An extensive pile of till (loose debris & rocks) called an end moraine can build up at the front of the glacier and is typically crescent shaped. Two kinds of end moraines are recognized: terminal and recessional moraines. A terminal moraine is the ridge of till that marks the farthest advance of the glacier before it started to recede. A recessional moraine is one that develops at the front of the receding glacier; a series of recessional moraines mark the path of a retreating glacier.

What is the maraine called that marks the farthest advance of a glacier?
A terminal moraine marks the farthest advance of a glacier.Locally, we have some terminal moraines of hundreds of thousands of years old, and ranging down to about 18 000 years.
What does a terminal moraine mark?
A terminal moraine marks the furthest extent of a glacier's advance. It is a ridge of unsorted glacial debris that accumulates at the terminus of the glacier as it melts and retreats.
Is terminal moraines a glacial feature caused by erosion?
Terminal moraines are not formed due to erosion but rather deposition. They are ridges of glacial till that mark the farthest advance of a glacier and are deposited as the glacier retreats. Erosion by the glacier does contribute to the material found in terminal moraines, but the feature itself is primarily a result of deposition.
How can terminal and lateral moraines form glacial lakes?
A lateral moraine is formed at the side of a glacier. Falling ice can melt and form a lake. Similarly, a terminal moraine marks the farthest advance of a glacier where all the ice typically melts.
Under what circumstances will the front of a glacier advance?
A glacier is always moving forward (downhill). In the winter, the glacier usually isn't melting and its front edge (or "toe") will advance downhill. In the summer, the toe of the glacier usually melts faster than the glacier is moving forward, causing the front edge of the glacier to recede. If the recession in the summer is greater than the advance in the winter, then the glacier as a whole is receding and will eventually disappear. That is what is currently happening to most of the glaciers in North America and many other places around the world.

What is the moraine called that marks the farthest advance of a glacier?
The moraine that marks the farthest advance of a glacier is called a terminal or end moraine. It forms from the accumulation of debris and sediment that the glacier pushes forward as it advances. Once the glacier retreats, this moraine remains as a distinct ridge or hill, indicating the maximum extent of the glacier's reach.
The farthest advance of a glacier is marked by terminal?
The farthest advance of a glacier is marked by a terminal moraine, which is a ridge of debris deposited at the glacier's leading edge as it moves and melts. This accumulation of rocks, soil, and sediment provides a clear indicator of the glacier's maximum extent. Terminal moraines can vary in size and shape, depending on the glacier's characteristics and the environment in which it exists. They are significant features in glacial landscapes and can help scientists understand past glacial activity.

What is the difference between terminal moraine and lateral moraine?
Terminal moraine is a ridge of till that forms at the farthest advance of a glacier, marking its maximum extent. Lateral moraine, on the other hand, is a ridge of till that forms along the sides of a glacier as it flows and carries debris from the valley walls.
What type of moraine form Materials bulldozed at the front of the glacier?
The type of moraine formed by materials bulldozed at the front of a glacier is called a terminal moraine. This accumulation of debris marks the furthest advance of the glacier and typically consists of a mix of soil, rocks, and other sediments that have been pushed forward as the glacier moves. Terminal moraines often create a distinct ridge or hill-like formation at the glacier's edge.
What is a terminal moraine and how is it formed?
A terminal moraine is a ridge of glacial debris, such as rocks and soil, that marks the furthest advance of a glacier. It is formed as the glacier pushes and deposits a mixture of rocky material at its leading edge, creating a distinct landform that can stretch across a valley floor.
What relationship between accumulation and ablation is necessary for the ice front of a glacier to advance?
The accumulation or snowfall rate needs to exceed the ablation which is the snow or ice melting rate in order for a glacier to advance or move forward. ~hope I'm right!
What was the farthest German advance east during WW2?
The Ukraine was the farthest they got. See map on link below.
