C3.1: CHILE QUAKES AND SHAKES

GOALS OF THIS LESSON

1. You can name the 3 types of movements tectonic plates can make.
2. You can explain the words epicentre, hypocentre and seismic gap in your own words.
3. You can describe the difference between continental and oceanic plates.
4. You can explain how trenches are formed in a subduction zone (GG 68).
5. You can explain in 3 steps how volcanoes are formed near a subduction zone.

You can name the 3 types of movements tectonic plates can make (GG 68).

Make 1 drawing in your notebook:

You can explain the words epicentre, hypocentre and seismic gap in your own words.

(GG 73 + Coursebook)

Drawing: Difference between epicentre and hypocentre

You can explain the words epicentre, hypocentre 

and seismic gap in your own words.

                                           (GG 73 + Coursebook)

Seismic gap

a place where no heavy earthquakes have occurred compared with the surrounding areas.

Differences between a oceanic and a continental plate

Continental plate:

- Thick, light and mainly

   granite.

Oceanic place:

- Thin, heavy and mainly

   basalt.

PLATEMOVEMENTS

You can explain how trenches are formed in a subduction zone (GG 68).

Formation of a trench

in a subductionzone

Long, deep and narrow depression

on the ocean floor caused by subduction.

You can explain in 3 steps how volcanoes are formed near a subduction zone.

Formation of volcanoes

in a subductionzone

1. An oceanic plate dives under a continental plate.

2. Deep inside the earth it's very hot and the plate starts to melt.

3. The magma finds a way through 

      the earth's surface and you have 

      a volcano.

HORSTS AND GRABEN

HORST AND

GRABEN

Open G79 + notebook:

1. Which platemovement 

    causes this landscape?

2. Explain: How is a Graben 

     formed?

3. Look for an example of this 

     landscape in Europe in the 

     atlas.

Situation

in

Chile

Let's go!

• Read the text at page 40/41 in your coursebook.
  
• Make exercises 4 to 6
• Use the atlas and G77, G78 & G80

Rules while working:

• You're allowed to work together with your neighbor (WHISPERING).

This is also the homework for the next lesson!
