Earth+Dynamics

=Understanding the Earth and what makes it dynamic.= The Earth is always changing. That is why it is dynamic. Dynamic literally means changing. Static means to stay the same. So how is the Earth dynamic? That is what you will learn, but think about it for just a minute. How did the mountains get where they are? Were they always there? Was the Delaware river always there? Was it always the same size? What happens to the landscape when a volcanoe erupts or the Earth quakes? If a river floods, are there any changes? How did the Grand Canyon get Grand? Do the continents always stay in the same place with the same shape?

**To get yourself started you will need to teach yourself:**

1. What is Pangea?

2. What is the Continental Drift Theory?

3. Find at least 6 pieces of evidence that supports this theory to include:
 * What is the name of the scientist who first proposed this theory?
 * How rock magnetism and sea floor age contribute to the theory
 * How was the theory first accepted and what changed as more evidence was found?

4. What are convection currents
 * Where are they found?
 * What role do they play in shaping the Earth's surface?
 * Where do they get their energy?

5. What is plate tectonics?
 * What is a plate?
 * What does tectonics mean?
 * What is a convergence zone?
 * What is subduction?
 * Why does subduction occur?
 * Where does subduction occur?
 * What happens to the landscape at subduction zones?
 * What happens to the landscape at a convergent zone where there isn't subduction?
 * What is a divergent zone?
 * What happens at a divergent zone?
 * What happens to the landscape at a divergent zone?
 * What is a mid-oceanic rift?
 * What causes a mid-oceanic rift?
 * What is a transform fault?
 * What happens at a transform fault?
 * Give examples and locations of each of the above.

6. What are earthquakes? 7. What causes and earthquake? 8. How do we record earthquakes and how do we measure how strong they are?
