When a glacier scrapes along the ground, it plucks rocks out of the ground underneath them, then carries on advancing until it melts and then deposits those rocks even thousands of km from where they were picked up, giving rise to the term alien/erratic rocks (a rock which has been moved from its origin by natural processes and deposited in an area which it doesn't 'belong' geologically).
Picking
words that describe glacier
Yes, glacier is a noun. "Glacial" is the adjective form.
Yes it is. It is the name of one specific glacier.
There are three nouns. They are pressure, weight, and glacier.
It is proven that this is called glacier plucking or just plucking.
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.
The base of the glacier, where it is in contact with the rocks beneath it.
Plucking
Valleyglaciers:)
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.
Plucking and Abrasion.
Plucking erosion is a glacial process where meltwater penetrates cracks in a glacier and freezes, causing the ice to expand and pull rock fragments from the bedrock beneath the glacier. This plucking action allows the glacier to transport the rock debris as it flows, contributing to the erosion and shaping of the landscape.
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 a form of glacial erosion where a glacier will pick up and carry pieces of bedrock as it moves. This process occurs when meltwater at the base of the glacier freezes onto the rock, and as the glacier moves, it pulls these frozen rock pieces along, causing erosion. Plucking can result in the removal and transportation of large rock fragments by glaciers.
The basal sliding zone
i guess it makes the glacier bigger because it's picking up surface materials?
