The layer of the earth that we live on
The Mohorovicic Discontinuity separates these two layers.
Which layer is plastic, and what does plastic mean?
What specific layer do the plates of the crust float on?
The state of matter of the layer that is under the most intense pressure.
When Pangaea split, where would you find Laurasia?
What is a continental shelf?
Which general type of plate boundary has subduction?
Why do transform boundaries create the most earthquakes?
Draw an example of oceanic-oceanic convergence and what forms as a result.
Where do most earthquakes occur?
What scale measures the size of the earthquake?
What does the 'intensity' of an earthquake refer to?
What is a seismogram?
Draw a piece of the earth. Mark a possible focus and epicenter.
Draw a simple volcano and label the magma chamber.
What two things are the magma of explosive eruptions high in?
What type of volano is most common in Hawaii?
Krakatoa would be considered what kind of volcano in terms of activity levels?
What is lapilli?
Scientist who studied seismologic data and found that the Earth's density varied.
When did Wegner believe that Pangaea was all one continent? (which era)
How is a scientific theory different from a 'regular' theory?
At what rate do most plates spread apart in terms of divergent boundaries?
How does Paleomagnetism support continental drift and the idea of Pangaea?

The real edge of a continent under the water
Convergent
The plates grind past each other, get stuck, build pressure, and release
Two plates colliding under water. Forms island arcs.

In current positions, metals in rocks do not point to a common north, but if you put them together, they do.
