| Question | Answer |
|---|---|
| geologist (geólogo) | A person who studies geology (geo = Earth ology = study ist = a person who) |
| fault | A weak spot in the Earth's crust. Earthquakes are likely to occur here |
| inner core | Innermost layer of the Earth - Solid due to pressure - Hot! |
| outer core | Layer of of the Earth above the inner core |
| mantle | Layer of the Earth below the crust |
| crust | Outermost layer of the Earth |
| tension | Pulling apart force |
| compression | Pushing together force |
| shear | Sliding or twisting force |
| plates | Pieces of the Earth’s crust that are in motion, floating on the mantle |
| magma | Molten rock below the Earth's surface |
| lava | Molten rock above the Earth's surface - emerges through a volcano |
| weathering | The breakdown of rock and soil into smaller pieces |
| erosion | The carrying away of material by wind or water |
| physical weathering | Breakdown of rock by wind, rain, or moving water |
| chemical weathering | Breakdown of rock by a chemical process such as acid rain |
| deposition | Eroded material is deposited or dropped off when the wind or water slows down |
| delta | A large triangular shaped area of land at the mouth of a river caused by the deposition of eroded sand or rock |
| compound | Two or more elements combined - examples include salt sugar |
| metallic | Metal-like - high luster - relativelyhard |
| physical properties | Property of a substance that is easy to observe - examples, color, hardness, density, melting point, etc. |
| crystals (cristales) | The geometric shape formed by different minerals in their natural state |
| luster | How light bounces off a mineral - shininess |
| streak | The color of the material left when a mineral is rubbed against a hard rough surface |
| Moh's hardness scale | A measure of how well a mineral resists scratching 1 is soft 10 is hard |
| ore | A mineral in its raw state, it contains valuable substances that people use - iron is refined from _____ to make iron |
| igneous rock | Formed by fire when cooled above ground, crystals are smaller when cooled below ground, crystals are larger |
| pumice | Rock formed as lava cools |
| sedimentary rock | Rock formed by sediments deposited in a river, lake, or ocean - add millions of years, pressure and maybe chemical "glues" |
| limestone | A sedimentary rock formed at the bottom of the ocean |
| metamorphic rock | Rock that has undergone change in the Earth by heat and pressure - coal is an example |
| granite | An igneous rock |
| rock cycle (ciclo de la roca) | A never ending cycle in which rocks are created, changed, decay, and are reformed |
| landslide | Sudden movement of a section of rock or soil down a hill |
| fossils (fósiles) | Remains or evidence of a plant or animal that once lived - found in limestone or other sedimentary rocks |
| Bonus: What is Shangri La | Bonus question - look up the answer |
| cover crop | Grass or other crop planted to prevent erosin |
| mineral | Substances occurring in nature, of definite chemical composition and usually of definite crystal structure |
