The biggest types of glacier are called continental ice sheets and ice caps. They often totally cover mountains. Glaciers that flow down a valley are called valley glaciers.

Which is the world’s second largest glacier?
Closeted in a lap of an archetypal U-shaped glacier valley with the Saltoro Hills to the west and Karakoram Range to the east in the Ladakh District of the state of Jammu and Kashmir, the Siachen Glacier is the longest (76 km) glacier in Himalaya and the second longest glacier in the world outside the Polar Regions.
What are the three main types of glaciers?
Glaciers are classifiable in three main groups: (1) glaciers that extend in continuous sheets, moving outward in all directions, are called ice sheets if they are the size of Antarctica or Greenland and ice caps if they are smaller; (2) glaciers confined within a path that directs the ice movement are called mountain …
What are the components of glacier movement?
Glaciers in temperate zones tend to move the most quickly because the ice along the base of the glacier can melt and lubricate the surface. Other factors that affect the velocity of a glacier include the roughness of the rock surface (friction), the amount of meltwater, and the weight of the glacier.
What is the most important erosional agent in deserts?
Running water is still the most important agent of erosion in the desert as far as creating the desert landscape, but wind also plays a role, not as important as water in the long run, but you might say that wind sort of fine tunes the landscape that’s created by the running water in the first place, so we can look at …
What are the 2 main types of glacier?
There are two main types of glaciers: continental glaciers and alpine glaciers. Latitude, topography, and global and regional climate patterns are important controls on the distribution and size of these glaciers.

What is the most powerful erosive force?
THE FORCES OF EROSION: WATER, GLACIERS, AND WIND
But the most powerful erosive force on earth is not wind but water, which causes erosion in its solid form — ice-and as a liquid. Water in its liquid form causes erosion in many ways. Streams — from tiny creeks to huge rivers — carry tons of eroded earth every year.
Which country has no glaciers?
Without glaciers, one resident quipped, Iceland is “just land.”
What is the oldest glacier in the world?
How old is glacier ice?
- The age of the oldest glacier ice in Antarctica may approach 1,000,000 years old.
- The age of the oldest glacier ice in Greenland is more than 100,000 years old.
- The age of the oldest Alaskan glacier ice ever recovered (from a basin between Mt. Bona and Mt. Churchill) is about 30,000 years old.
Why are glaciers so blue?
Glacier ice is blue because the red (long wavelengths) part of white light is absorbed by ice and the blue (short wavelengths) light is transmitted and scattered. The longer the path light travels in ice, the more blue it appears.
What is a growing glacier called?
The processes and features caused by or related to glaciers are referred to as glacial. The process of glacier establishment, growth and flow is called glaciation. The corresponding area of study is called glaciology.
What causes glaciers to move?
Glaciers move by a combination of (1) deformation of the ice itself and (2) motion at the glacier base. … This means a glacier can flow up hills beneath the ice as long as the ice surface is still sloping downward. Because of this, glaciers are able to flow out of bowl-like cirques and overdeepenings in the landscape.
How are glaciers named?
A glacier is a huge mass of ice that moves slowly over land. The term “glacier” comes from the French word glace (glah-SAY), which means ice. Glaciers are often called “rivers of ice.”
