Glaciers move (very slowly) therefore functioning as a source of erosion.
They are also a source of weathering "in situ" due to their freeze/thaw cycles causing expansion/contraction of adjacent stone, causing physical deformation.

Glaciers contribute to weathering by freezing and thawing, causing rocks to crack and break apart through a process called frost wedging. Additionally, glaciers erode the landscape by plucking and abrasion, picking up and carrying away rocks and sediment as they flow over the land.
Acid rain can contribute to both weathering and erosion. Weathering refers to the breakdown of rock materials due to chemical or physical processes, which can be enhanced by acid rain. Erosion, on the other hand, involves the removal and transport of weathered materials by agents like water or wind, which can also be influenced by acid rain.
Both water and glacier erosion involve the movement and transportation of sediment and rocks. They both contribute to shaping the landscape by wearing down surfaces over time. Additionally, both processes can create valleys, canyons, and other geological features through their erosive actions.
The twelve apostles, a collection of limestone stacks off the coast of Australia, have been affected by both weathering and erosion. Weathering breaks down the limestone into smaller pieces, while erosion by wind and water shapes the stacks into their distinct formations.

Erosion and weathering are interrelated processes that work together to break down and transport rock material. While erosion physically removes the material from its original location, weathering breaks it down chemically or physically. The combined effects of both erosion and weathering can cause significant changes to the Earth's landscape over time.
