Glacial till is the soil deposited by ____
A
wind
B
water
C
gravity
D
glaciers
Explanation: 

Detailed explanation-1: -Deposits directly made by melting of glaciers are called till. The soil carried by the melting water from the frint of a glacier is termed out-wash.

Detailed explanation-2: -Till is a form of glacial drift, which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice.

Detailed explanation-3: -Significant deposits of sand and gravel were produced by deltas formed by glacial streams and in valleys filled by retreating glaciers. Sand also accumulated in snake-like tunnels beneath the ice, in which sand was deposited by flowing subglacial streams; these sinuous deposits of sand are called eskers.

Detailed explanation-4: -Overview. Glaciers erode and transport rock as they flow down slope. Then, when the glaciers start to melt or recede, the sediment is deposited as unsorted glacial till, often in characteristic landforms such as moraines and their associated sedimentary facies.
