Moghan plain, East Azarbaijan Province, Iran
In geography, a plain is a large area of land with relatively low relief. Plains may be more suitable for farming than plateaus or mountains. Plains are sometimes remnants of much larger features that are now largely eroded, such as mountains or volcanoes.

    A scroll plain occurs where a river meanders across an area with a very low gradient, usually with a fairly continuous discharge. In addition to meanders, scroll plains are also characterised by many oxbow lakes.

    A meander is a bend in a river, also known as an oxbow loop, or simply an oxbow. A stream or river flowing through a wide valley or flat plain will tend to form a meandering stream course as it alternatively erodes and deposits sediments along its course.

    A till plain is an extensive flat 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 carried. A till plain with irregular topography is referred to as a ground moraine.

    Till is an unsorted glacial sediment. Glacial drift is a general term for the coarsely graded and extremely heterogeneous sediments of glacial origin. Glacial till is that part of glacial drift which was deposited directly by the glacier.
