To conclude, we can say that tectonic plates are the major factor which provoke earthquake by this model we can affirm our hypothesis about tectonic plates.

-We observe many faults appening on the crust. It creates a relief that will became an ocean.

eed a plastic box, semolina and cacao powder

-We'll put it in the box in order to modelise faster the tectonic plates' divergent movements.

today , I'm going to illustrate convergence between two tectonic plates . 
To do so, we need chocalate powder and semolina and a transparent plastic box. 
We will  put a first layer of semolina and after a layer of chocalate powder and we will do this four times to modelise the earth surface.
then in order to show  wea  

divergent movement of tectonic plates,

 will pull away  the two sides of the box.
We can observe many faults in the crust. It creates a mountain . We conclude ,  that the  tectonic plates movements   provoke earthquakes.

Today, I’m going to show you a model of tectonic plates movements in order to find out how it goes underground !

To make it, I need semolina, cacao powder, a spoon, a clear plastic box and a handle. 

First, I have to pour the first layer of semolina and cover it with a layer of cacao powder and then repeat it 3 times. 

Then, I pull the walls of the box in order to see what happens when there is less pression on the walls. 

I observe some faults caused by the the distance between the walls, it’s easy to see them. 

To conclude, faults are caused by  

earthquakes at the surface of the earth.
