Earth Science Test 1
| Term | Definition |
|---|---|
| geology | study of solid earth |
| meteorology | atmosphere, weather, climate |
| oceanography | ocean process |
| astronomy | planets, stars, solar system, universe |
| the BLUE on the earth | water, hydrosphere, ice |
| the WHITE on the earth | water condensed into clouds, atmosphere |
| the GREEN on the earth | plants, life, biosphere, living layer |
| the YELLOW/BROWN on the earth | geosphere, solid earth |
| Fresh water is stored as... | ICE |
| Atmosphere is thin or thick? | Thin |
| mantle is how much of the earth? | 80% |
| Mantle is made up of? | Lower Mantle, Asthenosphere, Uppermost Mantle |
| Asthenosphere is made up of? | Ductile material |
| Lithosphere is made up of? | Brittle, rigid layer, breaks under pressure |
| Plate tectonics is caused by which layers? | Lithosphere, Uppermost mantle, and Asthenosphere |
| Continental Crust vs Ocean Crust Density? | Continental is LESS Ocean is MORE |
| Which layer contains magma? | Upper Asthenosphere |
| Evidence for Plate tectonics: | Jig saw fit, fossils shared common areas, mountain ranges, climate (glaciers, coal, closer to south pole) |
| People didn't believe because: | they thought gravity from sun/moon was responsible for all this, and they thought the continents were not part of the same layer |
| Main reason why the inside of the earth changes: | density |
| How the theory arose: |
