Glacial Erosion Web Quest
You will be using the computers and websites to collect data. With this data you will be responsible for drawing 3
diagrams that explain
1. Glacial Abrasion
2. Glacial Plucking
3. Glacial Freeze-Thaw/Thermal Expansion
Goal: _____________________________________________________________________________________
Station 1: Glaciers (http://www.neok12.com/Glaciers.htm) Use this website for all of station 1.

(2)The definition of abrasion is “the act or process of damaging or wearing away something by rubbing”. Does
this definition make sense in terms of glacial abrasion? Why?
