OUTWASH PLAINS. The large quantities of water that flowed from the melting ice deposited various kinds of materials, the most important of which is called glacial outwash. Outwash plains made up of outwash deposits are characteristically flat and consist of layers of sand and other fine sediments. till plain is composed of unsorted material (till) of all sizes with much clay, an outwash plain is mainly stratified (layered and sorted) gravel and sand. The till plain has a gently undulating to hilly surface; the outwash is flat or very gently undulating where it is a thin veneer on the underlying till.
The largest plains on dry land are the Great and Central plains in North America, the Amazon and Guyana lowlands in South America, the East European Plain in Europe, the Western Siberian, North China, and Indo-Gangetic plains in Asia, the Sahara and Sudan plains in Africa, and the Central Lowlands in Australia.lains occupy the largest part of the earthâs surface. The basins of the greatest rivers and the largest lakes are located on plains, and in terms of terrain plains are the most suitable areas for human habitation.
