Plate Tectonics 1
Causes the movement of Tectonic Plates
What are Convection currents in the Mantle?
The outermost layer of the Earth.
What is the crust?
The core is mostly made out of this type of metal.
What is Iron?
Cracks that are made in the plates at a transform boundary line.
What are Faults?
The type of plate boundary Taiwan is on
What is a Convergent Boundary?
The layer of Earth that is made of mostly solid iron.
What is the Inner Core?
The area where two tectonic plates meet.
What is a Plate Boundary?
This forms when two continental plates with similar densities converge.
What is a mountain range?
This type of boundary is made when two tectonic plates collide
What is Convergent?
The African Rift Valley is formed at this type of plate boundary.
What is Divergent?
The layer that the tectonic plates float on.
What is the Asthenosphere?
A boundary where two plates slide along each other.
What is Transform?
The last earthquake wave to arrive at a location
What is the L or surface wave?
This type of fault has one part that slides DOWN lower than the other part.
What is a Normal?
This type of fault has one part that moves UP higher than the other.
What is Thrust or Reverse?
Used to measure the strength of earthquakes.
What is a seismograph?
Used to measure the movement of tectonic plates. (double jeopardy, add or deduct twice.)
What is Global Positioning System (GPS)?
This hardens to form new rock at mid-ocean ridges.
What is Magma?
This type of fault usually occurs because of compression.
What is a Reverse or Thrust?
The raising of a rock layer.
What is Uplift?
He developed the theory of continental drift.
Who is Alfred Wegner?
The theory that the earth's surface is broken up into large pieces that float on top of the asthenosphere.
What is The Plate Tectonic Theory?
The type of tectonic plate boundary that sometimes has a subduction zone.
What is a Convergent Boundary?
The stress that stretches a rock layer.
What is tension?
