test #2: plate tectonics

how do plates move?

on the athenosphere by convection

what happens when plates move?

earthquakes

what are the three types of plate movement?

convergent forces- head on collision

divergent forces- pull apart

transform boundary- two plates move in opposite directions

at convergent boundaries, the force of the two plates colliding usually creates what kind of zone?

subduction zone

what happens at a subduction zone+ characteristics?

one goes under the other

idk

give 1 world example of subduction zones

japan

what is a ridge zone+ give a world example

magma gets between plates+ makes ridge

Iceland

how do ferns and reptiles explain the theory of plate tectonics?

plants and reptiles don’t go in cold places

how do glaciers/ glaciation prove the theory of plate tectonics?

doesn’t make sense to have glaciers in hot places

how do minerals/ mountains prove the theory of plate tectonics?

same geology on continents close together

how does the puzzle fit prove the theory of plate tectonics

South America+ Africa fit like puzzle pieces
