moraines
The accumulation of unsorted rocky debris that is formed by a melting glacier is called a moraine. There are many large moraines throughout the northern parts of North America, Europe, and Asia.
A U-shaped valley is a geological formation formed by the erosive action of a glacier. Ice moving downhill carves out a broad, U-shaped valley with steep sides and a flat bottom. These valleys are characteristic of areas that have been shaped by glacier activity.
Plucking is a glacial erosion process where ice lifts and carries rock fragments. As a glacier moves downhill, these rock fragments can become wedged in crevasses and cracks in the valley floor. Over time, the repeated plucking of these rock fragments by the moving glacier causes the valley to deepen and widen, creating a U-shaped profile.

The tectonic process of divergence can be seen at mid-ocean ridges, such as the Mid-Atlantic Ridge. These are underwater mountain ranges where tectonic plates are moving away from each other, causing new oceanic crust to form through volcanic activity.
Ridges of rock debris that form in front of a glacier are called terminal moraines at the point that the glacier stops moving ahead.
Terminal moraines or terminal
Moraines are formed by the accumulation of unconsolidated rock debris, such as sand, gravel, and boulders, that have been transported and deposited by glaciers. The debris is carried along by the moving glacier and then left behind as the glacier retreats or melts, creating ridges or mounds of sediment.
The place where a glacier stops moving and deposits the rocks and dirt it was carrying is called a terminal moraine. These ridges of debris mark the furthest extent of the glacier's advance.

No. A glacier is a mass of moving snow and ice.
An Alpine Glacier.
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.
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.
Depending on when it was formed, the size and speed it is moving it could be either an Avalanche or Glacier. If it is an incredibly old, slow moving, large, ice mass it is likely a Glacier; however if it is a quickly moving, small (relatively), ice mass it is an Avalanche.
A drumlin is a smooth, elongated mound of glacial till formed by a moving glacier, while an esker is a long, winding ridge of sand and gravel deposited by a meltwater stream flowing in tunnels within or beneath a glacier. Drumlins are typically shaped like hills while eskers are long, narrow ridges.
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.
