Recap chapter 1

Earth in Motion

Today 

• Recap of all important terms for the test
• Go to work

Learning goals

• You can point out the different layers from which the earth is build up and tell how the earth is build up from core to crust
• You can explain how a convection current works
• You can explain the difference between a continental crust and oceanic crust
  
• You can name the different plate movements

Plate tectonics

The earth consists of several plates. The plates move from each other separately. We call this plate tectonics

Plate tectonics is driven by the convection currents. Explain what a convection current is.

What is the correct order of the different layers of the earth from inside to the outside?

1. Earth's mantle, Earth's inner core, Earth's crust, Earth's outer core
2. Earth's crust, Earth's mantle, Earth's outer core, Earth's inner core
3. Earth's inner core, Earth's outer core, Earth's mantle, Earth's crust
4. Earth's outer core, Earth's inner core, Earth's mantle, Earth's crust

The Earth's crust

There are two types of Earth's crust. Both types have their own characteristics

• Continental crust
• Oceanic crust

The continental crust is heavier than the oceanic crust

1. True
2. False

Continental crust

Oceanic crust

Thin layer

Below oceans

Located below land

Thick layer

Dense and heavy rock (basalt)

Lighter rock (granite

What are the names of the three plate movements that we know? Write down the geographical name + the way it moves

Learning goals

• You can name the different plate movements and the corresponding consequences
• You can explain the difference between the hypocentre and the epicentre
• You can explain why the consequences of earthquakes in rich and poor countries can differ
  
• You can explain how a tsunami forms

Subduction

Divergent border

Transform border

Convergent: two continental plates

Heaviest earthquakes

Mid Oceanic ridge

Heavy earthquakes

Shield volcanoes

Mountain formation

Strato volcanoes

No volcanism

Trenches

Which statement is true?

1. The hypocentre is the place below the earth surface where the earthquake started
2. The epicentre is the place below the earth surface where the earthquake started

Is the damage due to an earthquake higher in poor or in rich countries. Explain why

In the picture you can see the way in which a tsunami develops.

One thing we need for a tsunami to develop, is an earthquake at the ocean floor. 

What is the correct order in which a tsunami develops?

1. Water travels fast in deep sea, earthquake at ocean floor, shallow coastal zone creates a huge wave
2. Earthquake at ocean floor, shallow coastal zone creates a huge wave, water travels fast in deep sea
3. Earthquake at ocean floor, water travels fast in deep sea, shallow coastal zone creates a huge wave

What is the name of a volcano that looks like this?

We have just seen a strato volcano. Name two characteristics of this type of volcano.

What is the name of a volcano that looks like this?

We have just seen a shield volcano. Name two characteristics of this type of volcano.

What is the name of this region?

What are you going to do

• Finish the assignments in Buitenland > many missing assignments, so make sure you've answered them 
• Start studying for the test: make a summary, learn the summary, practice with the key terms, ask your final questions :)
