Lesson 4

Goals

• Students know how an river originates
  
• Students can explain in their own words the three stages of the course of the river.
  
• Students can explain what sedimentation is and what is sedimented at each course of the river.

Homework

Explain what erosion is.

What three transport agents move weathering material?

What reliefs are there? Name + heights

What is the difference between an old and a young mountain range?

From source to mouth

• Source = Lake Toma, near the Oberalp
  Pass in Switzerland; the start of the river.
• Mouth = the Rhine reaches the North Sea;
  the end of the river.

Between the source and mouth

• The river looks for the easiest route down
• --> the flow bends
  
• This is called meanders
  

Get to work!

1. Read lesson 4 up to 'The profile of the Rhine'
2. Mark all the important sentences
   
3. M: 1a, 2, 3a, 3c, 4c, 4d, 4e, 4g & 4h
   H: 1a, 1b, 2, 3a, 3b, 3c & 4 (except 4f)
   V: 1, 2, 3 & 4
   
   

What is the flow rate?

Upper course: ?

Middle course: ?

Lower course: ?

What is the flow rate?

• Upper course: high flow rate
  
• Middle course: the water flows less quickly, but still quite fast
  
• Lower course: slow flow rate
  

Beginning of the river 

End of the river

Profile of the Rhine

• Which letter has the most weathering?
  
• Which letter shows the lowland?
  

A

B

C

Sedimentation

= when sand, mud, or other materials carried by water, wind, or ice settle and build up in a new place.

Profile of the Rhine

• Why does the letter C have the most sedimentation?

A

B

C

Drainage network Rhine

Delta's

• A delta is a piece of land created when a river deposits sediments.

Different kind of rivers

• Rain river: starting point is not high in the mountains, so no glacier water.
• The Rhine is a mixed river
• It starts in the mountains at high altitude, so it gets water from glaciers, but also of course from rain.

Design a River Journey Map

• In pairs: draw a map of a river from the mountains to the sea
• Include: source, upper course, erosion, waterfall, middle course, meander, sediment, delta, mouth.
• At least one example of erosion and one of sedimentation
• Tiny icons or drawings to show animals, people, or villages along the river
• Bonus Challenge:
• Name your river and write a short story or description of a drop of water travelling from the source to the sea.

Chat example

So?

• Where would erosion be strongest?
• Where would sedimentation happen?
• Why are cities often near the mouth of a river?

Goals

• Students can explain in their own words the three stages of the course of the river.
  
• Students can explain what sedimentation is and what is sedimented at each course of the river.

Explain what erosion is.

How do rivers originate?
