Glaciers advance when the weight of the new snow that piles on top of the glacier gets heavy enough to push it downhill.

How do glaciers move rocks?
Glaciers advance downhill on a thin film of glacial meltwater produced by heat from friction of the moving glacier melting sub-glacial ice. This is how they 'slide' but there are other ways of advance like laminar flow where individual layers of ice-pack slide over one another.
When do glaciers advance downward causing further erosional landforms?
During times of excess precipitation when the weight of accumulated snow makes them heavier. They also move by gravity.
What are two kinds of glaciers and how are they different?
The two different glaciers are valley and continental glaciers and they are different because continental glaciers are the largest, and valley glaciers are on the top of mountain peaks.
What planet has glaciers?
Earth has Glaciers
What are the different types of glaciers?
Ice Sheets Ice Shelves Ice Caps Ice Streams/Outlet Glaciers Icefields Mountain Glaciers Valley Glaciers Piedmont Glaciers Cirque Glaciers Hanging Glaciers Tidewater Glaciers
What are two ways in which glaciers erode Earth's surface?
When glaciers form they scrape earth's surface as they advance. Also when glaciers melt it deposits the sediment it eroded from the land creating various land forms.
Where do glaciers depost the earth and rock as they move forward and advance?
Glaciers often push earth and rock from beneath themselves as they move forward. Many natural lakes were formed by glaciers carving the earth as they passed.
3 facts about glaciation?
glaciers move with tremendous force, glaciers advance and retreat, and last but not least, they covered all of Canada and some of New York city :)
What are moraines and drumlins created by?
When glaciers advance or retreat, the sediments left behind create a moraine. Drumlins are created by the flow of glaciers that mold sediment into streamlined, elongated hills.
What is the term for any long period of time during which glaciers advance and cover large areas of the earth surfaces?
Ice age

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.
Did continental and valley glaciers advance during the ice age?
The glaciers advanced during the last glaciation, but they also advanced to some extent during the so-called "Little Ice Age" about 400 years ago. They withdrew as it started to become warmer about 200 years ago.

The two different glaciers are valley and continental glaciers and they are different because continental glaciers are the largest, and valley glaciers are on the top of mountain peaks.
What planet has glaciers?
Earth has Glaciers
How is a continental and valley glaciers the same?
Continental glaciers are thicker and larger. Valley glaciers are formed on mountains; continental glaciers are formed on flat land.
