Today, glaciers often are tourist attractions in mountainous areas. But glaciers are also a natural resource , and people all over the world use the meltwater that glaciers produce.
How are a glacier and a bulldozer alike?
A glacier moves very slowly downhill, creeping just an inch or two a day. Because it is very heavy, a glacier can push rocks along like a bulldozer . It can erode, or wear away, the sides of mountains, smooth off the jagged bits from rocks, and move giant rocks, called boulders, over tens of miles.
Why are glaciers known as natural bulldozers?
Also, water flows to the bottom of the glacier which makes it slide easier on the ground. Just like rivers, glaciers can erode the nearby land and transport a lot of material. Sometimes glaciers are referred to as “nature's bulldozers” because they can completely modify the landscape through these processes .
What is bulldozing in geography?
Bulldozing is when rocks and debris, found in front of the glacier, are pushed downhill by the sheer force of the moving ice . Rotational slip is the circular movement of the ice in the corrie.
What does glacier mean?
A glacier is a large, perennial accumulation of crystalline ice, snow, rock, sediment, and often liquid water that originates on land and moves down slope under the influence of its own weight and gravity.

Which is the largest glacier in the world?
Lambert Glacier is the largest and fastest-moving glacier in the world. Lambert Glacier, Antarctica, is the biggest glacier in the world.
Is glacier ice safe to drink?
It's not advisable to drink glacier water , even if the water appears clean. It could be contaminated by organic or inorganic pollutants or even a microscopic parasite. So, anything can happen when one consumes melted glacial water. One could get sick immediately or after a couple of weeks or months.
What are the negatives of glaciers?
- Flooding caused by a glacier. Although it is not uncommon for a glacier to have a small lake of meltwater near its terminus, extreme melting or unusually fast melting can cause these lakes to overflow their barriers and cause flooding downstream. ...
- Avalanches from glaciers. ...
- The threat of icebergs.
What are 3 main types of glacial erosion?
Glacial erosion involves the removal and transport of bedrock or sediment by three main processes: quarrying (also known as plucking), abrasion, and melt water erosion .
What are 2 types of glacial erosion?
- Abrasion – as the glacier moves downhill, rocks that have been frozen into the base and sides of the glacier scrape the rock beneath. ...
- Plucking – rocks become frozen into the bottom and sides of the glacier.
How is Arete formed?
An arête is a thin, crest of rock left after two adjacent glaciers have worn a steep ridge into the rock . A horn results when glaciers erode three or more arêtes, usually forming a sharp-edged peak.
What is the smallest glacier in the world?

What are the two types of glacier?
Glaciers are often called “rivers of ice.” Glaciers fall into two groups: alpine glaciers and ice sheets . Alpine glaciers form on mountainsides and move downward through valleys. Sometimes, alpine glaciers create or deepen valleys by pushing dirt, soil, and other materials out of their way.
