The terms Old and Young Drift are used for all elements of the glacial series even though the meltwater deposits and landforms are not strictly moraines.
Periglacial processes resulted in significant ablation of higher terrain as well as accumulation of sediments in the depressions.
Due to advanced weathering of the sediments near the surface, the soils are more heavily leached ( (brunified, decalcified and/or podsolized).
Very common are wind-formed ablation or accumulation landforms, because during the glacial periods, the wind could easily blow sand and silt away due to the lack of a layer of vegetation.
Young Drift morainic landscapes by contrast have new landforms that are still recognisable as glacial forms.
