The process in which rock fragments freeze to the bottom of a glacier and are then carried away when the glacier moves is called plucking. After the last ice age, stranded ice blocks left behind by the continental glacier melted and formed kettles.

Plucking is another process where moving glaciers pick up debris by freezing onto rocks, plucking them off, and carrying them along as the glacier moves. This process helps transport rock fragments and sediment to new locations, contributing to the shaping of the landscape.
A glacier transports a variety of materials, including rock debris, sediment, and ice. As glaciers move, they erode the landscape, picking up and carrying fragments of rock and soil along with them. This process can lead to the deposition of these materials in new locations when the glacier melts or retreats. The movement of glaciers plays a significant role in shaping landforms and influencing geological processes.
The two processes are abrasion and plucking.What processes lead to glacial erosion? Describe them.The two main processes that lead to glacial erosion are plucking and abrasion. Plucking is the process by which a glacier picks off rocks as it blocks over the land. The rock fragments freeze to the bottom of the glacier, gouging and scratching the bedrock as the glacier advances in the process of abrasion.
They break them up into smaller pieces of rock (eventually all the way down to sand or other fine pieces of earth) and/or smooth their rough edges in a process called weathering.They move them down-flow in the process known as erosion.The rock particles which are carried by the rivers and glaciers will ultimately be deposited when the water or ice can no longer transport them. After deposition, they may eventually become sedimentary rock, through the processes of lithification (compaction and cementation).

Glaciers can carry sediments through a process called erosion, where they pick up rock fragments and soil as they move. When glaciers deposit these sediments in new locations, it is considered a deposition process, contributing to landform formation.

Glaciers pick up rocks through a process known as glacial erosion. As glaciers move, they scrape against the land beneath them, incorporating rocks and debris into the ice. This occurs through two main mechanisms: abrasion, where the glacier grinds the rocks beneath it, and plucking, where the ice freezes around rocks and pulls them away as it moves. The collected rocks and sediments are carried along with the glacier until they are eventually deposited when the glacier melts.
Glacial polish results from the grinding action of glaciers as they move and slide over bedrock, smoothing and polishing the surface of rocks. This process is primarily caused by the abrasion of rock particles and debris carried by the glacier against the bedrock.
The glacier that has frozen to the bedrock is called a "frozen glacier." When a glacier becomes warm enough to melt at its base, the meltwater effectively 'glues' the glacier to the underlying bedrock. This process allows the glacier to adhere strongly to the bedrock and can help stabilize it.
This process is known as abrasion, where the rocks carried by a glacier scrape and wear down the surface of the landscape as the glacier moves. They act like a giant sandpaper, smoothing and sculpting the underlying rock. Over time, this abrasive action helps to shape the landforms carved by glaciers.
Glaciers contribute to physical weathering through a process called abrasion, where the movement of ice and rock fragments scours and erodes the underlying bedrock. As glaciers move, they pick up and carry large boulders and rocks that act as tools to grind and shape the landscape beneath them. Over time, this process can create valleys, fjords, and other glacier-carved landforms.
Glaciers erode by abrasion when they drag rocks and sediments along their base and sides, creating a sandpaper effect. This process occurs as the glacier moves, grinding, scratching, and smoothing the underlying bedrock and carving out deep valleys. The debris carried by the glacier further enhances the abrasion process as it scrapes against the surface.
