A boundary where plates move together

A boundary where plates move next to each other

A constructive boundary is a

A destructive boundary is a

A conservative boundary is a

Divergeant boundaries are _____ _______ and occur at places like mid-ocean ridges

continent-ocean, ocean-ocean, and continent-continent are different types of

At a convergent boundary, ________ can occur

At a __________-_______ sub-zone, the ______ plate is subducting other the other. This can create mountain ranges like the Andes

Ocean-ocean boundaries create ___ ____ like Japan

At continent-continent boundaries, why are mountains created?

Volcanos and earthquakes are potential hazards at which kinds of convergant boundaries?

The San Andreas Fault is an example of a

Discrete pieces of lithosphere at the Earth's surface that move w/ respect of one another

Sea floor spreading and continental drift are inc'd under

This force is what drives plate movement beginning at the mantle

The two traits of this mantlepiece (badumtsss) are: hot and plastic, which allow plates to move

This was the thing most critical in proving seafloor spreading

A process of recycling oceanic crust

Where would you expect to find new oceanic crust being created?

Rocks become ______ and deform _______ under high pressure and heat

A belt of earthquakes found w/in a downgoing plate at a subduction zone

When a hanging wall slides up relative to a footwall

The highest velocity wave is the

___ stations are needed to find a precise epicenter

To find the location of an epicenter, one must measure the difference between

Compressional stress is associated with which kind of zone?

Most (if not all) transform boundaries are found

An uplifted block is known as

A dropped block is called a... (wait for it...) (...hope its worth the weight...)

A section of a fault that has not experienced an earthquake in a long time

Thinning, divergent plate boundary stress

Thickening, convergent plate boundary stress pushes rocks together

Transform boundary stress that distorts rocks

Divergent volcanism is SiO2 (rich/poor?) and (hot/cold?)

Temperature and SiO2 continent affect a magma's

Influences the type of eruption a volcano can have

Explosive eruptions are more likely to occur at

relatively small, andesitic magma, highly explosive
