Key Ideas:
· There are two main processes of glacial erosion: Abrasion and Plucking, plus one main type of weathering: Freeze-thaw
· Valley glaciers are more effective at erosion than ice sheets.
Terms:
· Erosion
· Abrasion
· Plucking
· Freeze-thaw weathering
· Valley glaciers
· Ice sheets
Starter:
Revision/completion of work from last lesson
Tasks:
· Using H p100-101, complete task 2 from p101. Take about ½ side of your book for each diagram.
· On a separate page start a Glaciation Glossary
This should be a list of words/phrases and their meaning that we cover in this topic and updated each lesson.
The words/phrases you should have listed/defined by the end of the lesson is below (use H p100-101, the glossary on p259-261 and your own knowledge to write the meanings):
· Glaciation
· Glacier
· Valley glacier
· Ice sheet
· Pleistocene ice age
· Snow line
· Glacial erosion
· Abrasion
· Plucking
Freeze-thaw weathering
