Common Assessment Q1
Rock Cycle, Plate Tectonics
| Question | Answer |
|---|---|
| Deposition | The process of sediments setting in a new location |
| Erosion | The movement of rock particle by water wind, ice or gravity |
| Extrusive Igneous Rock | Igneous rock that forms from lava on Earth’s surface |
| Igneous Rock | Rocks that are formed from cooled and solidified magma or lava |
| Intrusive Igneous Rock | Igneous rock that forms beneath the Earth’s surface |
| Lava | Molten rock that reaches the Earth’s Surface |
| Magma | Molten rock beneath Earth’s surface |
| Metamorphic Rock | Rocks that are formed from existing rock that undergoes heat and pressure changes |
| Pressure | One of the forces that cause metamorphic rocks to form |
| Rock Cycle | The continuous process rocks undergo to from, breakdown, and transform into different rock types over time |
| Sediments | Small particles of rocks, minerals, and organic material |
| Sedimentary Rock | Rocks that are formed from compacted and cemented sediments |
| Subduction | The process where one tectonic plate moves under another, bringing rock deep into the Earth |
| Uplift | The movement of rocks layers upward due to tectonic forces |
| Weathering | The breakdown of rocks into smaller pieces by wind, water, or biological activity |
| Compaction | the process of sediments being pressed together |
| convergent boundary | A plate boundary where two plates move toward each other. |
| convection currents in the mantle | circular currents where heated material rises and cooler material sinks back toward the core; this is what is responsible for moving the earth's plates; like a conveyor belt |
| hot spot | An area where magma from deep within the mantle melts through the crust above it creating volcanoes |
| Lithosphere | the rigid outer part of the earth, consisting of the crust and upper mantle |
| Asthenosphere | The soft layer of the mantle on which the lithosphere floats |
| oceanic plate | Thin plates that form the ocean floor; more dense than continental plates |
| continental plate | tectonic plate that lies under a continent, older and less dense |
| cementation | The process in which minerals precipitate into pore spaces between sediment grains and bind sediments together to form rock. |
| melting and cooling | the processes that form igneous rock |
| volcanic island arc | a series of volcanoes formed at a subduction zone |
| oceanic-oceanic subduction | A boundary along which a plate carrying oceanic crust sinks beneath another plate with oceanic crust. |
| oceanic-continental subduction | A boundary along which a plate carrying oceanic crust sinks beneath a plate with continental crust. |
| continental-continental convergent boundary | when two continental plates collide, mountain ranges are created as the colliding crust is compressed and pushed upward (ex: the Himalayas) |
| ring of fire | the chain of volcanoes that lines the Pacific Rim |
