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 happens during isostatic rebound?
Post-glacial rebound (sometimes called continental rebound, glacial isostasy, glacial isostatic adjustment) is the rise of land masses that were depressed by the huge weight of ice sheets during the last glacial period, through a process known as isostasy.
How were Eskers and Kettle lakes formed?
They were created by glacial movement 10.000 years ago, in the last ice age.
What paleo climatic evidence for polar wandering?
Layers of glacial deposits are found at same place in sequence of rocksNote directions of glacial ice movement as indicated by striations or grooves in the rock
How do continental shelves form?
The continental shelves were developed in between the glacial periods as the ocean flowed over the continents forming shallow areas along the coasts. The continental shelves developed today were formed like 18000 years ago.
What is Characteristics of glacial movement?
A characteristic of glacial movement is movement depends on the balance between accumulation and wastage.
What is a characteristic of a glacial movement?
A characteristic of glacial movement is movement depends on the balance between accumulation and wastage.
What is the movement of glacial ice called?
[Glacial] flow
What are glacial striations?
It was a continental drift .
What happens when glacial erosion occurs?
U-shaped valleys are a result of alpine glacial movement. Bedrock is scoured and plucked by continental glaciers. A number of depositional features are a result of the movement and depositing of rock, sand and dust associated with glaciers.
Clues that support continental drifts?
glacial deposits
How do glacial deposits support continental drift?
crust
What force caused the movement of the continents from super continent to their present positions?
The reason is because of glacial desposits. The other reason is because of ice bergs and continental drift.
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 force cause the movement of the continent from one super continent to the present positions?
The reason is because of glacial desposits. The other reason is because of ice bergs and continental drift.
When does glacial movement begin?
Glacial movement starts near the tops of mountains and ridges when the snowfall is heavy enough to start sliding downhill.
How does glacial erosion begin?
Glacial erosion requires movement. Thus, glacial erosion begins as soon as the glacier starts moving.
