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 else can I help you with?
How does the slope of the stream affected erosion and deposition?
A steeper slope in a stream increases the velocity of the water, leading to increased erosion of sediment and rocks. This results in greater transportation of material downstream. Conversely, a gentler slope decreases the velocity of the water, causing less erosion and more deposition of sediment.
How can erosion sort sediment?
well, as it is being transported it can be sorted by its size and sediment is often well sorted when it is moved a lot by wind or waves. poorly sorted sediment often results from rapid transportation perhaps by a storm, flash flood, or a volcanic eruption. Sediment left at the edges of glaciers is also poorly sorted.
Which characteristic exists at an erosion deposition interface in a stream where equilibrium occurs?
A characteristic that exists at an erosion-deposition interface in a stream where equilibrium occurs is a balanced sediment load. This means that the stream has enough energy to transport sediment in erosion zones, but also deposits sediment in deposition zones due to reduced energy. This equilibrium results in a stable channel shape and flow pattern.
What is the result of cirque erosion or deposition?
Cirque erosion results in the formation of bowl-shaped depressions at the head of a valley glacier. Deposition can occur when the glacier melts, depositing sediment and creating a small lake called a tarn in the cirque basin.
Is a you shaped valley deposition or erosion?
A U-shaped valley is typically formed by erosion, specifically by the movement of glaciers over time. Glaciers carve out the valley through abrasion and plucking, removing rock and sediment from the valley walls and floor. This process results in the distinctive U-shape of the valley.

How could a rock or a mineral become sediment?
It is through erosion that rocks and minerals become sediments. The weathering and transportation of particles of rock results in the deposition of sediments. We know that wind, water, ice, gravity and some other factors are behind erosion.
How sediment control erosion?
Typically, when the earth's surface is exposed to the impacts of rainfall, there is an increase in the volume and velocity of runoff. This sets off a chain reaction that results in the transport and deposition of sediment, reduced stream capacity, and ultimately increased stream scour and flooding.

What is horizontal erosion?
Horizontal erosion is the process of the removal and transportation of sediment or rock material along a horizontal plane by external forces such as running water, waves, or ice. It tends to occur along riverbanks, coastlines, or glaciers, where the gradual wearing away of material results in the widening or deepening of a landform.
What are results of natural erosion?
Natural erosion can result in the formation of canyons, valleys, and coastlines. It can also lead to the deposition of sediment in new areas, altering the landscape and creating new habitats. However, erosion can also lead to loss of fertile soil, damage to infrastructure, and increased sedimentation in water bodies.
What does erosion look like?
Erosion can appear in various forms, such as gullies, riverbeds, cliffs, and sediment deposits. It often results in the reshaping of the land through the removal of soil and rock by water, wind, or ice over time. Visual signs of erosion include exposed roots, exposed rock layers, and altered landscapes.
