| A | B |
|---|
| igneous | What kind of rock forms when molten rock cools & hardens? |
| sedimentary | What kind of rock forms when broken down pieces of rock settle to the bottom of water & get pressed and cemented together? |
| metamorphic | What kind of rock forms when existing rock is changed deep inside earth by extreme heat & pressure? |
| melted | What does molten mean? |
| magma | molten rock beneath the surface |
| lava | molten rock that pours onto the surface |
| quickly | How does lava cool? |
| slowly | How does magma cool? |
| large | What size crystals form when magma cools slowly? |
| small | What size crystals form when lava cools quickly? |
| glassy | What word describes the texture of a rock that formed when lava cools immediately with no visible grains? |
| intrusive & extrusive | 2 types of igneous rocks |
| extrusive | igneous rocks that form from lava |
| intrusive | igneous rocks that form from magma |
| clastic, chemical, & organic | 3 types of sedimentary rock |
| organic | kind of sedimentary rocks that form where remains of organisms are deposited in thick layers |
| clastic | kind of sedimentary rocks formed from broken pieces of rock fragments that are squeezed together |
| sediments | small, broken down solid particles of material from rocks or organisms which have been moved by water, wind, or ice |
| weathering | process that breaks rock down into smaller pieces |
| erosion | process that moves fragments of rock by water, wind, or ice |
| deposition | process in which sediment settles down in water |
| rock cycle | a series of processes on Earth's surface & interior that slowly changes one kind of rock into another |
| by how they form | How are rocks grouped or classified? |
| "changed form" | what the word metamorphic means |
| "formed by fire" | what the word igneous means |
| "to settle" | what the word sedimentary means |
| foliated & nonfoliated | 2 types of metamorphic rock |
| layers in metamorphic rock | What does foliated mean? |
| the continuous changing of rock from one type to another | What does the rock cycle explain? |
| sedimentary | What type of rocks involve cementation & compaction in their formation? |
| igneous | What type of rocks involve melting, cooling, & solidifying in their formation? |
| sedimentary | What type of rocks involve weathering, erosion, & deposition in their formation? |
| marble, gneiss, & slate | 3 examples of metamorphic rocks |
| granite, basalt, & obsidian | 3 examples of igneous rocks |
| sandstone, limestone, & coal | 3 examples of sedimentary rocks |
| changing | What are rocks always doing? |
| minerals & other materials | What are rocks made of? |
| deep underground | Where do metamorphic rocks form? |
| igneous | What kind of rock forms from the cooling of magma below the surface or lava at the surface? |
| because we use them for so many things | Why are rocks an important resource to society? |
| sedimentary | Which type of rock forms in layers? |
| the heat of the mantle deep underground | Where does the heat come from that changes a rock into a metamorphic rock? |
| compaction | the process that presses together layers of sediment |
| true | True or false? Any type of rock can change into any other type of rock. |
| sedimentary | What kind of rock forms from material that settles on the ocean floor? |
| cementation | the process that glues particles into sedimentary rock |
