Summary

Pay attention, so you are ready for the test

learning goals §1.1

• You know the differences between a young and an old mountain range.
• You understand how mountains can develop from ocean floor and volcanism.
  
• You can recognize fossils and the igneous rock on a photo.
  

Mountain formation

• Plates colliding
• Vulcanism

Ardennes

• old mountains 
  
• worn-down peaks 
  
• low height differences 
  

Hymalayas

• young mountains
  
• high sharp peaks
  
• deep valleys
  

Learning goals §1.2

• You know the difference between mechanical and chemical weathering and how weathering goes.
• You understand why the climate influences the nature and speed of weathering processes.
• You can explain how caves originate from looking at a drawing.
  

Addition

• The way cracks form in rocks is through changes in temperature
  
• Heat expands materials
  
• This expansion breaks rocks
  
• These cracks are small

mechanical weathering

• By freezing and thawing of ice
• By vegetation, mainly their roots
  

Addition

• Roots make the process of chemical weathering faster
  
• Roots of plants contain small amounts of acid
  
• water running down the roots take a bit of acid with it
  
• This acid helps the process of dissolving rocks
  

Chemical weathering

• Some rocks react to water and oxygen
  
• Iron rusts
• Limestone (Kalksteen) dissolves in water
• This breaks down the rocks over time

Learning goals §1.3

• You know what mass movement is.
• You understand that weathering and erosion affect mountains, and that river gravel, sand and clay are formed.
• You can recognize a river valley and a glacial valley from features in a photo.

Learning goals §1.4

• You know how sandbanks, dunes and deltas are formed.
• You understand that sedimentation occurs in a plain and that after a long time, sedimentary rock is formed from the compressed sediments.
• From a photograph, you can name some of the characteristics of sedimentary rock.
