| Question | Answer |
| What are the 3 types of rocks? | Igneous, Sedimentary, and Metamorphic |
| Define Intrusive | Rocks that are underground/inside earth (slow cooling and big grains) |
| Define Extrusive | Cooled on earth's surface (fast cooling, holes, and small grains) |
| What are the characteristics of Sedimentary rocks? | Biochemical, clastic, and chemical |
| Define Granitic | Light colored |
| Define Basaltic | Dark colored |
| Define Chemical | Made out of solution (evaporated liquid) |
| What characteristics do Igneous rocks have? | Intrusive, granitic, extrusive, basaltic |
| Define Biochemical | A rock that has once living things in it |
| Define Clastic | A rock that's made of other rocks |
| What are characteristics of Metamorphic rocks? | Foliated and Non-foliated |
| Define Foliated | Layers of fragments and minerals in a rock |
| Define Non-foliated | No layers |
| What are compacting and cementing? | Compacting- Squeezing sediments together Cementing- Liquid is between sediments and crystallizes |
| How do you change a sedimentary rock into a metamorphic rock? | Heat and pressure |
| How do you change a metamorphic rock into a igneous rock and what does it turn into? | By using heat and it turns into magma/lava |
| How do you change a igneous rock into sediments and what type of rock is that? | Weather and erode and it turns into sedimentary rocks |
| How do you change a sedimentary (sediments) rock into a igneous rock (magma/lava)? | Melting |
| Can a rock change back into itself? | Yes |
| How do you turn a Igneous rock (magma/lava) into a metamorphic rock? | Heat and pressure |
| How do you turn a metamorphic rock into a sedimentary rock (sediments) | Weathering and eroding |
| Is there a start or end to the rock cycle? | No |
| What igneous rock cools slowly? | Granite |
| What is the term for a rock fragment present in a sedimentary rock? | Clast |
| Light colored minerals, like quartz, contain greater amounts of _______ | Silica |
| Why don't crystals form in volcanic glass? | The lava cools too quickly |
| What rock contains the hard remains of marine organism made from minerals in seawater? | Limestone |
