Glacial drift.
Glacial drift.
When a glacier melts it deposits the sediment it eroded from the land, creating various landforms.
Moraines are formed by the deposition of glacial debris as a glacier moves and erodes the land. As the glacier melts, it leaves behind ridges and mounds of unsorted sediment. The size and shape of a moraine can vary depending on the glacier's movement and the type of sediment deposited.
Cirque erosion results in the formation of bowl-shaped depressions at the head of a valley glacier. Deposition can occur when the glacier melts, depositing sediment and creating a small lake called a tarn in the cirque basin.
A small hill-like mound formed from the deposits as a glacier recedes is called a moraine. Moraines are composed of till, which is a mix of rock, sediment, and debris that the glacier carries and deposits as it moves and melts.
The dropping of sediment from wind or water that slows down is called sediment deposition. When ice melts and releases sediment it carries, it is known as glacial meltwater sedimentation.

These ridges are called lateral moraines. They are formed by the debris and sediment that accumulates along the edges of the glacier as it moves downhill. When the glacier melts, it deposits this material, creating distinct ridges along the sides of the valley.
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.
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.
