Are there glaciers in the desert?
THE Himalayan desert of Ladakh is home to this majestic tower of ice, known as an ice stupa, after the domed Buddhist buildings.
What is the difference between glacier and ice?
Unlike ice shelves, glaciers are land-based. While glaciers are defined as large sheets of ice and snow on land, ice shelves are technically part of the ocean.
What is the main difference between ice sheets and glaciers?
Glaciers are found in Arctic areas, Antarctica, and on high mountains in temperate and even tropical climates. Glaciers that extend in continuous sheets and cover a large landmass, such as Antarctica or Greenland, are called ice sheets. If they are similar but smaller, they are termed ice caps.
What are the two major types of glaciers?
There are two main types of glaciers: continental glaciers and alpine glaciers.
What are the 3 stages of a corrie?
- Three or more corries are eroded backwards into the same mountain.
- The ice steepens the back walls through plucking.
- Abrasion deepens the hollows.
- Freeze-thaw weathering creates a jagged peak.
- Where corrie sidewalls meet they form arêtes (knife-edge ridges).
- With a pyramidal peak in the middle.
Which way do drumlins point?
Drumlins are generally found in broad lowland regions, with their long axes roughly parallel to the path of glacial flow. Although they come in a variety of shapes, the glacier side is always high and steep, while the lee side is smooth and tapers gently in the direction of ice movement.
What do drumlins tell us?
Drumlins are typically 250 to 1,000 meters long and between 120 and 300 meters wide. That is, since ice flows in laminar flow, the resistance to flow is frictional and depends on area of contact; thus, a more elongated drumlin would indicate a lower velocity and a shorter one would indicate a higher velocity.
How do drumlins indicate the direction of ice flow?
The majority of drumlins in a swarm have their highest elevation and blunter end pointing in an upstream direction, with the more gently sloping and pointed end, or tail, facing down-ice.
What kame means in English?
: a short ridge, hill, or mound of stratified drift deposited by glacial meltwater.
Where is kame found?
Kame terraces are frequently found along the side of a glacial valley and are stratified deposits of meltwater streams flowing between the ice and the adjacent valley side.
