C2.2: Rivers of Ice

Goals of last lesson

1. You can explain how a glacier is formed, using the following terms: precipitation, firn , basin, glacier (G87).
   
2. You know 3 kinds of moraines and the corresponding location in the glacier.

CHECK 2 & 4

1. Glacial portal

2. Terminal moraine

3. Glacier-fed river

4. Lateral moraine

5. Glacier

MORAINES

4

1. Firn basin

2. Glacier

3. Glacial Portal

4. Lateral moraine

You can explain how a glacier is formed, using the following terms: precipitation, firn , basin, glacier (G87).

Precipitation - Water (rain, snow or hail) from the athmosphere that falls on the Earth.

Firn - Crystalline, ice snow left over from previous seasons. (old snow)

Firn basin - A place high in the mountains where firn accumulates.

Today's goals

1. You can explain the differences in origin between a U-shaped valley and a V-shaped
   valley. 
2. You can relate the terms glacial tunnel, glacial portal and glacier-fed river to each other.
   
3. You can explain how the weathered material is carried by 4 different transporters (G83).
   
4. You can describe the relationship between the flow speed of the river and erosion.

V-shaped valley

caused by a river

U-shaped valley

caused by a glacier

U-shaped valley

Take GeoGuide number 83 in front of you.

You can relate the terms glacial tunnel, glacial portal and glacier-fed river to each other.

Let's go!

• Read the text at page 26/27 of your coursebook.
  
• Make exercises 5 - 9 of paragraph 2 at page 27 in your workbook.
• Read GeoGuide numbers 83.

Rules while working:

• You work alone and in silence.
  
• Raise your finger if you've a question.
