C2.2: Rivers of Ice

Goals of last lesson

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.

MORAINES

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.

Open paragraph 2,

we take a look at the

GeoGuidenumbers

We copy the blue words

from the text and we

put them in a drawing

Let's go!

• Read the text at page 26/27 of your coursebook.

Rules while working:

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

Finished? Make paragraph 1 + 2 of the list of knowledge and skills
