Question | Answer |
Geology | study of Earth’s composition, structure, and history |
Continental Plates | made of crust and lithosphere |
Main Layers of the Earth | Outside in: crust, mantle, core |
Mineral | naturally occurring, inorganic solid with a crystal structure, and characteristic chemical composition |
Rock classification | igneous, metamorphic, or sedimentary |
Metamorphic | formed by intense heat and pressure |
Rock Cycle | a series of processes in which rocks are changed from one type to another |
Sedimentary rock | formed by compaction and cementation |
Mid | ocean ridges |
Subducting plates | more dense, forms trench |
Convection currents | cycle of heating and cooling in the mantle |
Small crystal igneous rocks | cool quickly, fine grained |
Large crystal igneous rocks | cool slowly, coarse grained |
Porphytic | mixture of small and large crystals |
Streak | powder form of the material |
Luster | light reflecting off the material |
Cleavage | angle at which the mineral breaks |
Crystal shape | due to internal atomic structure |
Color | changes due to impurities |
Hardness | ability to scratch another material |
Density | mass to volume ratio |
Reactivity | reaction to an acid |
Divergent | plates move away, mid |
Convergent | plates move towards each other, subduction zones |
Transform boundary | slide past each other, faults |
Rock cycle diagram | identify types of rocks and processes that form them |
Subduction diagram | process occurring at different points, types of boundaries |
Layers of rock diagram | relative age of rocks, |
