A Glacier will advance when the snow deposited in the collection zone exceeds the rate of melting at the terminus. There will be some time delay between these events, even a steep glacier will take a few years between the events.
A glacial advance occurs when the snout advances faster than it can melt.
In most glaciers this reflects a heavier than usual snowfall in the headwater catchment area some time before - perhaps years.
For a very steep falling glacier, this excess precipitation may have only occurred within the last year or so.
Glacial advance occurs when the leading edge of a glacier is able to move ahead faster than it can melt.
A glacier that is still growing, as shown by its snout advancing is such.
GRAMMAR CORRECTION: What is AN advancing glacier!
When the rate of advancement is higher than the rate of melt. So, the glacier is growing.
The Lambert Glacier is a Valley Glacier. It is also an Ice Stream.
Research is precisely for advancing knowledge of a process or theory
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.
Malaspina Glacier is the largest glacier in the state of Alaska, with an area of 1,500 square miles ChaCha!
Sediments directly deposited by the glacier are called till.
Yes, because glacial ice is still moving inside the glacier even if the glacier's front is not advancing.
You can tell if it's retreating if it slows it's speed in the glacier. You can tell if it's advancing if it increases in speed.
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.

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.
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.
No, Weird huh? When you get that much ice in one place the weight and pressure make it move like a plastic and "Flow" almost like water or Lava. The glacier flows down the valley advancing as it melts.
The embedded rocks grind away the bedrock beneath the glacier, leaving scratches, striae, on the rock. In doing this, they tend to round off the corners of all but the largest boulders, and produce huge quantities rock flour. The smaller rocks tend to polish the basement. If upstream there is a harder rock, such as volcanic or granite, then the bed will be more deeply excavated than if all the grind stones are homogeneous. The rocks enter deeply into the glacier at bergschrunds (crevasses at glacier edge), or through ordinary crevasses where the glacier goes over a step in its bed.

A long smooth,canoe-shaped hill that is usually found in groups,shaped by an advancing glacier .
It is a valley glacier
yes glacier canyon is a real glacier
