§5.4 and more

Slide 1 - Diapositive

The next questions are about how the river shapes the landscape (p.86-87)
Important words: 
  • Erosion
  • Transportation
  • Deposition
  • Load
  • Sediment
The river picks up materials, and scrapes away the land.
The river brings rocks, sand and clay to another place.
The river leaves rocks, sand and clay behind.
The rocks, sand and clay that are transported by the river.
The rocks, sand and clay that are deposited by the river.

Slide 2 - Diapositive

Which processes happened at letters A and B?
Erosion
Transportation
Deposition
A
B

Slide 3 - Question de remorquage

Where to find it in your book?
On page 84 you can find the three most important processes in the river: erosion, transportation and deposition.

At letter A you see that sand it taken away: erosion.
At letter B you see that material is left behind: deposition.

Slide 4 - Diapositive

Look at the image and complete the sentence:

The river ............ the river bank away.
A
eroded
B
transported
C
deposited

Slide 5 - Quiz

Where to find it in your book?
On page 84 you can find the three most important processes in the river: erosion, transportation and deposition.

In the image you can see that sand is taken away: this is erosion.

Slide 6 - Diapositive

Look at the image and complete the sentence:

The river ............ sand.
A
erodes
B
transports
C
deposits

Slide 7 - Quiz

Where to find it in your book?
On page 84 you can find the three most important processes in the river: erosion, transportation and deposition.

In the image you can see that there is sand in the river. The river brings it to another place: transportation.

Slide 8 - Diapositive

What do you see in these two images? Combine with the correct word.
Sediments
Load

Slide 9 - Question de remorquage

Where to find it in your book?
On page 84 you can find the three most important processes in the river: erosion, transportation and deposition.

The load is the material that is transported by the river. You see that in the left image.
The sediments is the material that is left behind (deposited). You can see that in the right image.

Slide 10 - Diapositive

Look at the image. Rocks like this you'll find in the ............... of the river.
A
lower course
B
middle course
C
upper course

Slide 11 - Quiz

Where to find it in your book?
On page 84 you can find the three most important processes in the river: erosion, transportation and deposition.

This is the upper course. The rocks are too heavy to be transported to the middle course. The river slows down and deposits the heavy rocks first.

Slide 12 - Diapositive

Look at the image.

These rocks are left behind here. They are ..............
A
eroded
B
transported
C
deposited

Slide 13 - Quiz

Where to find it in your book?
On page 84 you can find the three most important processes in the river: erosion, transportation and deposition.

The rocks are deposited, left behind.

Slide 14 - Diapositive

Look at the image. It shows how a V-shaped valley is formed. Complete the sentence:

The river ........... the V-shaped valley.
A
eroded
B
transported
C
deposited

Slide 15 - Quiz

Where to find it in your book?
On page 84 you can find the three most important processes in the river: erosion, transportation and deposition.

The river takes away the sand and rocks, so the valley becomes deeper and deeper. Taking away materials = erosion.

Slide 16 - Diapositive

Read the text. Put the words in the correct places. 
1

deposited
erosion
transported
middle course
upper course
sediments
load

Slide 17 - Question de remorquage

Answer explanation
If the river flows quickly (in the upper course) there is a lot of erosion = rocks are picked up.
If the river slows down, the heaviest materials are left behind = deposition. This happens in the middle course.
The load = the materials that are transported by the river.
Sediments = the materials that are deposited by the river.

Slide 18 - Diapositive

Finish the sentence:

If the river flows fast (1) happens.
If the river flows slowly (2) happens.
A
1 = transportation 2 = deposition
B
1 = deposition 2 = erosion
C
1 = erosion 2 = transportation
D
1 = erosion 2 = deposition

Slide 19 - Quiz

Where to find it in your book?
On page 84 you can find the three most important processes in the river: erosion, transportation and deposition.

If the river flows fast, there is mostly erosion.
If the river flows more slowly, the river deposits materials.

Slide 20 - Diapositive

2
Look at the image. Make the correct combinations.
1
2
river flows fast
river flows slowly
erosion
deposition

Slide 21 - Question de remorquage

Where to find it in your book?
On page 87 you can see how a meandering river forms. You can also watch the video again (see Magister studywijzer).

In the outer bend the river flows more quickly: erosion happens.
In the inner bend the river flows more slowly: deposition happens.

Slide 22 - Diapositive

Look at the image. Where will an oxbow lake probably form soon?
A
1
B
2
C
3
D
4

Slide 23 - Quiz

Where to find it in your book?
On page 87 you can see how a meandering river and oxbow lake form. You can also watch the video again (see Magister studywijzer).

At number 1 the river can flow straight if there is high water. The river takes the short cut, and it leaves behind a large oxbow lake.

Slide 24 - Diapositive

The next questions are about erosion and are only for havo/vwo.
Important words: 
  • Abrasion
  • Hydraulic action
  • Attrition


These are all forms of erosion!
Rocks in the river, scrape over the river bed.
The water takes sand from the river banks.
Rocks in the river knock each other into smaller pieces.

Slide 25 - Diapositive

Make the correct combinations
Abrasion
Hydraulic action
Attrition

Slide 26 - Question de remorquage

Where to find it in your book?
On page 86 you can find more information about the different types of erosion.


Slide 27 - Diapositive

Look at the image. The river bank is eroded away.

Which type of erosion happened here?
A
Attrition
B
Abrasion
C
Hydraulic action

Slide 28 - Quiz

Which type of erosion happened here?
A
Attrition
B
Abrasion
C
Hydraulic action
