___________ rock form when other types of rocks are subjected to intense heat and pressure. Ex. marble & slate | Metamorphic |
______ metamorphism is a change in the texture, structure or chemical composition of a rock due to change in temperature and pressure over a large area. | Regional |
This sedimentary rock often contains fossils, and forms from the remains of marine (sea) organisms. | Limestone |
Metamorphic rock that is ____ has been exposed to tremendous pressure at tectonic plate boundaries, which causes its minerals to form layers of bands. | Foliated |

The strength of an earthquake is measured by | Richter scale |
The measure of how much damage an earthquake causes is called | Intensity |
The measure of hoe much damage is made by an earthquake is measured by | Modified Mercalli |
Bits of rock and ash that are ejected from a volcano during an explosive eruption are called | Pyroclastic material |
The resistance to flow of a fluid; the thickness of stickiness of magma/lava | Fiscosity |
The Hawaiian islands formed from a hot spot in the ocean floor, unlike Japan which is considered an | Island arc |
