Chapter 2.4 7.1 7.2 (review)

Slide 1 - Diapositive

Weather and climate
What is the difference?

Weather is what is happening in the atmosphere at a specific place and time.
Climate is the average weather in a large area during a period of 30 or 40 years.


Slide 2 - Diapositive

Landscape zones are characterized by the vegetation  that grows there. 
Savannah: 
Clusters of trees, grass and shrubs
Tundra:
Moss, grass and shrubs
The vegetation is dependent on precipitation and temperature.

Slide 3 - Diapositive

A diagram of the average temperature and the average precipitation is called a climate chart.
Red line: the average temperature
Blue bars: the average precipitation


Slide 4 - Diapositive

Which climate?

Slide 5 - Diapositive

Which climate?

Slide 6 - Diapositive

Slide 7 - Diapositive

High density
low density
Polar region
New York city
Temperate zone

Slide 8 - Question de remorquage

Earth’s crust is always changing
Natural forces

Exogenic                          Endogenic

from the outside                       from the inside

weatering / erosion                             vulcanos/earthquakes

Slide 9 - Diapositive

Layers of the earth
Crust: layer we live on, solid and very thin. Made of rocks.

Mantle:
 thickest layer of the earth, liquid but also moveable. 


 

Slide 10 - Diapositive

Layers of the earth
Outer core: liquid also made out of nickel and iron. Cooler around 3000 - 4500 degrees C.

Inner core
: solid made out of nickel and iron. Very warm (4000 and 6000 degrees C.)


 

Slide 11 - Diapositive

We have two types of tectonic plates:

Oceanic plates:
  • Found under oceans, 
  • thin (up to 10 kilometres)     but heavier. 
  • Made of basalt.




Continental plates:
  • Found under continents, 
  • thick (up to 75 kilometres)     but lighter. 
  • Made of granite.

Slide 12 - Diapositive

Three different plate movements
  1. Plates move away from each other = divergent movement
  2. Plates move toward each other = convergent movement
  3. Plates slide alongside each other = transform movement

Slide 13 - Diapositive

Transform
* earthshakes
Earth plates slide past each other. That is not gradual, but difficult. Tension is built up. If there is too much tension, the plates will shoot to discharge the tension.
Heavy earthquakes are born.

Slide 14 - Diapositive

divergent
Two oceanic plates are moving away from eachother.
Because of the high pressure in the 
mantle, the magma rise up. 
When it comes into contact with 
seawater, the magma solidifies.
A mountain range is created on 
the sea floor.  --> mid-oceanic ridge

Slide 15 - Diapositive

convergent
  • When two continental plates collide with each other :
              continental plates (lighter) will push each other up.
               --> mountain range

Slide 16 - Diapositive

convergent
  • When an oceanic plate collide with a continental plate (subduction):
               the heavier oceanic plate will sink back in the mantle. 
               the lighter continental plate will rise up.
--> vulcanos
--> trench
--> mountains

Slide 17 - Diapositive

subduction?

Slide 18 - Diapositive

Ring of fire

Slide 19 - Diapositive

Natural forces change the earth's crust.
Natural forces that change the earth's crust from outside are called ......
A
exogenic forces
B
endogenic forses

Slide 22 - Question de remorquage

What causes the magma to flow around in the mantle?
A
The heat in the core of the earth
B
The heat of the sun's rays on the earth

Slide 26 - Diapositive

You can explain how a earthquake occurs.
Earth plates slide past each other. Because this is difficult, the tension between the plates is built up. If there is too much tension, the plates will shoot to discharge the tension.

Slide 27 - Diapositive

You can name the difference between a epi- and a hypocentre.
Earthquakes start in the Earth’s crust. The deepest point is called the hypocentre. The point on the Earth’s surface right above the hypocentre is called the epicentre. That is where you feel the worst tremors.

Slide 28 - Diapositive

You can name how the Richter scale works.


"Scale for measuring the force of an earthquake."

Slide 29 - Diapositive

How a tsunami is formed

Slide 30 - Diapositive

G 7  Switching scale level
local scale: local 

regional scale: part of a country, province or territory 
national scale: country ,
continental scale: continent ,                          Zooming in
global scale: the world .                                      
                                                                                        Zooming out





Slide 31 - Diapositive

Explain how a volcano forms in a subduction zone.
