| Question | Answer |
| What features are associated with a ocean-ocean convergent plate boundaries? | volcanic island arcs (island chains) earthquakes subduction zones trenches |
| What features are associated with a continent-continent convergent plate boundaries? | volcanic arcs (on land) folded and faulted mountains trenches earthquakes |
| Which type of stress is associated with a divergent plate boundary? | tension |
| Which type of stress is associated with a convergent plate boundary? | compression |
| Which type of stress is associated with a transform plate boundary? | shearing |
| What is subduction? | The process of more dense plate sinking beneath a less dense plate during a tectonic collision |
| The "Ring of Fire" is located around which tectonic plate? | Pacific Plate (around the Pacific Ocean) |
| One of Alfred Wegener’s problems in explaining his Theory of Continental Drift was - | he lacked knowledge of the mechanisms that drive it |
| What drives or moves plate tectonics? | convection |
| A continental-oceanic boundary where plates collide is called a — | subduction zone |
| As you move away from a hot spot the age of the rocks get - | older |
| Compared to Earth’s continental crust, Earth’s oceanic crust is — | thinner and denser |
| The folding and faulting found in the rocks of the Blue Ridge Mountains of Virginia were created by — | collisions of continental plates |
| What are the types of evidence Wegener used to support continental drift? | shape of continents fossils mountains or rocks |
| When the sea floor spreads apart, volcanoes and ridges are formed because - | plates pull apart, magma moves to the surface, building ridges |
| The mid - ocean rift is an example of what kind of plate boundary? | Divergent |
