boundaries
The place where two plates meet. It is where most deformation occurs
What is a boundary
The vibration of the earth produced by rapid energy release
What is an earthquake
The top layer of the earth.
What is the crust
The theory that the continents are drifting
What is continental drift?
waves of energy that travel through rock released by earthquakes
What is seismic waves
When tectonic plates move toward each other and collide. It is where one plate sinks below the other. It is also where two continental plates meet pushing against each other
convergent boundaries
It is a place within Earth along a fault at which the first motion of an earthquake occur
What is Focus
The innermost layer of earth.
What is the inner core
Developed the continental drift theory.
Who is Alfred Wegner?
movement of matter that results from differences in density
What is convection current
It is where two tectonic plates move away from each other. An example of this boundary exists between the North America and Eurasian plates.
Divergent Boundaries
Where do most earthquakes happen?
What is at or near the tectonic boundaries. The movement and interaction of the plates causes the crust to break into different types of faults. Earthquakes happen along these faults
Put the layers of earth in order from least dense to most dense.
What is crust (least dense contains silicates), mantle, and core (mostly iron)
Theory that the Earth surface is made up of giant moving slabs.
What is plate tectonics
the process by which one tectonic plate is pulled beneath another
What is subduction
When two tectonic plates move past one another in opposite directions it is called a transform boundary. What is the name of a transform boundary between the North American plate and the Pacific Plate
What is the San Andreas Fault
A massive wave created by an underwater earthquake
What is a Tsunami
A solid thin layer of mantle material below the lithosphere. Rock is less rigid and is more putty like
Asthenosphere
What are the three processes that cause tectonic plates to move across the surface of the Earth
What is mantle convection, ridge push and slab pull
These waves cannot travel through the Earth's outer core because they can not travel through liquid
What is S waves
What are three features associated with convergent boundaries?
What is folded mountains, volcanoes, and ocean trenches.
what are the seismic waves that pass through the earth's interior generated by earthquakes and sometimes explosions.
What are P waves and S Waves
The outermost physical layer of Earth. It contains the crust and upper mantle
What is lithosphere
What results in the formation of the sea floor?
What is sea floor spreading?
Fault block mountains and rifts are associated with these boundaries
What is divergent boundaries
