What else can I help you with?
When a glacier stands still the ice within it is?
still flows and carries debris to the end of the glacier
What is A large boulder that is left behind by a glacier and deposited among rocks of a different type is called?
The rock is called a glacial erratic when it is left behind by a glacier, and is of a completely different material composition than the rocks on which it was deposited.
What does the ice do when the glacier stands still?
When a glacier stands still, the ice continues to deform under its own weight due to gravity. This slow movement, called glacial flow, can cause the ice to thicken and flow downstream. Over time, the ice can also melt from the surface and sublimate into the air.
Why do you find large mountains of rock at the end of the glacier?
Large mountains of rock at the end of a glacier, known as moraines, are formed by the accumulation of debris that the glacier has eroded from the landscape as it moves. As glaciers advance and retreat, they carry along rocks, soil, and other materials, depositing them when they melt or lose mass. These formations can provide valuable insights into the glacier's past movement and the geological history of the area. Moraines serve as important indicators of climatic changes and glacial dynamics over time.
What is the ridge at the end of the glacier?
The ridge at the end of a glacier is called a terminal moraine. It forms when debris and sediment that were carried by the glacier accumulate and are deposited at the glacier's snout as it melts and retreats. Terminal moraines can help mark the furthest extent of a glacier's advance.
What are terminal moraine?
Terminal moraines are ridges of glacial debris deposited at the furthest point reached by a glacier. They mark the end of a glacier's advance and can be seen as a line of debris and rocks left behind as the glacier melts and retreats. These moraines are called "terminal" because they are found at the glacier’s terminus.

What is the material called that is deposited by meltwater beyond the end of a glacier?
The material deposited by meltwater beyond the end of a glacier is called glacial outwash or outwash plain. It consists of sediments such as sand, gravel, and boulders that have been carried by the flowing meltwater and deposited as the glacier retreats.
Are glaciers an agent of erosion?
Yes. Look at any glacial (u-shaped) valley and the terminal moraine at the end where the glacier melts.

How do a moraine form?
A moraine forms as a result of glacial activity, specifically through the accumulation of debris that glaciers transport and deposit. As a glacier moves, it erodes the landscape, picking up rocks and sediments, which are then carried along. When the glacier retreats or melts, it leaves behind these materials, creating a ridge or mound known as a moraine. There are different types of moraines, such as terminal moraines at the glacier's end and lateral moraines along its sides.
How do glaciers cause deposition?
Glaciers cause deposition through the process of glacial erosion. As glaciers move, they pick up rocks, sediment, and other debris, which eventually get deposited when the glacier melts or retreats. This deposited material forms landforms like moraines, drumlins, and outwash plains.
What is the lower end of a glacier called?
The area that is melting faster than it is accumulating is the "Zone of Ablation." The very bottom end of a glacier is typically called its "foot."
