plate boundries
what plate boundary is it when plates collide or smash together?
convergent boundaries
What is the crust of the earth?
The outer most layer of the earth.
When forming deep-trenches which way is the denser crust being pushed for this to form?
The denser crust is pushed down.
What term is the proceses that recycles the oceans floor by gravity pulling down oceanic crust?
Subduction
what are all the convergent plate boundary types?
convergent (oceanic vs oceanic )
convergent ( continental / continental )
convergent ( oceanic / continental )
What is the outer most layer of the composed of?

Is the outer most layer of the earth a solid, liquid, or gas?
solid
Which convergent boundary forms volcano mountains by the floor crust being pushed down into the mantle causing it to re-melt the crust?
Oceanic vs continental
What does sea-floor spreading do?
What boundary is when the plates move apart forming a rift valley?
Divergent boundary.
Oceanic crust vs Oceian crust
Oceanic crust vs continental crust
Which convergent boundary collides and forms mountains by the crust crumbling up?
continental vs continental
How does convection work?
Heat being transfered by the movment of fluids, liquids, and gasses.
What is a transform boundary?
When the plates slide-slip past each other?
Which are the less dense types?
Continental vs continental
Which plates move apart causing a rift-valley?
Divergent boundaries
What casues new crust to be formed on earth, and what is a Earthquake prone area?
Sea floor spreading causes new crust, and a earthquake prone area is somewhere you cant get earthquakes.
