| Igneous rock form from molten rock in the form of ____ or ____. | lava or magma |
| Lava cools ____. | quickly |
| Magma cools ____. | slowly |
| When volcanic material erupts and cools and crystallizes on Earths surface, it forms a type of igneous rock called ___ ___. | extrusive rock |
| Some extrusive cools so quickly that ____ doesn't have time to form. | crystals |
| ___ ___ is rock thats forms when lava cools too quickly to grow crystals. | intrusive rock |
| Intrusive rocks contain large ___ because the magma cools slowly. | crystals |
| The two characteristics that can help to identify igneous rocks are ___ and ___. | texture and composition |
| If the crystals are small or impossible to see without a magnifying tool then the rock is ___. | intrusive |
| Igneous rocks are classified, in part, due to their ___. | silica content |
| ____ minerals contain more silica. | light |
| ___ rate determines the type of igneous rock that forms. | cooling rate |
| ___ and ___ can change the physical or chemical properties of a rock. | water and air |
| This change can cause rock to break apart, dissolve, or to form new ___. | minerals |
| When water travels through rock some of the rock can get dissolved and ___ to new locations. | transported |
| The sediments eventually are ___, or laid down, where they can then accumulate in layers. | deposited |
| The weight from layers of deposited sediment forces out fluids and decreases space between grains during a process called ___. | compaction |
| Compaction leads to ___, in which minerals dissolved in water crystallize. | cementation |
| Sedimentary rocks are classified by how they ___. | form |
| ____ form from broken pieces and fragments called ___ | clastic/ clast |
