Rocks and Rock Cycle
Review questions on rocks, the three kinds of rocks, and the rock cycle.
| Question | Answer |
|---|---|
| What process(es) change sedimentary rock to metamorphic rock? | Weathering and erosion |
| How do igneous rocks form? | When magma or lava cools and crystalizes |
| How do sedimentary rock form? | Sediments are deposited then compacted then finally cementation occurs. |
| How can an igneous rock become metamorphic rock? | Heat, pressure, or chemical fluids |
| How can sedimentary rock become igneous? | rock must have heat and pressure and changes into another type of rock. Then melts, becomes magma then cools and crystallizes. |
| What qualities does a rock have to possess? | a natural, solid mixture of mineral and grains |
| A rock has smaller crystals when what happens? | magma cools fast |
| What is uplift? | A tectonic process that forces rocks up from beneath Earth's surface |
| Which of the following does not happen on Earth's surface? | Melting because the temperature isn't hot enough |
| Which of these does NOT occur during the rock cycle? | faulting |
| What is the difference of magma and lava? | One is out of ground while other is not |
| What are similarities of magma and lava? | made of hot, liquid rock |
| When would the land become scare with vegetation and the rock cycle wouldn't be the same? | If weathering did not exist on Earth |
| We know igneous was the first rock on Earth because_______________________________. | it was the originally made of molten rock. |
| What is deposition? | laying down of sediment--layering |
| Compaction is_________________________. | the squeezing together of sediment |
| The gluing together of sediment is__________. | cementation |
| When rains seeps through the earth it glues the sediment together. What is the "glue"? | minerals |
| The process of cementation, deposition, and compaction is forming what? | sedimentary rock? |
| If magma cools slowly the __________ will be bigger. | crystals |
| What is the process that: provides materials to make other rocks, forms other rocks, and changes by forces at Earth's surface? | Rock Cycle |
| Metamorphic rock is formed through what? | Heat and pressure |
| How does an igneous rock change to sedimentary? | Weathering and erosion, deposition, compaction, and cementation |
| Rock particles are made of: | Mineral crystals, mineral fragments, and rock fragments |
| What defines texture? | grain size & compostion |
| What is in the rock is called what? | composition |
| What are rocks classified according to? | texture and compostion |
| Grains are identified according to what? | shape, chemical composition, and size |
| Remains of organisms and volcanic glass can be in what? | Rocks |
| When lava or minerals cool and crystallize what forms? | igneous rock |
| Wind, running water, gravity, and ice are the four forces that do what? | break Earth down |
| What is sediment made of? | broken down rock material |
| How is sediment formed? | When it is are broken down in smaller pieces or dissolved |
| What changes when a sedimentary or igneous rock into metamorphic rock? | texture and compostion |
| How does another type of rock change into a metamorphic rock? | Heat, pressure, and chemical fluids |
| What is a series of processes that change one type of rock into another? | rock cycle |
| Sediments are _____________ to make sedimentary rock. | deposited, compacted, and cemented |
| Magma has to what in order to make igneous rock? | cool and crystalize |
| How does metamorphic rock change to magma? | by melting down |
| How do all the rocks get to the surface? | through the process of uplift |
| Extreme temperature and pressure make what kind of rock? | Metamorhic |
| What are the three types of rocks? | sedimentary, igneous, and metamorphic |
