PLATE TECTONICS AND THE EFFECTS ON EARTH

8TH

What is Pangaea? What evidence do we have to claim the

theory of Pangaea? Fossils Climate Rocks

If the plates are moving, then why don’t we fall into magma, or all the water boil away?

Is there something holding the water?

What are the plates and crust made of? What are the 2 layers called that make

up the plates?

How are they different?

What happens at plate boundaries? What different ways can plates move?

Divergent, convergent, sliding What is subduction? Why do the plates move?

Which waves do the most damage and why?

How do we measure earthquakes and vibrations from the earth?

How do we locate where an earthquake happened?

An underwater earthquake can create a tsunami, but why is it so dangerous?

Describe what causes an earthquake? Where do earthquakes occur? What are the 3 types of faults?

Normal, reverse, and strike-slip As a fault moves what does it create?

Mechanical waves What are 3 types of seismic waves? How do we keep safe from earthquakes

What is a volcano? How does it affect the earth and plate

tectonics? Describe the different volcanoes and their

properties Shield- start at bottom and build up Cinder cone- created by gasses and don’t last

long Composite- steep side that can explode Fissure- liquid lava flows free, cover lots of area

As a volcano erupts, what is the most dangerous part?

describe the historical development of evidence that supports plate tectonic theory;

relate plate tectonics to the formation of crustal features.

interpret topographic maps and satellite views to identify land and erosional features and predict how these features may be reshaped by weathering.

Review superposition and how plate movements effect it.
