Dose a valley glacier or a contenental glacier or both cover entire land areas?

Valley glaciers are formed in high altitudes (e.g. mountains) and continental glaciers are formed in high latitudes (e.g. Greenland). Therefore, they both cover land areas but continental glaciers generally cover more area.

What two types of glaciers are giant sheets of ice that cover large areas of land?
Continental glaciers form in large flat areas. They spread across entire continents and make flattened landscapes. :)
What is continental glacier?
A continental glacier is a glacier that spreads out from a central mass of ice.Hope this helps.Answer 2:A continental glacier is a an ice sheet covering much of a continent
Why are there no Piedmont glaciers to be fond in Anchorage Alaska?
The geography of the Anchroage area won't support a Piedmont glacier. This glacier (the Piedmont glacier) is characterized by large stagnant ice sheets where a glacier or glaciers "doesn't/don't have anywhere to go" for lack of an outlet. All the areas around Anchroage, Alaska slope down to the sea. There is no place for the ice of a Piedmont glacier to "build up" for lack of a way to "break out" or to "get stopped" to form this glacier.
What are glacial moraines?
A moraine is any glacially formed accumulation of unconsolidated glacial debris (soil and rock) which can occur in currently glaciated and formerly glaciated regions, such as those areas acted upon by a past ice age. This debris may have been plucked off the valley floor as a glacier advanced or it may have fallen off the valley walls as a result of frost wedging or landslide. Moraines may be composed of debris ranging in size from silt-sized glacial flour to large boulders. The debris is typically sub-angular to rounded in shape. Moraines may be on the glacier's surface or deposited as piles or sheets of debris where the glacier has melted. Moraines may also occur when glacier- or iceberg-transported rocks fall into the sea as the ice melts.
How does a glacier expand and contracts or recedes over time?
During cold climatic periods the glaciers stop melting and new snow at the top of mountainous areas builds up over a number of years to add to the upper parts of the glaciers. The ice in the glaciers moves downhill, (because of gravity), and it expands down the valley. When the climate becomes warmer the ice and snow melts during successive summers so the glacier is deprived of new snow and retreats.

What are glaciers and how are they formed?
Glaciers are large blocks of ice found in areas of high latitude or high altitude. They erode in two ways: abrasion and plucking. Abrasion can only occur when the glacier is moving. Subglacial debris embedded in the base and sides of the glacier scrapes the valley base and walls as it moves through the valley. Plucking involves the glacier moving over a resistant outcrop of rock where pressure-melting creates meltwater. The meltwater then flows to an area of low pressure where is subsequently refreezes attaching itself to both the surrounding rock and the glacier itself. The glacier then advanced physically ripping the rock out of the valley.
How do valley glacier modify the mountainous areas where it forms?
a. deepens itb. straightens itc. all of thesed. only deepens it and widens itC.) all of these

Nile Valley, Tigris and Euphrates Valleys, Indus Valley, Yangtse Valley.
What areas in antipolo with fault line?
valley golf subdivision
How do glaciers retreat?
Glaciers retreat when the glacier melts more ice than is in input by snow.They cannot be anywhere near or in hot areas or they will melt.
What is a definitionn of a glacier?
A glacier is a large mass of ice that forms over time from compacted snow in areas where snow persists year-round. Glaciers slowly flow downhill under the influence of gravity, shaping the landscape through processes such as erosion and deposition.
What is a hollow glacier called?
When a glaciers hollows out areas that become lakes its called calving!!
