How did Lambert glacier get its name?
The Lambert Glacier is a Valley Glacier. It is also an Ice Stream.
What example of water transferring from the atmosphere to the cryosphere?
In New Zealand there are Franz Josef glacier and Fox glacier In the French Alps there is the Mer de Glace The largest glaciers in the world are the ice sheets on Greenland, the second largest glacier in the world, and the ice sheet on Antarctica is the largest in the world. glaciers are riveres of ice that moves very slowly.
What is the largest glacier in Alaska?
Malaspina Glacier is the largest glacier in the state of Alaska, with an area of 1,500 square miles ChaCha!
What is the role of research in advancing knowledge?
Research is precisely for advancing knowledge of a process or theory
The mixture of sediments deposited directly by a glacier is called?
Sediments directly deposited by the glacier are called till.
Will plucking occur if a glacier is NOT advancing?
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.
How do you tell if a valley glacier is advancing or retreating?
Valley glaciers are typically advancing when their terminus is pushing forward, causing the glacier to grow in size. Conversely, they are retreating if the terminus is melting or receding, leading to a decrease in glacier size. Monitoring changes in the glacier front position over time can help determine if it is advancing or retreating.
Removal of rock by an advancing glacier?
Actually, when first advancing, a glacier will just over ride obstacles in front of it. It will NOT bulldoze them. There are lots of good photos of this. Ask your tame glaciologist. Eventually, when the glacier fully covers an obstacle, the rocks embedded in the glacier and those at the base, will grind away at the obstacle.
What is streams formed by melting ice when a valley glacier stops advancing called?
Meltwater streams formed by melting ice when a valley glacier stops advancing are called proglacial streams. These streams are commonly found at the terminus of a glacier where melting ice produces large volumes of water that flow down the valley.
When a glacier is growing you say it is?
When a glacier is growing, it is experiencing positive mass balance, meaning that it is accumulating more snow and ice than it is losing through melting or iceberg calving. This process leads to the glacier advancing in size and sometimes even causing the glacier's terminus to extend further down its valley.
What does the location of a terminal moraine tell you about the glacier?
The location of a terminal moraine indicates the furthest advance of a glacier, marking the point where it deposited debris as it melted. If the moraine is located further from the glacier's current position, it suggests the glacier has retreated significantly over time. Conversely, a terminal moraine close to the glacier's edge may indicate that the glacier is still actively advancing or has recently stabilized. Overall, the moraine provides insights into the glacier's movement and historical dynamics.
What has been the movements of the Fox Glacier over the last 100 years?
The fox glacier has been retreating for most of the last 100 years but started advancing in 1985. In 2006 the advance rate was 1 metre a week.
Which is faster the advance or the retreat of an ice sheet?
Glaciers are advancing and retreating all the time. During the summer most will be retreating, during the winter most will be advancing. Therefore the world is not in a 'glacial advance or retreat' because each glacier is independent.
Which moraines is not a characteristic of continental glaciation?
Terminal moraine is not a characteristic of continental glaciation. Terminal moraines are formed at the furthest extent of a glacier, marking the point where it stopped advancing.
Does a glacier have mass movement?
Yes, a glacier exhibits mass movement as it flows under the influence of gravity. This movement occurs as the ice deforms internally and slides over the underlying bedrock or sediment. The process can result in the glacier advancing, retreating, or deforming, contributing to the landscape through erosion and deposition. Thus, glaciers are dynamic systems that continuously reshape their environment.
What happens if the glacier stops for a while then retreats?
If a glacier stops advancing for a while, it may indicate a temporary balance between accumulation and melting. During this pause, processes like melting, sublimation, and calving can result in the loss of mass. When the glacier eventually retreats, it typically exposes the underlying landscape, potentially leading to changes in local ecosystems and hydrology. Additionally, the retreat can contribute to rising sea levels if the glacier is part of a larger ice sheet.
The downstream end or snout of a glacier advances over periods of time during which ablation exceeds accumulation?
The glacier snout advances over time when more ice is added through accumulation than lost through ablation. When ablation exceeds accumulation, the snout retreats instead of advancing. This balance between accumulation and ablation determines the overall size and position of a glacier.
