Plate Tectonics
Who discovered that that the world was a giant land mass and slowly drifted in to wha it is today
Alfred Wegner
Pangea
Which plate boundary is where two tectonic plates collide or come together?
convergent
What is the interaction at a convergent boundary?
collision
Which layer of earth consist of liquid iron and nickel?
outer core
What was the main evidence for Wegener's theory of Pangea?
The land masses fit like a puzzle
What is the super continent called
Pangea
Which plate boundary is where two tectonic plates separate and can form underwater mountain systems by magma rising up from the mantle?
divergent
What is the interaction at a divergent boundary?
spreading
Which layer of earth has the most mass or the largest?
mantle
What was Wegener's main evidence for continental drift theory?
Fossils found on different land mass
What is the crust in the top part of the mantle
Lithosphere
Which plate tectonic boundary is where two tectonic plates slide past each other and create earthquakes?
transform
What is the interaction at a transform boundary?
slip
Which layer of earth is the hottest and solid iron and nickel?
inner core
What is the top part of the mantle?
Aesthenosphere
How do the plates move about
Surface currents in the mantle
What is it called when a more dense oceanic plate slides under a continental crust and creates trenches?
subduction
What boundary is located at a collision interaction?
convergent
Which layer of the earth is the second layer going down and consist of hot, molten rock
mantle
Which crust is the thinnest yet more dense?
oceanic crust
What is the theory that continents slowly drifted from the land mass that they are today
Continental Drift
Which plate boundary has no created land in any way?
transform
What boundary is located where the plates are spreading?
divergent
What is the correct order of the earth's layers from top to bottom?
crust, mantle, outer core, inner core
What is it called when a oceanic crust collides with a continental crust and slides underneath it to create trenches?
subduction
