Do sorted or unsorted materials have a higher porosity?
Unsorted materials generally have higher porosity compared to sorted materials. In unsorted materials, particles of varying sizes create more space between them, leading to higher porosity. In contrast, sorted materials have more uniform particle sizes, resulting in less pore space and lower porosity.
What are unsorted deposits?
Unsorted deposits refer to sedimentary deposits that have not been sorted or arranged by size or weight. This means that the particles or materials within the deposit have not undergone any sorting process based on their characteristics, such as size, shape, or density. Examples of unsorted deposits include moraines left by glaciers or alluvial fan deposits.
What is a glacial till?
Glacial till is a type of sediment deposited by glaciers through the process of erosion and transportation. It is a mixture of different sized particles, ranging from clay to boulders, that is left behind as the glacier melts. Glacial till is an unsorted and unstratified deposit.
How are till and outwash different?
Basically till is unsorted and outwash is sorted. Outwash is sorted by the melt water streams, which have the ability to smooth rocks and pebbles. The till is carried by the glacier which means that all sorts of rocks and boulders can be carried with the ice, creating sharp surfaces on the rocks.
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.

What is a glacier deposit that is sorted into layers based on the size of the rock material?
A stratified drift
Do kettle lakes contain sorted or unsorted sediments?
sorted
What are unsorted deposits?

Is a moraine sorted or unsorted?
A moraine is unsorted. Plucking and abrasion by glaciers do not discriminate in size of material debris. It might grind rock matter into what is called "rock flour" and this may be visible at the snout of a glacier, but this and other debris of any size will be be deposited as unsorted till in the form of an end moraine (terminal moraine). A moraine between 2 glaciers is a medial moraine, a moraine along side the glacier is a lateral moraine. Sometimes till can contain glacial erratics... that is, material that came from very far away and does not fit with other materials in the till deposit. Glaciers act as a conveyor belt depending on budget, and material moves with the plasticity of the ice. I hope this helps a little bit.

What well-sorted sediment results from glacerial erosion?
Glacial erosion typically produces well-sorted sediment known as glacial till. This sediment is composed of a wide range of particle sizes, from clay to boulders, due to the mixing and transport by the glacier. Glacial till is often unsorted and can be deposited directly by the glacier or as moraines when the glacier retreats.
What is the define to the word stratified drift?
Larger rocks deposited closer to the glacier. The rocks form a sorted deposit
How are till and outwash different?

What is the difference between sediments in the outwash and sediments in the moraines?
Sediments in outwash are typically well-sorted and composed of sand and gravel, deposited by meltwater streams flowing from glaciers. In contrast, sediments in moraines are unsorted and contain a mix of various sizes of rocks, debris, and till that has been directly deposited by the glacier. Outwash sediments are usually sorted by size and shape, while moraine sediments are unsorted and show a wider range of material types.
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.
Describe the various types of glacial moraines?
there is glacial drift and that is the act of rock material carried and deposited by glaciers. there is till which is the act of unsorted rock material that is deposited directly by a melting glacier and there is stratified drift which is the result of a glacial deposit that has been sorted and layered by action of streams or meltwater
