Boundary Interactions
When continental plates converge, these result.
What are mountains?
When a transform boundary slips, this is the effect.
What is an earthquake?
This type of boundary is where the plates slide past one another.
What is transform?
This guy came up with the concept of continental drift.
Who is Alfred Wegener?
What is EM waves do not require a medium?
When oceanic plates diverge, this happens.
What is mid-ocean ridge building?
Pressure on magma under the lithosphere may cause these when an oceanic plate subducts under a continental plate.
What are volcanoes?
This type of boundary is where plates crash into one another.
What is convergent?
One of the lines of evidence to support continental drift is scratches that these caused on rock on continents that are no longer in polar regions.
What are glaciers?
This is the reason you see lightning seconds before you hear the resulting thunder.
What is visible light waves travel faster than sound waves?
What are rift valleys?
This is the cause of mountain building.
What is convergence of continental plates?
This is where plates move away from one another.
What is divergent?
These identical remains on different continents indicate that they were once together.
What are fossils?
This explains a rainbow.
What is refraction of visible light waves through water vapor?
When transform plates grind past each other, this happens.
What are earthquakes?
This is the cause of tectonic plate motion.
What is convection currents in the earth's mantle?
These type of boundaries cause the most severe earthquake activity.
What are transform?
These two landforms that are the same on different continents indicate that they were once together.
What are rock strata (mountains) and mineral deposits (coal seams)?
This explains an echo.
What is the reflection of sound waves?
These are two results of an oceanic plate subducting under a continental plate.
What are volcanoes and deep ocean trench formation?
This is the shape of rock formed at mid-ocean ridges.
What is pillow shaped?
This type of boundary results in mountain building.
What is convergent (continental)?
This is how Wegener described how the continents seemed to fit together.
What is like pieces of a puzzle?
What is all travel at the speed of light?
