An argument is invalid if and only if all the premises is true and the conclusion is false.
We can test the invalidity of the argument by assuming all the premises are true and seeing whether it is possible for the conclusion to be false. If the conclusion is possible to be false, then, the argument is invalid.
A valid argument, on the other hand, is valid if and only if it is necessary that:
1) if all of the premises are true, then the conclusion is true
2) if all of the premises are true, then the conclusion must be true
3) it is impossible that all the premises are true and the conclusion is false.
I would say that plate tectonics shows what the origin of volcanic activity, earthquakes and mountains comes from their collision or subduction. Where two plates collide mountains can be formed (uplift), where subduction occurs then volcanic activity like in the circum-pacific belt occurs and where stresses build up in subduction or transform fault (like the San Andreas Fault) and are suddenly released, earthquakes are the result. Subduction is where the oceanic plate gets pushed under the continental plate.
