Packet answer key: Page 1: Oxygen, topography, ice wedging, soil, tannic, mechanical, carbonic, rust, chemical, weathering Page 2: 1. Weathering is a mechanical or chemical surface process that breaks rocks into smaller pieces. 2. The principal difference is that in chemical weathering, the chemical composition of the rock will change and in mechanical weathering, the rocks are just broken in smaller pieces, there is no change in the chemical composition. 3. Living organisms 4. Hot and wet 5. Chemical 6. Oxygen 7. Soil 8. Topography 9. Greater than 10. Mechanical 11. Carbon Dioxide 12. Rapidly 13. Hummus 14. Tannic acid Page 3: 1 – inner core, 2 – mantle, 3 – crust, 4 – lithosphere, 5 – plates Page 4: 1 – faults, 2- plates, 3 – lithosphere, 4 – asthenosphere, 5 – convection, 6 – crust, 7 – lithosphere, 8 – asthenosphere, 9 – outer core, 10 – inner core Page 5: Note taking worksheet – Section 1: Earth’s moving plates is for 6/13 only.
