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 |
