The rocks are frozen solid therefore there Sharp edges are not lost
Moraine is the word for rocks and boulders carried along by a glacier and then left behind.
conglomerate
This describes glacial erosion where rocks are frozen into the base of a glacier and then deposited as the glacier melts, leaving behind a trail of rocks.
Sedimentary Rocks
When a glacier melts, the rocks it carried may fall to the ground in a jumble called a moraine. This accumulation of rock, debris, and soil can form a moraine deposit at the edge or base of a glacier.
A moraine is a low ridge of rocks, sand, and soil that is deposited by a glacier as it advances and retreats. It can be found at the edges or terminus of a glacier, marking the furthest extent of the glacier's advance.
Weathering and erosion.
Moraine contain fragmented rocks.
Debris on a glacier can be found scattered on the glacier's surface, within crevasses, or concentrated at the glacier's margins. It can include rocks, sediment, and even man-made objects that have fallen or been carried onto the glacier.
Moraines carried at the bottom of glaciers are called basal or ground moraines. They consist of rocks, soil, and other debris that have been plucked and eroded by the moving glacier. Basal moraines are typically deposited at the glacier's terminus or along its path as the glacier retreats.
The two processes are abrasion and plucking.What processes lead to glacial erosion? Describe them.The two main processes that lead to glacial erosion are plucking and abrasion. Plucking is the process by which a glacier picks off rocks as it blocks over the land. The rock fragments freeze to the bottom of the glacier, gouging and scratching the bedrock as the glacier advances in the process of abrasion.
When a glacier stops moving forward, it deposits the sediment it carried in the form of moraines. Moraines are piles of rocks, debris, and soil that accumulate at the edge or front of a glacier. They can serve as markers of past glacier extent and movement.
