In geography, a plain is a land with relatively high relief, as well as flat. Prairies and steppes are types of plains, and the archetype for a plain is often thought of as a grassland, but plains in their natural state may also be covered in shrublands, woodland and forest, or vegetation may be absent in the case of sandy or stony plains in hot deserts. Types of flatlands for which the term is not generally used include those covered entirely and permanently by swamps, marshes, playas, or ice sheets.

Plains occur as lowlands and at the bottoms of valleys but also on plateaus at high elevations. In a valley, a plain is enclosed on two sides but in other cases a plain may be delineated by a complete or partial ring of hills, by mountains or cliffs. Where a geological region contains more than one plain, they may be connected by a pass (sometime termed a gap). Plains may have been formed from flowing lava, deposited by water, ice or wind, or formed by erosion by these agents from hills and mountains.

Plains in many areas are important for agriculture, because where the soils were deposited as sediments they may be deep and fertile, and the flatness facilitates mechanization of crop production; or because they support grasslands which provide good grazing for livestock.

Types of terrestrial plains

Part of the plain that surrounds Lightning Ridge, New South Wales, Australia
  • Coastal plain, an area of low-lying land adjacent to a sea; the term is used especially where they contrast with hills, mountains or plateaux further inland.
  • Fluvial plains are formed by rivers, and may be one of these overlapping types:
    • Flood plain, adjacent to a stream, river, lake or wetland that experiences occasional or periodic flooding.
    • Alluvial plain, formed over a long period of time by a river depositing sediment on its floodplain or bed which becomes alluvial soil. The difference between a floodplain and an alluvial plain is that the floodplain represents the area experiencing flooding fairly regularly in the present or recently, whereas an alluvial plain includes areas where the floodplain is now and used to be, or areas which only experience flooding a few times a century.
    • Scroll plain, a plain through which a river meanders with a very low gradient.
  • Lacustrine plain, a plain that originally formed in a lacustrine environment, that is, as the bed of a lake.
  • Lava plain, formed by sheets of flowing lava.
  • Glacial plains are formed by the movement of glaciers under the force of gravity:
    • Till plain, a plain of glacial till that forms when a sheet of ice becomes detached from the main body of a glacier and melts in place depositing the sediments it carries. Till plains are composed of unsorted material (till) of all sizes.
    • Sandur (plural sandar), a glacial outwash plain formed of sediments deposited by meltwater at the terminus of a glacier. Sandar consist mainly of stratified (layered and sorted) gravel and sand.

Other types

The term may also be used for flat areas of the ocean floor or for flat areas on moons and planets.

  • Abyssal plain, a flat or very gently sloping area of the deep ocean basin floor.

From BibleWiki

  1. Heb. 'abel (Jdg 11:33), a "grassy plain" or "meadow." Instead of "plains of the vineyards," as in the Authorized Version, the Revised Version has "Abel-cheramim" (q.v.), comp. Jdg 11:22; 2Chr 16:4.
  2. Heb. 'elon (Gen 12:6; 13:18; 14:13; 18:1; Deut 11:30; Jdg 9:6), more correctly "oak," as in the Revised Version; margin, "terebinth."
  3. Heb. bik'ah (Gen 11:2; Neh 6:2; Ezek 3:23; Dan 3:1), properly a valley, as rendered in Isa 40:4, a broad plain between mountains. In Amos 1:5 the margin of Authorized Version has "Bikathaven."
  4. Heb. kikar, "the circle," used only of the Ghor, or the low ground along the Jordan (Gen 13:10-12; 19:17, 25, 28, 29; Deut 34:3; 2 Sam 18:23; 1 Kg 7:46; 2Chr 4:17; Neh 3:22; 12:28), the floor of the valley through which it flows. This name is applied to the Jordan valley as far north as Succoth.
  5. Heb. mishor, "level ground," smooth, grassy table-land (Deut 3:10; 4:43; Josh 13:9, 16, 17, 21; 20:8; Jer 48:21), an expanse of rolling downs without rock or stone. In these passages, with the article prefixed, it denotes the plain in the tribe of Reuben. In 2Chr 26:10 the plain of Judah is meant. Jerusalem is called "the rock of the plain" in Jer 21:13, because the hills on which it is built rise high above the plain.
  6. Heb. 'arabah, the valley from the Sea of Galilee southward to the Dead Sea (the "sea of the plain," 2Kg 14:25; Deut 1:1; 2:8), a distance of about 70 miles. It is called by the modern Arabs the Ghor. This Hebrew name is found in Authorized Version (Josh 18:18), and is uniformly used in the Revised Version. Down through the centre of this plain is a ravine, from 200 to 300 yards wide, and from 50 to 100 feet deep, through which the Jordan flows in a winding course. This ravine is called the "lower plain."

The name Arabah is also applied to the whole Jordan valley from Mount Hermon to the eastern branch of the Red Sea, a distance of about 200 miles, as well as to that portion of the valley which stretches from the Sea of Galilee to the same branch of the Red Sea, i.e., to the Gulf of Akabah about 100 miles in all.

  1. Heb. shephelah, "low ground," "low hill-land," rendered "vale" or "valley" in Authorized Version (Josh 9:1; 10:40; 11:2; 12:8; Jdg 1:9; 1 Kg 10:27). In Authorized Version (1Chr 27:28; 2Chr 26:10) it is also rendered "low country." In Jer 17:26, Obad 1:19, Zech 7:7, "plain." The Revised Version renders it uniformly "low land." When it is preceded by the article, as in Deut 1:7, Josh 11:16; 15:33, Jer 32:44; 33:13, Zech 7:7, "the shephelah," it denotes the plain along the Mediterranean from Joppa to Gaza, "the plain of the Philistines." (See VALLEY.)
