Along what types of tectonic plate boundaries
are volcanoes generally found? Why?

Divergent plate boundaries because the separating of the tectonic plates allows for the lava to push its way through the rift and escape to Earth's surface.

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.
