The geological theory that states the pieces of Earth's lithosphere are in constant, slow motion.
What is plate tectonics?
200
Forces that slowly wear away features on Earth's surface.
What are destructive forces?
200
A collision between two pieces of continental lithosphere at a converging boundary produces this landform.

300
Most geologists think that the movement of Earth's plates is caused by this.
What are convection currents in the asthenosphere?
300
A collision of plates that have similar densities occur at this type of boundary, so that they buckle and fold.

Earth's outer most layer.
What is the crust?
300
Mountains formed by the folding of rock layers caused by compressive forces.
What are folded mountains?
400
One plate sinks underneath another plate.
What is subduction?
400
Forces that shape Earth's surface by building up mountains and landmasses.
What are constructive forces?

Scientists think that convection currents flow here.
What is the Asthenosphere?
500
A place where two plates slip past each other, moving in opposite directions.
What is a transform boundary?
500
Mountains made of huge blocks of rock separated from surrounding rock by faults.
