lateral moraine
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.
Glacial deposits, often referred to as glacial drift, are the general term for all sediments deposited by a glacier. This can include material like till, moraine, and glacial erratics left behind as the glacier moves and melts.
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.
The term for all sediments of glacier origin is "glacial till." It consists of a mixture of rock fragments of various sizes that are deposited directly by the ice as it moves and melts.
Eskers are winding ridges of sediment deposited by meltwater streams flowing under glaciers. Kettle lakes are formed when a block of ice from a retreating glacier gets buried in sediment and then melts. Both eskers and kettle lakes are common features of glacial landscapes.
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.
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.

An esker is a glacial landform that is created by deposition. Eskers are long, winding ridges of sand and gravel left behind by streams within or under glaciers. They form as the glacier melts and recedes, leaving behind sediment deposited by the flowing water.
The process of a glacier picking up rocks and transporting them is called "glacial entrainment" or "glacial plucking." When a glacier moves over bedrock, it can freeze onto and pluck rocks from the surface, incorporating them into the ice. These rocks can then be transported and eventually deposited as the glacier flows and melts.
Glaciers cause erosion by plucking and abrasion as they move, picking up rocks and debris and grinding them against the landscape. This eroded material is then transported and deposited as the glacier melts, forming moraines, till, and other glacial landforms. Erosion and deposition by glaciers can reshape the landscape over time, creating valleys, fjords, and glacial lakes.

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.

The unsorted rock material deposited by ice when it melts is called glacial till. Glacial till can vary in size from clay to boulders and is typically a mixture of rock types that were picked up and carried by the moving glacier.
