What is the glacial period of history?
A glacial period is like the time of ice ages, when the most of the earth is covered in ice and snow.
Is the current Ice Age period the only time in Earth's history that massive glacial activity has shaped the land?
No: glacial activity occurs in all glacial phases of all Ice Ages, and we now see the results of the latest within the present Ice Age.
How do melting glaciers shape land?
When the glacier is formed the ice scratches the land. When the glacier recedes the ice will scar the earth. This is called glacial scarring.
What is a Periods of rapid glacial movement are referred to as?
Periods of rapid glacial movement are referred to as glacial surges. These events are characterized by a sudden increase in glacial velocity, resulting in the movement of large quantities of ice over short periods of time. Glacial surges can drastically reshape the landscape and contribute to changes in local ecosystems.
What is a large landmass that rises above an ocean?
Continents are large land masses that rise above an ocean. During Post-glacial rebound, these land masses rose after being depressed by huge ice sheets during the last glacial period. As the weight of the ice was gradually removed from the land, the land was slowly lifted and resurfaced.
What is the effects of glaciers on the land surface material?
Glaciers not only transport material as they move, but they also sculpt and carve away the land beneath them. A glacier's weight, combined with its gradual movement, can drastically reshape the landscape. Over hundreds or even thousands of years, the ice totally changes the landscape. The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial landforms.
What is the movement of glacial ice called?
[Glacial] flow
How does a glacier affects the land?
A glacier can completely reshape the land. As it is made of very heavy ice, this ice can erode surfaces from the debris and rocks that it carries and the amount of pressure it places on the surface beneath it during its movement.
Does the North Pole or the South Pole has no landmass?
They both have glacial land mass. Glacial land mass is essentially ice, so it can grow or shrink based on the climate cycle. The North Pole, as it is a point on the Arctic ice sheet, that floats on the Arctic Ocean. The South Pole has a landmass buried below the ice cap.
How do glaciers affect the surrounding community?
Glaciers not only transport material as they move, but they also sculpt and carve away the land beneath them. A glacier's weight, combined with its gradual movement, can drastically reshape the landscape. Over hundreds or even thousands of years, the ice totally changes the landscape.

How does glacial ice differ from regular ice?
Glacial ice is much more solid then regular ice. Glacial ice is also alot colder than regular ice. Glacial ice can also be up to 1/2 a mile thick. Glaciation is aan extremly powerful force. 2. Glaciation happend very recently in geologic terms and there has not been enough time for the glacial features to be worn away.
Is glacial ice different from regular ice?
Yes. Glacial ice is ice that has been compressed under great pressure and will react differently as it melts.
