This is likely referring to till, which is a mixture of unsorted materials (rock, sand, and silt) left behind by a retreating glacier. Till layers can vary in thickness and composition, and they are often seen in areas where glaciers have once existed.
A glacier is a 'river' of ice. In cold places where precipitation falls as snow rather than rain, the snow thickness builds up and up and forms a field of ice as its compacts. Masses of ice are not solid but flow very slowly down hill under the force of gravity. This ice flow is called a glacier. Glaciers flow down hill and as they do so it gets warmer and the ice at the tip of the glacier melts (they turn into rivers of water). If the climate is cold then this melting happens less fast than the snow is supplying new ice at the top and the bottom of the glacier will advance (the glacier gets longer). If the climate is warming then the melting happens faster than the snow is supplying new ice and the bottom of the glacier will retreat back up towards the snow/ice field (the glacier gets shorter) All of earths glaciers are currently getting shorter - the Glaciers are in retreat. This is because earths climate is getting slightly warmer.
A tarn is a small, steep-banked mountain lake, formed when a glacier advancing down a slope scoops material out of the ground in a "cirque" at the base of the slope. (Essentially, it continues downward into the ground before moving horizontally again.) When the glacier melts, the depression can fill with water, and is refilled by melting snow unless it becomes filled by silt.
The Tasman Glacier is a valley glacier. It is located in the Southern Alps of New Zealand and flows down the Tasman Valley. Valley glaciers form in mountainous regions and flow along valleys carved by rivers.
A tidewater glacier is a glacier that flows down into the ocean or a body of water. These glaciers calve, or release icebergs, into the water, causing a dynamic interaction between the glacier and the ocean.
This is likely referring to till, which is a mixture of unsorted materials (rock, sand, and silt) left behind by a retreating glacier. Till layers can vary in thickness and composition, and they are often seen in areas where glaciers have once existed.
The glacier is melting faster than it is sliding down the valley.
Basal slip occurs when the glacier rests on a slope. Pressure causes a small amount of ice at the bottom of the glacier to melt, creating a thin layer of water. This reduces friction enough that the glacier can slide down the slope. Loose soil underneath a glacier can also cause basal slip.
it melts
Any glacier moves down a mountain or other slope because of the influence of gravity overcoming the influence of friction.

Yes by retreating and when Harald followed them the Normans cut them down
The ozone layer slows down meteorites. This is a layer of atmosphere.
Yes it is. It is the name of one specific glacier.
