Debris accumulates on the tops of glaciers primarily through processes like weathering, erosion, and deposition. As glaciers move, they grind down underlying rock and soil, picking up materials that can become trapped in or on the ice. Additionally, wind and avalanches can transport debris from surrounding landscapes onto the glacier surface. Over time, this debris can create a layer of sediment known as till, which can be found on the glacier's surface.
Glaciers can have both smooth and rough surfaces. The smoothness or roughness of a glacier's surface depends on factors such as the speed of movement, the presence of debris on the glacier, and the underlying terrain. Fast-moving glaciers tend to have smoother surfaces, while slower-moving glaciers may be rougher due to the accumulation of debris and crevasses.

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.
Glaciers can appear to be white, blue, or even black. They can look white when covered in snow, blue due to ice compression, or black from debris and sediment.
Heaps of earth moved by glaciers are called moraines. These are composed of a mixture of rocks, sediment, and debris that are picked up and transported by glaciers as they move and are then deposited as the glacier melts.

It is valley and continental glaciers they are different because continental glaciers are the largest, and valley glaciers are on the top of mountain peaks.

A medial moraine is formed by deposition. It is a ridge of glacial debris that runs down the center of a glacier where two tributary glaciers merge. The debris is deposited as these glaciers flow and carry rock material with them, which accumulates in the center of the combined glacier.

This is known as glacial till.
As glaciers move, they can pick up loose pieces of rock and debris, which can lead to erosion of the underlying land surface. This process, known as glacial abrasion, can result in the formation of valleys, cirques, and other landforms. Additionally, the debris carried by glaciers can be deposited as moraines when the glacier melts, shaping the landscape further.

A glacier that picks up debris and moves it to other places is called a "lateral moraine." This debris is typically picked up along the sides of the glacier as it moves, and is then deposited in new locations as the glacier advances or retreats.
Glaciers drag immense amount of rock debris along their bottoms. This debris will scar the underlying bedrock, and in mountains, will form U-shaped valleys, as opposed to the more typical V-shape formed from water flow. Rocks dragged and tumbled by glaciers, often show signs of scarring and may also be rounded or smoothed by constant friction with other rocks.
