What is a glacier snout?
A glacier snout is the terminus or end point of a glacier where ice and meltwater are released. It is where the glacier meets lower elevations and warmer temperatures, causing melting and ice loss. The snout can vary in shape and size depending on the glacier's dynamics.
The lower portion of a glacier where there is an annual loss of ice due to melting?
That area is known as the ablation zone, where the rate of melting exceeds the rate of snow accumulation. It is located at the lower end of the glacier and is crucial in determining the overall health and size of the glacier.
The end or outer margin of a glacier?
The end or outer margin of a glacier is called the glacier terminus. This is where the glacier ends and begins to melt or calve into the surrounding environment, such as a body of water or land. Changes in the glacier terminus are closely monitored by scientists to understand the health and movement of the glacier.
What is crevasse slip?
A crevasse slip is a type of glacier movement where the upper portion of the glacier slides down relative to the lower portion, causing the opening of crevasses or cracks on the surface. This movement can be triggered by internal glacier stress, changes in temperature, or the presence of water at the base of the glacier. Crevasse slips can pose risks to glacier travelers and mountaineers.
When does a glacier deposit its load?
A glacier deposits its load when the ice melts, releasing the sediments and rocks it carried. This can happen when the glacier reaches lower elevations or warmer temperatures, causing the ice to melt and the sediments to be left behind.
Hanging valley and a glacial trough?
Glacial Trough (U-shaped valleys) - Flat-bottomed valley with steep sides produced by the erosion of the floor and sides of the valley by an alpine glacier as its sediment abrades while the glacier flows downhill. On the topographic maps they are recognized by closely spaced contours along the valley sides and widely spaced contours on the valley floor.Hanging Glacial Troughs - Formed when the down-cutting erosion of the main valley glacier exceeds that by the tributary glacier. The tributary glacier flows onto the main glacier and thus has an erosional base level of the elevation of the main valley glacier. After melting, the lower portion of the tributary glacial trough is then left hanging above the main floor of the glaciated valley. On maps they are recognized by more widely spaced contours across a stream in the upper portion than in the lower portion (where the modern stream cascades into the main valley below).
Is a fiord a period of the Ice age?
A fiord is a drowned, steep-sided valley previously cut by a glacier when sea level was lower.
What is the location of the onyx river in antarctica?
The Onyx River is the longest river in Antarctica. It is comprised mostly of melt water and flows through Wright Valley from Wright Lower Glacier and Lake Brownworth at the bottom of the glacier to Lake Vanda. It is only 20 mile long.
What is the lower end of a glacier called?
The area that is melting faster than it is accumulating is the "Zone of Ablation." The very bottom end of a glacier is typically called its "foot."
What is a glacier snout?
A glacier snout is the terminus or end point of a glacier where ice and meltwater are released. It is where the glacier meets lower elevations and warmer temperatures, causing melting and ice loss. The snout can vary in shape and size depending on the glacier's dynamics.
What is the longest river in Antartica?
The Onyx River is an Antarctic meltwater stream which flows westward through the Wright Valley from Wright Lower Glacier and Lake Brownworth at the foot of the glacier to Lake Vanda, during the few months of the Antarctic summer. At 32 kilometres (20 mi) in length, it is the longest river in Antarctica.
What are the tributaries of the River Onyx?
Wright Lower Glacier and Lake Brownworth at the foot of the glacier -

When was Lower Inn Valley Railway created?
Lower Inn Valley Railway was created in 1858.

What the 2 most common kinds of glaciers?
There are 2 main types of glaciers, Continental is one, they float away from central regions. The second is alpine or valley which are the glaciers that flow down the valley from the mountain.
