| Metamorphic rock formed from limestone under pressure and high heat | marble |
| A rock which sometimes holds large oil reservoirs | shale |
| The type of rock formed by the combination of heat and pressure or chemical action | metamorphic |
| A layered rock which forms from sand settling and becoming cemented together by other chemicals | sandstone |
| A rock made up of all four minerals, which may decompose quickly into gravel and eventually sand | granite |
| Rock formed by sudden cooling of magma filled with tiny gas bubbles | pumice |
| A kind of glass formed from sudden cooling of molten rock | obsidian |
| A naturally-occurring heat reflector mineral | mica (or schist) |
| The most common mineral in the Earth's crust | quartz, silica quartz |
| Minerals, as opposed to rocks, are made up of this number of chemicals. | one |
| All of the energy that drives Earth's rock cycle comes from the interior of these two objects. | the Earth and the Sun |
| This type of rock occurs/happens in the part of the rock cycle which follows sedimentation of the material called sediment which results from weathering and erosion. | sedimentary |
| This type of rock occurs/happens in the part of the rock cycle which follows cooling of magma (molten/melted rock). | igneous |
| If granite undergoes high temperatures and high pressures at depth within Earth (but without melting), this type of rock will be formed. | metamorphic |
| The three groups of rock are classified by this characteristic or process | how they are formed |
| This condition of the continental lithosphere prevents it from being forced down into the mantle, so that subduction zones are not commonly found at convergent continental-continental boundaries. | *buoyant *buoyancy *too buoyant *high buoyancy *greater buoyancy *low density *less dense *lower density *buoyancy force |
| This results when divergence occurs between two oceanic plates. | *seafloor spreading |
| This kind of plate boundary occurs where two plates grind laterally past each other parallel to the boundary without destroying or producing lithosphere. | transform fault |
| This forms when one oceanic plate is forced beneath another plate. | *subduction zone |
| In plate tectonic theory, the lithosphere is divided into this quantity of minor plates (aside from any major ones). | *many *lots *several *dozens *bunches *a lot |
| In plate tectonic theory, the lithosphere is divided into this number of major plates (aside from any minor plates). | seven |
| Three proposed mechanisms of plate motion | 1. ridge-push 2. mantle convection 3. slab-pull |
| A divergent boundary at two oceanic plates can result in this. | *rift valley |
| In the plate tectonic theory, a plate can be made up of this (or these) kind(s) of lithosphere. | *continental and oceanic |
| This type of landform develops at plate boundaries where one oceanic plate descends beneath another. | *volcanic island arc |
| This type of boundary occurs where two plates move toward each other, causing one plate to descend into the mantle beneath the other plate. | convergent |
| The Hawaiian Islands were formed when the Pacific Plate moved over one of these. | *hot spot |
| According to the theory of plate tectonics, this is divided into plates. | lithosphere |
| The main source of downward convection flow in the mantle | *slab-pull |
| The thermal convection that drives plate motion is caused by an unequal distribution of this factor. | heat |
| Deep ocean trenches are associated with these zones. | subduction |
| The change of the viscosity ("stickyness," or slowness of flow) of lava as its temperature goes up | *decreases *goes down *gets less *lessens |
| The broad, slightly done-shaped type of volcanoes of Hawaii | shield |
| Volcanic island arcs are associated with this type of convergent plate boundary. | *oceanic-oceanic |
| Continental volcanic arcs are associated with this type of convergent plate boundary. | *oceanic-continental |
| The Hawaiian Islands are associated with this type of volcanism. | intra-plate, or intraplate (not INTER-plate, or INTERplate) |
| The two factors in the magma, along with dissolved gases in the magma, which help determine whether a volcanic eruption will be violent or relatively quiet. | 1. temperature 2. composition |
| Highly explosive volcanoes tend to have this level of gas content in their magma. | *high *higher |
| Highly explosive volcanoes tend to have this level of viscosity, or "sticky-ness," in their magma. | *high *higher |
| Highly explosive volcanoes tend to have this level of silica in their magma. | *high, or higher |
| The most violent volcanic eruptions are associated with this type of volcano. | composite cones , or stratovolcanoes |
| When an earthquake occurs, energy radiates in all direction from this location, or source | focus |
| The minimum number of seismic stations needed to determine the location of an earthquake's epicenter | three |
| The multiple of increase in wave amplitude seen from an earthquake measuring 5.4 on the Richter scale compared to one measuring 4.4 | *10 times (ten times greater) |
| This type of graph can be used to find the distance to the epicenter of an earthquake. | *travel-time |
| The measure of the size of the amplitude of the seismic waves it produces | magnitude |
| This device or reading shows that P-waves travel faster than S-waves. | *seismograph (device), or seismogram (reading) |
| The place on the surface directly above the focus of an earthquake | epicenter |
| The Richter magnitude of an earthquake is determined from this measurement of the largest of these waves. | seismic |
| Major earthquakes are sometimes preceded by these smaller earthquakes. | foreshocks |
| The amount of shaking produced by an earthquake at a given location | intensity |
