| What mineral fizzes when it comes into contact with hydrochloric acid | calcite |
| What would you use the morgans scale of hardness for | to identify minerals |
| What is the second most abundant element in earth’s crust | silicon |
| What is the composition of magma | the molten or semi |
| What are the four factors that affect how rocks melt and crystallize | temperature, pressure,water content, and mineral composition |
| Different combinations of what result in different types of what | temperature, pressure, metamorphism |
| During ? the minerals in ?change into ? that are stable under the new ? conditions | metamorphism, a rock, new minerals, temperature, pressure |
| Most ? reflect the original chemical composition of the parent rock | metamorphic rocks |
| Chemical changes are especially common during contact ? near igneous intrusions | metamorphism |
| Hydrothermal fluids invade the surrounding rocks and change their ? | mineralogy, texture, chemistry |

| Which of the following is a common mineral found in both organic and chemical sedimentary rocks | calcite |
| By what process re surface materials removed and transported from one location to another | deposition |
| What mineral commonly forms porphyroblasts | euhedral |
| What are two primary causes of lithification | compaction and cementation |
| Why is the term clastic appropriate for particles whether form solid rock | broken pieces from solid rock |
| Describe the two main types of cementation | growth of new minerals and enlargement of existing minerals |
| How are the three types of sedimentary rocks classified | they classify on how they form |
