Remembering Loma Prieta

What is the San Andreas fault?

 

 

How did the plates cause the earthquake?

 

 

Can you think of other examples where there is a strain between two things that results in a violent release?

 

 

Earthforce in the Core

Draw a diagram of the layers of the Earth. Label the inner core, outer core, mantle, lithosphere, and crust, which is the upper part of the lithosphere.

 

 

 

 

 

 

Which layer are the plates in?

 

 

Which layer do the plates "float" or move on?

 

 

How do you think the moving plates affect the layer of earth above them?
