forests succeed, covering the interior table-land and mountains.
