A large mass of ice that moves slowly over land.
What is a glacier?
100
They are made when more snow falls then melts
How are continental and valley glaciers made?
100
Continental
What is one type of glaciers?
100
true
Continental glaciers are larger than valley glaciers.
100
ice ages are a period of time when a continental glacier cover large parts of the earth.
What is an ice ages?
200
This is a mixture of sediments a glaciers deposits on the surface.
What is a till?
200
When a glacier melts it deposits sediment.
When a glacier melts what dose it deposit?
200
a valley glacier
What is another type of glaciers?
200
False.
All of North America was covered by a continental glacier in the last ice age.
200
No they move in all directions.
do continental glaciers move in only one direction?
300
A ridge formed at the end of a glacier.
What is a moraine?
300
1. plucking 2. abrasion
What are the 2 processes by which glaciers erode the land?
300
false! they can even move very large boulders!!
can plucking only move small stones?
300
no they move in a surge.
do valley glaciers move in one direction?
400
A kettle is a small depression formed by a chunk of ice when it malts.
What is a kettle?
400
GLACIAL EROSION: many rocks remain on the bottom of the glacier, and the drags them across the land. abrasion and it gouges and scratches the bedrock. GLACIAL DEPOSITION: deposits the sediment it eroded from the land, creating various landforms.
What is the difference between glacial erosion and glacial deposition?
400
Yes you can. people can melt the inside of glaciers and you can walk in side them.
can you go in side a glacier?
400
when the glacier gets to about 40 to 30 meters down.
when dose gravity start to pull a glacier down?
500
A long mound of till that is smoothed in the direction of the glaciers flow.
What is a drumlin?
500
Many rocks remain on the bottom of the glacier, and the glacier drags them across the land.
How dose abrasion affect bead rock?
500
Yes they are.
Are glaciers moving things?
500
when the glacier melts.
how dose glacier deposit occur?
