Parent material that was physically moved and deposited by the glacier itself.
A
glacial till
B
alluvium
C
topography
D
prairie soil
E
physical weathering
Explanation: 

Detailed explanation-1: -Parent material transported by ice is known as glacial till. This parent material is found where glaciers have deposited material, such as in terminal moraines or lateral moraines. Ice itself is a poor sorter of soil particles.

Detailed explanation-2: -Glacial till. This is that part of the glacial drift deposited directly by the ice with little or no transportation by water. It is generally an unstratified, heterogeneous mixture of clay, silt, sand, gravel, and sometimes boulders.

Detailed explanation-3: -Loess. The term loess (meaning “crumbly” in German) is used to describe silt textured eolian material. Loess can be interpreted as an accumulation of wind-blown dust, usually of glacial origin.

Detailed explanation-4: -Glacial Outwash: This material was carried by ice but sorted by water as it was rushing out of the glacier. Small particles that could stay suspended in water, like silts and clays, were washed away. Larger particles, like sands and gravels, were sorted and deposited at the edge of the current glacier.

Detailed explanation-5: -Parent materials that form in place from the weathering of rock in place are called residuum. The major types of rocks that weather to form residuum are igneous, sedimentary, and metamorphic.
