| Question | Answer |
|---|---|
| Define Rock. | Mixture of one or more minerals, rock fragments, volcanic glass, organic matter, or other natural materials; can be Igneous, Metamorphic, or Sedimentary. |
| Define Sediment. | Loose materials, such as rock fragments, mineral grains, and the remains of once living plants and animals, that have been moved by wind, water, ice or gravity. |
| Define Vesicular. | get back to later! |
| Define Granular. | get back to later! |
| Define Foliation. (foliated) | describes metamorphic rock such as slate and gneiss, whose mineral grains line up in parallel layers. |
| Define Metamorphism. (metamorphic rock) | forms when heat, pressure, or fluids act on igneous, sedimentary, or other metamorphic rock to change its form or composition, or both. |
| Draw and label the rock cycle. | Magma->cools and crystallizes <-Igneous Igneous-> Weathering and Erosion<-Sediments Sediments-> Compact and Cement-> Sedimentary Sedimentary-> Heat, Pressure and Chemical Reactions-> Metamorphic Metamorphic-> melt<-Magma Sedimentary-> melt<-Magma S |
| What processes make a sedimentary Rock? | Cools + Crystallizes, Weathering + Erosion, and Compacting + Cementing. |
| How are Sedimentary Rocks classified? | They are classified by their composition and by the manner in which they formed. |
| What are the classifications of Sedimentary rocks? | Chemical, Detrital, or Organic. |
| What processes make an Igneous rock? | Cooling and Crystallizing. |
| What are the classifications of Igneous rock? | Intrusive or Extrusive. |
| How are Igneous rocks classified? | Basaltic, Granitic, and Andesitic. |
| What processes make a Metamorphic rock? | Heat, Pressure, and Chemical Reactions. |
| How are Metamorphic rocks classified? | It is classified by its composition and texture. |
| What are the classifications of metamorphic rock? | Foliated or non-foliated. |
| Identify the processes forming Igneous rocks. | It goes from magma to Igneous while cooling and crystallizing. |
| Explain the differences between Lava and Magma. | Lava is molten rock that flows from Volcanoes onto Earths surface and Magma is hot melted rock beneath Earths surface. |
| Explain the differences between intrusive and extrusive processes. | |
| Identify the characteristics of the three types of volcanoes. |
