Learning

Slide 1 - Tekstslide

Learning goals
− You know which forms of weathering there are.
− You understand how ice, plant roots and changes in temperature cause weathering.
− You know the types of weathered material are and how they differ in size.
− You understand how the transport of weathered material can cause erosion.

Slide 2 - Tekstslide

Learning goals

− You know in which ways weathered material can be moved.
− You understand why a river is better at sorting weathered material than a glacier, and the wind can do it even better.
− You understand why there is much sediment at the end of a glacier.

Mechanical weathering

Slide 9 - Sleepvraag

Weathered material
The river brings material from the higher reaches to the middle and lower reaches. 
This material decreases in size the further you go.

Boulders, rocks, gravel, sand, clay. 

Slide 10 - Tekstslide

Erosion
Rivers grind away the landscape. The weathered material in rivers bumbs into the sides and scrapes the sides away, like sandpaper does.

no

Slide 18 - Quizvraag

Weathering due to water freezing in the cracks of the stone is called
A
biological weathering
B
frost weathering
C
chemical weathering
D
weathering due to the temperature of stone

Slide 19 - Quizvraag

The glacier makes a U-shaped valley
The glacier brought rocks from Scandinavia to The Netherlands
The glacier picks up rocks
The glacier melts and leaves rocks behind

Slide 31 - Sleepvraag

This picture is taken in Canada. Explain how this landscape is formed. Use the words 'erosion' and 'weathering'.

Slide 32 - Open vraag

2 hoofdsoorten verwering.
Elke hoofdsoort kent weer verschillende voorbeelden.
Chemische verwering

Het gesteente valt uit elkaar doordat de chemische structuur verandert.

Waardoor: 
- Oplossen van gesteenten in zuur (grond/regen)water
Fysische verwering
(mechanische verwering)

Het gesteente valt uit elkaar, maar behoudt de zelfde structuur.

Waardoor:
- grote temperatuurverschillen,
- vorst
- wortels van planten
- plotseling drukverschil
