Plate Tectonics | Drifting Continents | Forces in the Earth's Crust | Earthquakes and Seismic Waves |
---|---|---|---|
What is seismic waves?
Waves released from an earthquake...
|
What is Pangaea?
Wegner thought that all the continents were once joined together in one large landmass he called...
|
What is compression?
What force in the Earth's crust squeezes to make the crust thicker and shorter?
|
What is earthquakes?
What is the shaking and trembling that results from the movement of earth's plates...
|
What is divergent boundary?
At which boundary do 2 plates pull apart...
|
What is continents move in opposite directions?
What did Wegner think happens during continental drift....
|
What is fault?
When enough stress builds up in rock, the rock breaks, creating a...
|
What is the focus?
This is the area beneath the earth's surface where rock that was under stress begins to break or move...
|
What is mountains?
What type of land-forms do convergent boundaries make?
|
What is no, his colleagues laughed at him and said he was crazy, as he had no way of proving how it happened.
Was Wegner's hypothesis received very well? Why not?
|
What is stress?
This force acts on a rock to change its shape and form...
|
What is p-waves, s-waves, surface-waves?
List the order of seismic waves as released by an earthquake...
|
What is convection currents in the mantle cause the earth's plates to shift and move which causes unrest on the surface.
Describe the Theory of Plate tectonics and how they occur (the mechanism that causes them)...
|
What is climate or the continents fitting together like puzzle pieces.
Besides fossils, name another piece of evidence for continental drift..
|
What is strike-slip fault?
In this type of fault, rocks on either side of the fault slip past each other side-ways...
|
What is seismograph? Where plate boundaries meet.
Geologists use what in order to locate an earthquakes epicenter? Extra point for explaining where earthquakes happen the most?
|
What is oceanic crust is thinner and less dense than continental crust which is thick and dense. This is important because oceanic crust will subduct under continental crust.
How does the density of oceanic crust differ from continental crust? Why is this important?
|
What is tropical plants and fossils of animals who are only able to survive in particular climates were found scattered across all of the continents.
Explain the use of fossil evidence to prove that continental drift is true and not a theory...
|
What is the Law of Conservation of Energy?
What is the law that describes the following situation:
The energy that is released from earthquakes is absorbed by the earth and transferred into various forms like heat, sound, and the destruction of the earth and materials on the surface. |
What is surface waves, although they travel more slowly, their amplitude is much greater.
What is the most destructive wave? Extra point for explanation of why?
