Yes, sediments can be sorted by mass movement processes like landslides and rockfalls. These events can segregate sediments based on their size and density, with larger and heavier particles typically settling closer to the source of the movement and finer particles being carried further away.
What else can I help you with?
Sediments with a mixture of sizes are known as?
The sediments with a mixture of sizes are known as poorly sorted sediments. This means that the particles have not been sorted by size and can range from fine to coarse within the same sediment deposit.
What type of mass movement occurs when sediments freeze and thaw?
Frost heaving is the mass movement that occurs when sediments freeze and thaw. During freezing, water in the sediments expands as it turns to ice, pushing particles upwards. When the ice thaws, the sediments settle back down, causing the surface to move vertically over time.
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.
One trigger of mass movement is the pores in sediments filling with what?
Water and sediment are common substances that can fill the pores in sediments and act as triggers for mass movements. When the pores become saturated with water, it can decrease the strength and stability of the sediment, leading to events like landslides or debris flows.
How does mass movement occur?
creep mass movement occurs where ice wedging takes place.(ice wedging means the ground is freezing and thawing over and over again) As the ground freezes, it expands the water in the soil to push up the sediments. when the ground thaws out all the sediments will fall downslope. Creep is a slow process.

Do kettle lakes contain sorted or unsorted sediments?
sorted
What are large amounts of sediments sliding downhill?
mass movement
Which transport media generally results in the most well-sorted sediments?
Water transport generally results in the most well-sorted sediments, as the sorting of particles based on size occurs more efficiently in water compared to other transport media such as wind or ice. The constant movement and turbulence of water helps to separate particles by size, leading to well-sorted sediments.
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

What form of mass movement occurs when a pasty mix of water and sediments moves downhill?
"mud slide"
Which mass wasting is slow movement of solid particles down?
A slow mass movement of individual sediments is a creep. It happens so slowly that you cannot see it happening and it can go on for years.
Wicth type of mass movement occurs when sediments slowly move downhill because of freezeing and thawing?
creep
How could you identify sediments sorted by water?
Sediments sorted by water typically show distinct layering or sorting based on size and density. Water-sorted sediments often have rounded grains or particles due to the process of abrasion during transport. Additionally, these sediments may display features such as cross-bedding, ripple marks, or graded bedding that indicate water flow direction and energy.
