How is outwash formed
WebTerraces of pitted outwash were formed in the same manner as ordinary outwash terraces, that is, by change in the grade and the load of the streams so that they eroded what they had formerly deposited. Decrease in load is a normal consequence of recession of the ice margin and was accompanied by a decrease of the stream grade. WebGlacial and proglacial lakes are found in a variety of environments and in considerable numbers. Erosional lake basins have already been mentioned, but many lakes are formed as streams are dammed by the ice itself, by glacial deposits, or by a combination of these factors.
