Which type of wave cannot travel through the Earth?
Surface Waves
What kind of plate boundary is formed when material rises in the mantle?
Divergent
The mantle is a solid, but lava and magma come from the mantle and they are liquids. What is needed in order to help the solid mantle melt and become lava?
Water
What are the two main differences in oceanic and continental crust?
Oceanic crust is thinner and more dense while continental is thicker and less dense
The magnetic polarity reversal of the outer core provides evidence for what kind of plate boundary?
Divergent Plate Boundary
What layer of the Earth can S waves not travel through and why?
Outer core- its a liquid
What kind of plate boundary is formed when mantle material cools and sinks back down?
Convergent
The build up of what force leads to earthquakes?
Friction
What is the name of the process that describes how the earth went from having no layers to having layers.
Planetary Differentiation
When oceanic plates converge with continental plate the oceanic plate goes under the continental. Why is this?
The oceanic plate is more dense than the continental plate
Which type of wave is the most destructive?
Surface Waves
If the mantle could no longer be heated up to convect- what would happen to plate tectonics?
The tectonic plates would stop moving
