Climate and landscape in the Pleistocene
Lesson goals:
1. Define Pleistocene and Holocene period (using the atlas)
2. Discuss dolmens
3. Review the two main ice ages (Saale en Weichsel)
Slide 1 - Tekstslide
Hunnebedden / Dolmens
In Drenthe there are no mountains or rocks. But hunebedden are made of huge stones. Where did they come from..? The answer is: from Scandinavia. About 200,000 years ago, during an ice-period, most of northern Europe including our country was covered by a thick layer of ice. The big boulders of which the hunebedden are made of have been transported to The Netherlands by slow moving ice-glaciers. Even today, digging in Drenthe's soil, smaller and bigger stones emerge.
Slide 2 - Tekstslide
What were 'hunnebedden' (dolmens) used for?
A
Shelter
B
Places to gather
C
Graves
D
Storage of food
Slide 3 - Quizvraag
What is another name for an ice age?
A
Pleistocene
B
glacial period
C
Holocene
D
interglacial
Slide 4 - Quizvraag
Saale Glacial
Slide 5 - Tekstslide
Saale Glacial
Ice covered large part of the Netherlands (HUN - line = Haarlem - Utrecht Nijmegen) DRAWING
The rest of the Netherlands was a polar desert (very cold)
Moraines formed because ice pushed material forward (glacial sediments) forming the Utrechtse Heuvelrug.
Slide 6 - Tekstslide
The ice reached no further than the HUN - line
Stuwwallen = terminal moraine
Keileem = boulder clay
Slide 7 - Tekstslide
Weichsel Glacial
Slide 8 - Tekstslide
Weichsel glacial
Ice covered Scandinavia
Most of the Netherlands was a polar desert
South Limburg had some vegetation on its hills
Wind-borne sand (dekzand) form the former North Sea covered the Netherlands.
Loess (löss) covered South Limburg
(DRAWING)
Slide 9 - Tekstslide
How could the wind-borne sand come from the former North Sea?
A
The water would wash the sand onshore
B
The sea water was stored in the ice caps
C
There was enough space
D
The wind blew very hard
Slide 10 - Quizvraag
Why was the lighter loess trapped in South Limburg? This is because
A
rivers carried it towards South Limburg.
B
there was enough sand left.
C
hills and vegetation trapped the loess.
D
the winds in this area were not very strong.
