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.

When glaciers move, they pick up rocks of various sizes. These rocks are then dragged along the bedrock beneath the glacier, causing abrasion. The rocks act like sandpaper, scraping and carving grooves and scratches into the bedrock as the glacier advances.
The process by which glaciers pick up rocks is called "glacial plucking." As glaciers move, they exert pressure on the underlying bedrock, causing fractures that allow them to pull away pieces of rock. This process contributes to the erosion and shaping of the landscape as the glacier transports the debris.
It is proven that this is called glacier plucking or just plucking.
The picking up and movement of earth beneath a glacier is referred to as glacial erosion. This process involves the glacier scraping and plucking rocks and sediment from the ground as it flows, and can result in the formation of landforms such as valleys, cirques, and moraines.
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.

Glaciers pick up rocks through a process called glacial abrasion and plucking. As glaciers move, they exert pressure on the underlying rock, causing fractures and loosening debris, which is then incorporated into the ice. The movement of the glacier grinds down these rocks, creating a characteristic striated surface beneath. Additionally, meltwater can seep into cracks in the bedrock, freezing and expanding to help lift larger rocks and boulders into the glacier.
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.
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.
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.
The process by which a glacier loosens and moves rock is called glacial erosion. It occurs when the glacier's immense weight and movement cause it to pick up and carry rock fragments. As the glacier moves, these rocks scrape and grind against the underlying surface, gradually wearing it down and forming characteristic features like U-shaped valleys and striations on bedrock.
