Glaciers appear dirty due to the accumulation of debris, such as dust, soil, and rock particles, which can be carried by wind or washed in by meltwater. This debris, along with microorganisms and algae, can darken the ice, reducing its albedo (reflectivity) and causing it to absorb more sunlight. As a result, the glacier melts at an accelerated rate. Additionally, pollutants from human activity can contribute to this "dirty" appearance, affecting glaciers worldwide.
Wind erosion damages land and natural vegetation by removing soil from one place and depositing it in another. It causes soil loss, dryness and deterioration of soil structure. Water erosion is also another factor.
The debris of boulders and coarse material carried by glaciers is known as moraine. Moraines can be found at the edge, sides, and base of glaciers and are deposited as the glacier moves and melts. They can vary in size and shape depending on the glacier's movement and the type of material being transported.
Large particles carried by water include sediment, rocks, debris, and organic matter. These particles can be transported by the flow of water in rivers, streams, and oceans, contributing to erosion and sedimentation processes.
No, sediment of different sized particles left by ice from glaciers is called glacial till. Outwash is sediment deposited by meltwater streams flowing away from a glacier.
The largest particles are carried by the transport medium of glaciers, which can transport rocks, boulders, and sediment over long distances.
Glaciers can carry a wide range of particle sizes, from fine clay-sized particles to large boulders. This range is known as the glacier's "debris load" and includes sediments eroded by the glacier as well as material picked up along its path. The size of particles carried depends on the glacier's size, velocity, and the erosion processes happening at its base.
Weathering breaks down rocks into smaller particles, which are then carried away by soil erosion. This can happen through processes such as water erosion (rainfall washing away particles), wind erosion (blowing particles away), or ice erosion (glaciers transporting particles). The eroded particles are eventually deposited in new locations, contributing to the formation of sedimentary rock or soils.
A load is the term for particles carried by a stream or river.
A graph showing particle size (y-axis) versus distance from glacier source (x-axis) would best represent the range of particle sizes that can be carried by a glacier. The graph would show that larger particles are carried closer to the source of the glacier, while smaller particles are transported further away.

Outwash plains are formed by the deposition of sediments carried by meltwater streams from glaciers. As the glacier retreats, the sediments are deposited in a broad, flat area in front of the glacier. These sediments are typically sorted by size, with larger particles deposited closer to the glacier and smaller particles carried further away.
Stones and sand carried by wind, water, or glaciers are referred to as sediment. This material can be transported in various forms, such as suspended particles in water, grains moved by wind, or larger rocks shifted by glacial movement. Over time, sediments can accumulate and contribute to the formation of sedimentary rock or change landscapes through erosion and deposition processes.
Particles of soil and rock that are carried along in water are called sediment. They can include a range of sizes, from tiny clay particles to larger pebbles and boulders. Sediment transport is an important process in shaping the landscape and can contribute to erosion and deposition in rivers and other water bodies.
