| 4 spheres | Atmosphere, Hydrosphere, Geosphere, Biosphere |
| 3 main parts of the geosphere | crust, mantle, core |
| Definition of a rock | a solid mixture of organic material and minerals |
| 3 types of rocks | sedimentary, igneous, metamorphic |
| Formation of igneous rock | cooled & hardened lava or magma |
| Formation of sedimentary rock | weathering, erosion, deposition, compaction, and cementation of sediment |
| Formation of metamorphic rock | heat and pressure deep within the earth |
| Definition of mechanical weathering | physical forces break rock into smaller pieces without changing the rock's chemical composition |
| Frost Wedging | Weathering process that involves the constant freezing and thawing of water |
| Definition of chemical weathering | process that changes rock into one or more new compounds |
| Velocity of stream | controls its ability to erode and transport material |
| Dissolved load | particles dissolved in solution carried in stream |
| Suspended load | particles suspended in stream |
| Bed load | particles laying on stream bottom |
| Delta | depositional feature formed where stream enters a lake or ocean |
| 3 Factors that affect the rate of weathering of rocks | climate, amount of exposed area, rock characteristics |
