| Question | Answer |
|---|---|
| A plate boundary, associated with a trench, where plates don't butt into each other, but rather, one (the downgoing plate) sinks beneath the other (overriding plate). | convergent boundary |
| A supercontinent that assembled at the end of the Paleozoic Era. | Pangea |
| A continental margin that is not a plate boundary. | passive margin |
| A plate boundary where two oceanic plates move apart by the process of seafloor spreading. | divergent boundary |
| A location at the base of the lithosphere, at the top of a mantle plume, where temperatures can cause melting. | hot spot |
| A plate boundary where one plate slips sideways relative to the other, but no new plate forms, and no old plate subducts. It is a vertical fault on which the slip direction parallels the Earth's surface. | transform boundary |
| A wedge-shaped mass of sediment and rock scraped off the top of a downgoing plate and accreted onto the overriding plate at a convergent plate margin. | Accretionary prism |
| A continental margin that is also a plate boundary. | active margin |
