What is the plan for today?

REPEAT LAST TIME:

• C2.2: Rivers of ice

START OF A NEW PARAGRAPH

• C2.3: Catchment area of the Rhine

Rules during class

1. A maximum of one person is speaking.
   
2. Raise your finger or hand if you want to say something.
   
3. Phones are off or quiet and are in your bag
   
4. Always bring your books: Coursebook, workbook, notebook & chromebook.

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.

V-shaped valley

caused by a river

U-shaped valley

caused by a glacier

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

C2.3: Catchment area of 

the Rhine

Today's goals

1. You can explain the relationship between meanders and the flow speed in the Upper Plain
   (W9, W10, G90). 
2. You can explain in 3 steps how an oxbow lake is created (W11, G90).
   
3. You can use a map to show the watershed between two catchment areas (G120).
   
4. You can explain why the flow rate in summer is much lower than in winter (G120).

Let's go!

• Read the text at page 28/29 of your coursebook.
  
• Make exercises 1, 2, 3, 5 & 6 of paragraph 3 in your workbook.
• Read GeoGuide numbers 90/120/121.

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.

Homework for next lesson
