Today's goals

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

You know 3 types of moraines and

the corresponding location in the glacier.

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.

V-shaped valley

caused by a river

Let's go!

• Read the text at page 26/27 of your coursebook.
  
• Make exercises 2, 3, 5 + 6 of paragraph 2 at page 26 in your workbook.
• Use GeoGuide numbers 86 & 87.

Rules while working:

• You work alone and in silence.
  
• Raise your finger if you've a question.
  
• Always read the exercise well before you ask your question.
