Glacier formation itself doesn't directly cause another form of erosion and sedimentation. However, glaciers are powerful agents of both erosion and sedimentation, and their processes are closely linked to other geological processes that can lead to different forms of erosion and sedimentation.

Here are a few examples:

* Plucking and Abrasion: Glaciers erode the land through plucking (picking up rocks and sediment) and abrasion (grinding and scraping the surface with embedded rocks). This can lead to glacial flour, a fine sediment that can be carried by rivers and deposited as loess.

* Ice Age Meltwater: As glaciers melt, they release large amounts of meltwater, which can carve out valleys and transport sediment. This can lead to glacial outwash plains, areas of deposition where meltwater rivers deposit sediment.

* Isostatic Rebound: As glaciers melt, the land beneath them begins to rise, a process called isostatic rebound. This uplift can create new landforms and expose bedrock that can be eroded by other processes, such as weathering.

* Glacial Lake Formation: Glaciers can create lakes by eroding depressions in the landscape. These lakes can then become sources of sediment, leading to lacustrine sedimentation.

Therefore, while glacier formation itself is not a separate form of erosion and sedimentation, it is a primary driver of these processes and leads to various other geological phenomena that contribute to them.
