ESC1 Exam 1
Earth Science 1
| Question | Answer |
|---|---|
| Halite | NaCl |
| Calcite | CaCO3 |
| Pyrite | FeS2 |
| Quartz | SiO2 |
| Diamond | C |
| Graphite | C |
| 3 types of basaltic volcanoes | Shield, flood basalt, cinder cones |
| Journey of sediments | Weathering (physical/chemical), erosion, transport, deposition, compaction, and cementation |
| Types of mass wasting | Rock falls, rock avalanches, rock slides, slump, earth flow, soil creep |
| Mineral classifications | Color, hardness, streak, luster, transparency, reactions to magnets and acid,crystal formation, |
| What kind of volcano is Mt. Rainer | Stratovolcano |
| What kind of volcano is St. Helens? | Stratvolcano |
| Mohs scale | Determines hardness; Diamond, conundrum, topaz, quartz, pyrite, O, Fluorite, Gypsum, Talc |
| CA mineral, gem, and rock | Gold, benotite, serpentine |
| Causes of metamorphism | Stress, heat, and fluids |
| 3 types of sedimentary rocks | Clastic, chemical and bioclastic |
| What are clastic rocks? | Rocks made up of different pieces |
| What are chemical rocks? | Rocks that are formed from chemicals that are left over from transportation. I.e. rock salt made from evaporites |
| What are bioclastic rocks? | Rocks that have dead plants |
| What is chemical weathering? | Dissolution of minerals in rock from water |
| Define angle of repose | The angle which is above gravitational stability |
| Define hydrolysis | Adding water and changing the crystal structure |
| Define erosion | Removal of rocks and sediment due to wind water or gravity |
| Define deposition | Decrease in speed |
| Define delta | Where the stream meets the ocean and minerals begin to deposit. Creates fan of particles. Bigger rocks settle first |
| Alluvial fans | Rivers/streams coming down from the side o a mountain. More angular grains due to less transport |
