100
composed of both oceanic and continental.
What is 2 kinds of earth's crust?
100
the movement of S waves
What is a side to side motion?
100
compression fold that has the youngest rocks in the middle
What is an anticline?
100
boundaries that caused Pangaea to break apart
What are divergent boundaries?
100
located directly below the epicenter
What is the focus?
200
the outer core is thought to be liquid because it will not transmit these waves.
What are S waves
200
these 2 waves are body waves.
What are S waves and P waves
200
mountains created by compression.
What is folded mountains?
200
places where the crust is the newest
What are divergent boundaries?
200
causes deformation of the earth's crust
What is stress?
300
the most dense solid part of earth
What is the inner core?
300
the place on the surface of the earth where P waves arrive first.
What is the epicenter?
300
fault in which the hanging wall moves downward.
What is normal fault?
300
the energy that drives the movement of the tectonic plates
What is heat energy?
300
forces that can cause faults in the earth's crust
What are compression, tension and shearing?
400
the process by which the earths oceanic crust sinks back into the mantle to be recycled.
What is subduction?
400
seismic waves that move in a rolling motion along the earth's surface.
What are L waves?
400
fault in which the hanging wall moves over the footwall.
What is a thrust fault?
400
the charateristic that causes oceanic crust to subduct under continental crust
What is density?
400
the reason the earth is in layers
What is density?
500
movement in the mantle that causes the tectonic plates to move.
What is convection?
500
P waves changing direction as they move through the earth's core
What is refraction?
500
Formed when normal faults create valleys
What is rift valley?
500
boundaries where crust is recycled
What are convergent boundaries?
500
3 evidences for continental drift
What are fossil evidence, mountain chains/rock, glacier evidence or shape of continents
