The type of succession that occurs when a glacier melts, exposing bare rock, is called primary succession. This process begins with the colonization of pioneer species, such as lichens and mosses, that can thrive in harsh conditions. Over time, these organisms help to create soil, allowing more complex plant species to establish, leading to increased biodiversity and ecosystem development.
Primary Succession
Water
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.
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.

What can happen when the glacier melts in a cirque
When a glacier melts it deposits the sediment it eroded from the land, creating various landforms.

Moraines are not caused by erosion, but rather by the deposition of sediment and rocks carried and deposited by a glacier as it moves and melts. Erosion occurs as the glacier carries material away from its original location.

An example of a glacier moving a boulder would be when a large rock is picked up by a glacier as it flows downhill, and is transported along with the ice to a new location. This process, known as glacial plucking, occurs when the ice melts and the boulder is deposited on the ground.
the glacier dropped small rocks as it melted. An erratic is a large boulder left behind after a glacier has melted
