When and how do glaciers advance?
Glaciers advance when the weight of the new snow that piles on top of the glacier gets heavy enough to push it downhill.
If you saw long scratch marks on a flat rock surface you would suspect what?
The geologist would suspect that these were striae, which are marks made by a glacier dragging rocks over the bedrock.
What is a ridge at the farthest point reached by a glacier?
This is known as a Lateral moraine. Please see the related link for more information.
Under what circumstances will the front of the glacier advance Retreat Remain history?
Glacial advance and retreat is determined by the balance between the accumulation of snow and the removal of ice by sublimation, melting, and calving (ablation). When the rate of ablation below the snowline equal
What is a glacier snout?
a glacier snout is the front of the glacier :)
What is the maraine called that marks the farthest advance of a glacier?
A terminal moraine marks the farthest advance of a glacier.Locally, we have some terminal moraines of hundreds of thousands of years old, and ranging down to about 18 000 years.
What marks the farthest advance of a glacier?
An extensive pile of till (loose debris & rocks) called an end moraine can build up at the front of the glacier and is typically crescent shaped. Two kinds of end moraines are recognized: terminal and recessional moraines. A terminal moraine is the ridge of till that marks the farthest advance of the glacier before it started to recede. A recessional moraine is one that develops at the front of the receding glacier; a series of recessional moraines mark the path of a retreating glacier.
How can terminal and lateral moraines form glacial lakes?
A lateral moraine is formed at the side of a glacier. Falling ice can melt and form a lake. Similarly, a terminal moraine marks the farthest advance of a glacier where all the ice typically melts.
Under what circumstances will the front of a glacier advance?
A glacier is always moving forward (downhill). In the winter, the glacier usually isn't melting and its front edge (or "toe") will advance downhill. In the summer, the toe of the glacier usually melts faster than the glacier is moving forward, causing the front edge of the glacier to recede. If the recession in the summer is greater than the advance in the winter, then the glacier as a whole is receding and will eventually disappear. That is what is currently happening to most of the glaciers in North America and many other places around the world.
What was the farthest German advance east during WW2?
The Ukraine was the farthest they got. See map on link below.
When and how do glaciers advance?
Glaciers advance when the weight of the new snow that piles on top of the glacier gets heavy enough to push it downhill.
What relationship between accumulation and ablation is necessary for the ice front of a glacier to advance?
The accumulation or snowfall rate needs to exceed the ablation which is the snow or ice melting rate in order for a glacier to advance or move forward. ~hope I'm right!
How does a glacier advance?
Gravity pulls it twords the earth, and it melting may have something to do with it. God luck out there. ;)
What are glacier scratches?
These marks are called striae and are the parallel marks left on the bedrock when rocks entrained in the glacier scrape along the glacier's base..These are part of the origin of the features called moutonne roches = rock sheep. Which were NOT your usual merino, but were the nick name given to judges wigs, which, when lying on the bench, had similarities with the geological features; the shape being similar, and the striae resembling the marks left on the rock. At least according to some authorities such as Holmes.
What is advancing glacier?
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.
What marks the place farthest south that the sun ever shines directly overhead?
tropic of Capricorn
What is the farthest in advance credit card expiration date?
10 years is a safe assumption from my research.
