Why do some glacial deposition have sorted sediments while others do not?

Glacial sediments that are sorted are due to flowing water in the glacier. Unsorted sediments are those that have thawed out of the ice randomly.

Which transport media generally results in the most well-sorted sediments?
The transport media that generally results in the most well-sorted sediments is wind. Other transport media include rivers, glaciers and landslides.
When all the particles in a sediments are about the same size the sediment is said to be?
well sorted
How could you identify sediments sorted by water?
larger items on the bottom with smaller sediments on top.its because of density i believe..a glacier doesnt sort by size. just random..
What is a glacial till?
glacial till is the stuff deposited from a glacier.
How are glacial drift and till alike How are they different?
Till or glacial till is unsorted glacial sediment. Glacial drift is a general term for the coarsely graded and extremely heterogeneous sediments of glacial origin.Glacial till is that part of glacial drift which was deposited directly by the glacier.Its content may vary from clays to mixtures of clay, sand, gravel and boulders. This material is mostly derived from the subglacial erosion and entrainment by the moving ice of the glaciers of previously available unconsolidated sediments.A glacier is a large persistent body of ice that forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.
Do kettle lakes contain sorted or unsorted sediments?
sorted
Sediments with a mixture of sizes are known as?
poorly sorted sediments
A glacial deposit that is sorted and layered by streams or melt water is called?
a glacial deposit that is sorted and layered by streams or melted water is called
What is the difference between sediments in the outwash and sediments in the moraines?
Sediments that are in outwash are sorted sediments, organized by size, while sediments that are in moraine are unsorted.
What is the brief summary of the section sorting in the Earth space science book?
sorting is the tendency for currents of air or water to separate sediments according to size. sediments that can be sorted is sorted very poorly or somewhat between good and bad sorting. all the grains are rough in the well sorted sediments from the same sized and shape. many different size and shape sediments are sorted in the very poorly sediments category. the sorting of a result of change in the in speed of that agent that is moving the sediments.
How do poorly sorted and well sorted sediments differ?
the well sorted is on the left & the poorly sorted is on the right .. It all depends on the arrangement and size of the rocks
Are graded deposits sorted deposits?
Graded deposits have been sorted by size, usually by deposition from moving water.
What is it called when sediments are layered and sorted by size?
It is called graded bedding.
Which transport media generally results in the most well-sorted sediments?
The transport media that generally results in the most well-sorted sediments is wind. Other transport media include rivers, glaciers and landslides.
What are unsorted sediments?
\sediments that are in a body of water that are not sorted by their type of sediment. for example, if there were cobbles, pebbles, and silt, in a lake, that would be unsorted
When all the particles in a sediments are about the same size the sediment is said to be?
well sorted
What is the difference between poorly sorted and well sorted sediments?
A well sorted soil has particles which are all a similar size, a well graded soil would be classified as poorly graded. Whereas a poorly sorted soil has a wide range of particle sizes and is classified as well graded. On a particle size distribution a well sorted soil gives a steep gradient.
