Why is till considered unsorted?

Till, or glacial till, is considered unsorted because it is composed of a mixture of sediments that vary widely in size, ranging from clay to boulders, without any systematic layering or sorting. This heterogeneous mixture results from the mechanical processes of glacial movement, where glaciers grind and transport materials of different sizes, depositing them indiscriminately as they melt. Unlike sorted sediments, which are typically organized by size due to water or wind sorting mechanisms, till reflects the direct and chaotic deposition from glaciers.
