Where can one find a glacier equilibrium line?
A glacier equilibrium line, also known as the equilibrium line altitude (ELA), can be found at the point on a glacier where the amount of snow accumulation equals the amount of ice ablation (melting and sublimation) over a year. This line typically varies with altitude, latitude, and local climate conditions and is often located at higher elevations in warmer climates and lower elevations in colder regions. It can be observed on glacier surfaces during the melting season when the seasonal snow cover recedes.
Which parts of glaciers and its triburitaries moves most quickly?
Glacier speed is not constant across the glacier. The top half of the glacier moves faster than the bottom, presumably because of friction. The sides also flow slower than the middle, also because of friction. The middle of the glacier at the equilibrium line flows fastest, the head and terminus flow slower. Above the equilibrium line the glacier grows faster than it melts; this is called the accumulation zone. Below the equilibrium line, the glacier melts faster than it grows; this is called the ablation zone.
What is The line dividing the zone of accumulation from the zone of ablation on a valley glaciers is called?
The line dividing the zone of accumulation from the zone of ablation on a valley glacier is called the equilibrium line. This line marks the point where accumulation (snowfall) equals ablation (melting and sublimation), influencing the glacier's overall mass balance and movement.
What situation allows a glaciers size to be maintained?
a glacier has a snowline at the same height as the wastage line.
An ice front is likely to be stationary when the glacier does what?
An ice front is likely to be stationary when the rate of ice accumulation in the glacier matches the rate of ice loss due to melting or calving at the front. This equilibrium state is known as a stable glacier front, where there is no net advance or retreat of the ice front.
How does the glacial budget control the migration of the equilibrium line?
The glacial budget, which consists of accumulation and ablation of ice mass, directly influences the position of the equilibrium line on a glacier. If accumulation exceeds ablation, the equilibrium line moves towards the glacier's top, leading to glacier advance. Conversely, if ablation exceeds accumulation, the equilibrium line shifts downslope, causing glacier retreat.

What is a line of low hills formed by rock pushed at the front of a glacier?
A moraine is a line of low hills formed by rock and debris pushed to the front of a glacier as it advances. This material is deposited as the glacier melts, creating distinctive landforms in its path.
How are conditions of pressure and temperature at which two phases coexist in equilibrium shown on a phase diagram?
On a phase diagram, the conditions of pressure and temperature at which two phases coexist in equilibrium are represented by a line. This line is called the phase boundary or phase equilibrium line. It separates the regions where the two phases exist in equilibrium from the region where only one phase is present.

An ice front is likely to be stationary when the rate of ice accumulation in the glacier matches the rate of ice loss due to melting or calving at the front. This equilibrium state is known as a stable glacier front, where there is no net advance or retreat of the ice front.
What is the name of a curved line on a graph?
price or equilibrium A curve
What are terminal moraine?
Terminal moraines are ridges of glacial debris deposited at the furthest point reached by a glacier. They mark the end of a glacier's advance and can be seen as a line of debris and rocks left behind as the glacier melts and retreats. These moraines are called "terminal" because they are found at the glacier’s terminus.
Where the Siachen glacier is located in Pakistan?
The Siachen Glacier is located in the eastern Karakoram range in the Himalaya Mountains, just east of the Line of Control between India-Pakistan.
How many road miles between SC and Glacier National Park?
The driving distance from the South Carolina state line to Glacier National Park is about 2,254 road miles.
