Rate of Weathering Vocabulary
| Question | Answer |
|---|---|
| Two important factors that affect rate of weathering | Type of rock and climate |
| minerals | The _______________ that make up the rock determine how fast it weathers |
| Low on the Moh's scale | Dissolve easily |
| High on the Moh's scale | Harder to dissolve |
| Permeable | full of tiny connected air spaces that allow water to seep through) |
| Surface Area | As weathering breaks apart a rock, the amount of _________ ___________exposed to future weathering increases |
| Weathering occurs faster in wet climates because... | Rainfall provides water for chemical changes and for freezing and thawing |
| Weathering occurs faster in hot climates because... | Chemical reactions occur faster when its hot |
| Why is elevation a factor in rate of weathering? | Rocks on top of a mountain are exposed to more rain, wind and ice than those at the bottom. |
| Climate where rocks will weather fastest | Hot and wet |
| Climate where rocks will weather slowest | Cold and dry |
