Plate Techtonics Flashcards
3 Types of Plate Boundaries
Convergent, Divergent, Transform
Scientist that created the theory of continental drift
Alfred Wegener
What is broken into techtonic plates that move slowly over the atmosphere
The Lithosphere
What is the lithosphere broken into
Techtonic Plates
What layer are the convection currents in
The Athenosphere
Hot material
Rises
Cool material
Falls
Convergent arrows
Towards each other
Divergent Arrows

Transform arrows
Sliding past each other
What can form from a convergent boundary ocean to ocean
Deep ocean trench
Volcanic island arc
What can form from a convergent boundary ocean to continent
Trench
Volcano
What can form from a convergent boundary continent to continent
Mountain
What can form from a divergent boundary ocean to continent
Mid ocean ridge (seafloor spreading)
What can form from a divergent boundary continent to continent
Rift valley
True or False: youngest crust is in the middle during seafooor spreading
True
What can form from a transform boundary
Earthquake
Convergent ( do handshake )
Collide
Divergent ( do handshake )
Divide
Transform ( do handshake )
Slide
Which boundary: plates can push up ti form mountains
Convergent
Which boundary: new seafloor is formed when magma rises to the surface between two plates
Divergent
Which boundary: subduction
Convergent
Which plate will subduct
The more dense. Pulling towards the core - the most dense
