Unit 4 Rocks SG (ES)
Answer | Question |
---|---|
Igneous | Form when magma or lava cools and crystallizes. |
Sedimentary | Form where sediment is deposited. |
Metamorphic | When rocks are exposed to extreme temperatures and pressure or the addition of chemical fluids, ___________ rocks result. |
Intrusive | The type of igneous rock that forms when magma cools under ground. |
Erosion | Movement or transportation of pieces of rocks. |
Weathering | Breaking up of rocks into smaller pieces. |
Compaction | Compression of rocks together. |
Cementation | Dissolved minerals crystallize and cement rocks together. |
Rock Cycle | Describes how Earth's materials and processes form and continuously change rocks. |
Lava | Molten rock that has erupted onto Earth's surface. |
Magma | Molten rock below the Earth's Surface. |
Foliated | The type of metamorphic rock that has parallel layers of flat and elongated minerals. They are a result from an uneven distribution of pressure during metamorphism. |
Non-Foliated | The type of metamorphic rock that has mineral grains with a random interlocking texture/ no obvious alignment of the mineral crystals. |
Rock | A mixture of minerals or grains. NOT crystals. Some form near the surface and others are deep in the crust. |
Clasts | The broken pieces and fragments in sedimentary rocks. |
Chemical Rock | The type of sedimentary rock that forms when minerals crystallize directly from water. |
Biochemical Rock | |
Organic Rock | The type of sedimentary rock that is formed by organisms or contain the remains of organisms. |
Clastic Rock | The type of sedimentary rock that is made up of broken pieces of rock fragments and minerals. |

Contact Metamorphism | When magma comes in contact with existing rock, it's thermal energy and gases interact with the surrounding rock. |
Regional Metamorphism | Formation of metamorphic rock bodies that are hundreds of square kilometers in size. This process can create an entire mountain range of metamorphic rocks. |
Uplift | A structurally high area in the crust, produced by movements that raise the rocks, as in a broad dome or arch. |
Parent Rock | The rock that changes during metamorphism. |
Kilo Bars | |
Understand that slow cooling process form large crystals, and fast cooling processes form small crystals. | |
Explain how each type of rock (Igneous, Sedimentary, Metamorphic) forms. | |
Identify where each type of rock can be found. | |
Be able to give several examples for each type of rock. | |
Use a table to answer questions about rocks. | |
Extrusive | The type of igneous rock that forms when volcanic material erupts, cools, and crystallizes on Earth's surface. |
