Terms | Definitions |
|---|---|
 rocks | an solid of minerals or mineral - like matter that occurs naturally as part of our planet. |
| igneous | magma cools and hardens beneath the surface or as the result of a volcanic eruption |
| sedimentary | compacted and cemented together developed through a long process that starts with weathering and ends with lithification |
| metamorphic | under extreme pressure and temperature conditions sedimentary rocks will change |
| rock cycle | consists of many process that change earth's cycle |
| magma | molten material that forms deep beneath earth's surface |
| lava | magma that reached the surface |
| weathering | process when rocks are physically and chemically broken down by water, air, and living things |
| sediments | weathered pieces of earth's materials |
| rock cycle is powered by heat from earth's interior. internal source is heat external source is weathering and the movement of weathered materials = produce sedimentary rocks (igneous and metamorphic) | what powers the rock cycle? Internal source and External source |
| intrusive igneous | rocks that form when magma hardens beneath earth's surface |
| extrusive igneous | when lava hardens the rocks are formed |
| erosion | involves weathering and the removal of rocks |
| 4 agents | water the most powerful, wind, ice (glaciers), gravity |
| deposition | process by which an agent of erosion loses energy and drops sediments its carrying |
| compaction | process by which sediments are squeezed together by the weight of overlying materials driving out water |
| cementation | takes place when dissolved minerals are deposited in the tiny spaces among the sediments |
| metamorphism | means to change form |
| hydrothermal solutions | hot, water- based solutions escape from a mass of magma |
| non foliated | a rock that does not have a banded texture |
| foliated | the resulting alignment usually gives the rock a layered or banded appearance |
| cooling | magma to igneous |
| melting | igneous to magma |
| weathering and erosion | igneous to sediments |
| compaction and cementation | sediment to sedimentary |
| heat and pressure | sedimentary to metamorphic |
| weathering and erosion | metamorphic to sediments |
| melting | metamorphic to magma |
| heat and pressure | igneous to metamorphic |
| weathering and erosion | sedimentary to sediments |
| igneous rocks | Which rock follows cooling and crystallizing? |
| compacting and cementing | Which process would follow sediments on the rock cycle? |
| sedimentary rock | When sediments are compacted and cemented what type of rock occurs? |
| metamorphic rock | Assuming a rock doesn't melt in the process of heating and pressure what type of rock will form? |
| rock cycle | Draw the rock cycle. Include all processes and contents. Begin with magma at the top of the cycle. |
| intrusive igneous rock | What is a rock that forms when magma hardens beneath Earth's surface? |
| extrusive igneous rock | What is a rock that forms from cooling lava classified as? |
| coarse grained texture | What type of texture does a rock have when it forms from a large mass of magma that solidifies slowly far below Earth's surface? |
| glassy texture | Lava that cools so quickly that ions do not have time to arrange themselves into crystals will have what type of texture? |
| they decrease in size | As the rate of cooling increases what happens to the size of the crystals? |
| Large crystals and small crystals | The igneous classifications of coarse-grained and fine-grained mean... |
| weathering, erosion, deposition, compaction and cementation | What is the order of the five processes involved in sedimentary rock formations? |
| clastic sedimentary rock | What type of sedimentary rock is formed by weathered particles of rocks and minerals? |
| rock was formed near a beach or stream bed | What does it suggest when there are ripple marks in sedimentary rocks? |
| Clastic and chemical (and also a sub-category biochemical) | The classifications of sedimentary rock are... |
| a few kilometers below Earth's surface | Where do most metamorphic processes take place? |
| Earth's interior | Where is the energy source found that drives the processes that form igneous and metamorphic rocks? |
| The Sun | The rock cycle is driven internally by heat from Earth's interior, and externally by energy from ... |
| heat, pressure and hydrothermal solutions | Name the agents of metamorphism. |
| Foliated = crystals combine and form visible bands Non-foliated = non-banded texture | What are the two classifications of metamorphic rock and describe each. |
| life | The prefix bio- refers to biology which is the study of ...? |
| The peaks of the Himalayas used to be an ocean floor | Why have fossils of marine animals been found buried in the Himalayas? |
| hydrothermal solution | What is a hot, water rich fluid that is associated with a cooling magma body? |
| water, wind, ice (glaciers), gravity | What are the major erosional agents that can pick up, transport, and deposit the products of weathering? |
| Igneous rock forms from melted rock and metamorphic forms from heat and pressure. These processes would destroy anything that may come in contact with it. | Why are fossils only found in sedimentary rock? |
