The end or outer margin of a glacier?
There are so many variations of glacier types. If the head of the glacier is high in the mountains, then the lower end could possibly be called the mouth of the glacier?
The lower portion of a glacier where there is an annual loss of ice due to melting?
Ablation Zone
What change would occur in a glacier if average annual temperature rose and the precipitation decreased?
The glacier would retreat. The rise in temperature would cause the glacier itself to start melting, and in addition, would lower the amount of precipitation in the form of snow at the top of the glacier. It would be rain instead. Lowering the precipitation would cause less ice formation as well and would also contribute to the glacier retreating.
How was Arizona's basin and range formed?
by normal fault uplifting the mountains, and creating a lower level valley because the valley would be along the lower level hanging wall.
What happens to a glacier when they get very heavy?
The density of ice at 0°C is 0.9167 g/cm³. The density increases slightly at lower temperatures. Therefore, the volume and temperature of the glacier is needed in order to calculate the exact weight.
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 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.
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 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 -

Is the valley of kings in upper or lower Egypt?
the valley of the kings is located in lower Egypt
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."
