When Glaciers Erode
Leftovers
100
These form where snow exists year round.
What is a Glacier?
100
This pulls snow and ice downhill causing glacial movement.
What is gravity?
100
Blocks of ice that break off of glaciers into the open water.
What is an iceberg?
100
Glaciers leave behind these long rows of till when they melt.
What is a Moraine?
100
This is a random large boulder left behind by a glacier.
What is an erratic?
200
Snow and Ice tend to melt when they move downhill and dip below this.
What is the snowline?
200
When glaciers go over slopes the brittle ice on the surface cracks.
What is a Crevasse?
200
Glaciers slide across rocks leaving these behind.
What are striations?
200
This process could cause rocks to fall on top of a glacier.
What is Frost Wedging?
200
An elongated upside down canoe-shaped hill formed by retreating glacial ice.
What is a Drumlin?
300
Glaciers can exist at the equator because of this.
What is High Elevation?
300
A slippery, slushy mixture of sediment and water is created. This slippery mixture causes glaciers to slide along.
What is Basal Slip
300
When glaciers grab rocks and carry them along.
What is plucking?
300
We used corn starch and water to model this type of glacial movement.
What is Plastic Flow?
300
When water flows underneath a glacier and deposits sediments this is formed.
What is an esker?
400
This continent is almost completely covered by glaciers.
What is Antarctica?
400
The kind of summer that allows a glacier to grow.
What is a cool summer?
400
GPS stakes lined up in a row.
What is a means of measuring glacial movement?
400
This valley shape is created when a valley glacier melts.
What is a U shaped Valley?
400
Melting ice and snow pooled and formed these small lakes.
What is a Kettle Lake?
500
Greenland is covered by this type of glacier.
What is a continental Glacier?
500
Ice Crystals in the glacier are compressed and squeeze slowly down, around, and over each other.
What is Plastic Flow?
500
When icebergs are born.
What is Calving?
500
The Himalayas of Asia, the Alps of Europe, and Alaska have this type of glacier.
