The force/power behind the movements of tectonic plates is fueled by:
the process of how the heat in earth's core(s) is transferred along the upper mantle and asthenosphere layers.
the ages of rock close to and further away from mid-ocean ridges. What process causes this?
Along the mid ocean ridge, caused by seafloor spreading
Along which areas of earth's crust would convection currents most likely be found?
along plate boundaris
What type of tectonic plate movement is found along mid-ocean ridges?
divergent boundaries moving apart
What types of tectonic plate movement occur along ocean trenches?
convergent-move towards eachother
Which type of earth crust tends to be MORE dense? Why? Which is LESS dense? Why?
why, because water is pushing down on it and pushing more rock on it
less dense= continental
why, because their is nothing pushing it down on it so it is floating and less dense things float
Compare & contrast the thickness of BOTH continental and oceanic crust.
Divergent plate boundaries often create which type of crustal features?
rift valleys, ocean ridges, and seafloor spreading
direction of arrows in convection currents that would cause tectonic plates to CONVERGE and DIVERGE.

Alfred Wegener's Theory of Continental Drift. Which types of evidence did he use to help support his theory?
Alfred wegener had a theory on how the continents moved apart, he did not have any evidence about the theory. Later scientists discovered the idea of continental drift.
Describe the characteristics of igneous rock that forms along a mid-ocean ridge. Be sure to describe the texture, grain size, and rate of cooling in your description.
texture- something you would bake in an oven
grain size- course/fine
rate of cooling- course-slow
