A glacier will pick up rocks as it moves downhill. It is these rocks that gouge out the underlying ground and will eventually form a 'U' shaped valley. As the rocks are also ground down into a paste, the bed rock layers the glacier moves over can become quite polished.
It is proven that this is called glacier plucking or just plucking.
The base of the glacier, where it is in contact with the rocks beneath it.
Plucking can still occur even if a glacier is not advancing. Plucking is more influenced by the presence of meltwater and the freezing and thawing of water in crevasses than the overall advance or retreat of the glacier.
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.
The process when a glacier loosens and moves rocks is called glacial erosion. As glaciers advance, they pick up and transport debris through a combination of plucking and abrasion. Plucking occurs when ice freezes around rocks and pulls them away as the glacier moves, while abrasion involves the grinding of rock surfaces as the glacier slides over them, effectively wearing them down. This process shapes the landscape and contributes to the formation of various geological features.

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.
The three main types of glacial erosion are plucking, abrasion, and quarrying. Plucking occurs when rocks are lifted and carried away by the moving glacier. Abrasion happens when rocks and sediment carried by the glacier scrape against the bedrock, wearing it down. Quarrying involves the glacier breaking off and carrying away large chunks of bedrock.
Two types of glacial erosion are plucking, where rocks and sediments are plucked from the bedrock by the moving glacier, and abrasion, where the glacier's movement causes it to scrape and polish the underlying bedrock.

Plucking occurs when glaciers freeze onto rocks and then pull them out as they move, creating jagged features. Abrasion happens when rocks and sediments in the glacier's base scrape and wear away the underlying rock as the glacier flows, smoothing and polishing the surface. Together, plucking and abrasion are key processes in shaping the landscape through glacial erosion.
Plucking
The glacier is melting on the mountain and underneath it is like a river which eroding a side of the mountain when the glacier melts enough, it will slide down the mountain and into the lake that the river underneath the glacier had created. Hope this helps :)
Plucking is the process in which a glacier freezes around cracked and broken rock and when it moves downhill, the rock is plucked from the back wall of the glacier.
