Next week the test

I will give you the candy bars next week, because I had no time to go to the supermarket

What is the main activity of tourists when they go to the Alps?

Notes

When it is bold, it is really important!

The Lötschental

The Lötschental is an area with a lot of relief (hoogteverschillen) and at the top a glacier.

Glacier: a large body of ice that slowly moves down a slope

High mountain

• Mountain range with peaks that are higher than 1,500 m
• Most of the mountains in the Alpes are higher than 1500 m
  

Relief

• height differences in the mountains
  
• you see the differences with colours
  

Relief

• Green : Lowland 0 – 200 m
• Yellow:  Hills 200 – 500 m
• Light brown: Medium mountains 500 – 1500 meter
• Dark brown:  High mountains ranges above 1500 meter

Glacier

• A thick mass of ice created when snow on top of a mountain fails to melt
• This slides down slowly, under pressure 
  

Double-season

• Tourists visit the Alps the whole season
• In the summer: hiking and cycling
  
• In the winter: snowboarding and skiing

Compare the two maps. What do you notice?

First look carefully.

Compare the two maps. What do you notice?

Population density and relief

Elevation zones

Elevation zones = A vegetation zone on a mountain

Schrijf de vraag en het antwoord in je schrift.

1. Waarom groeit de bevolking?
2. Hoe verschilt de groei van de bevolking per land?
3. Waarom wonen op sommige plekken veel mensen?
4. Waarom wonen op sommige plekken weinig mensen?

Elevation zone = A vegetation zone on a mountain. Created by differences in temperature. From low to high:

• deciduous forest zone
  
• coniferous forest zone
  
• Alpine meadow = Above the tree line is the elevation zone where grass, herbs and low shrubs grow.
  
• Rocky zone = The elevation zone where the weather is so cold and the ground is so hard that there is almost no vegetation
  
• Perpetual snow
  

Zet de hoogtegordels op de juiste plaats in de tekening.

Hoogteligging 

Rule

The higher the colder
If you climb 1000 meters, it gets 6 degrees Celsius colder.

Explanation

Only when solar rays fall on the Earth's surface, they do give off their heat. As a result, the Earth's surface warms up and gives off heat itself now. The atmosphere is thus heated from below.

Altitude and temperature

High mountain range

• height belts
• Temperature:  -0,6 per 100 meter increase
