| Rapid chemical weathering can be cause by ____________, which is rain combined with pollutants. | Acid Rain. |
| Some plants produce acids that result in ___________ weathering. | Chemical. |
| The factors that determine the rate of weathering are the type of _______ and ________. | Rock and climate. |
| Acid Rain causes very rapid _______________________ weathering. | Chemical. |
| The most important agent of chemical weathering is_________. | Water. |
| After chemical weathering, the chemical makeup of the weathered rock is _____________ then the original rock. | Diffrent. |
| Freezing and thawing are an a example of _________________ weathering | Mechanical. |
| The movement of rock particles by wind, Ice, Water, or gravity is called ___________ | Erosion. |
| The rate of chemical weathering is _____________ in hot , wet climates then in cold, dry climates. | Faster |
| The gas that causes rock containing iron to oxidize is ____________. | Oxygen |
| The type of weathering that occurs due to release of pressure is ________________ weathering | Mechanical |
| Plant roots that force cracks in to rocks farther apart are an agent of_______________ weathering. | Mechanical |
| What has a rock probably been chemically weathered by if it contains iron becomes soft, crumbly, and reddish-brown in color? | Oxygen |
| What may the growth of plant roots and animal activity result in? | Mechanical weathering |
| What is the agent of mechanical weathering called in which rock is worn away by the grinding action of other rock particles? | Abrasion |
| Granite will last a long time when it is used for building in what type of climate? | Cold Cilmates |
| what kind of weathering causes the mineral composition of rocks to change? | Chemical weathering |
| what type of climate causes weathering to happen rapidly? | hot and wet climate. |
| What is Ice wedging? | Water freezing in rocks and acting like a wedge to break the rock apart. |
| What is uniformitarianism? | The same process that happened in the past as today. |
| Why does a permeable rock weather easily? | Air holes |
| What can scientists infer from the rounded shape of the Appalachian mountains? | They have been weathering for many years |
| A marble statue is left exposed to the weather. What agent of mechanical weathering probably will cause it to weather. | Freezing and thawing. |
| Describe how freezing and thawing of water causes mechanical weathering. | When water freezes it expands. |
| Explain, how oxygen causes chemical weathering. | oxygen mixes with water to from oxidation. |
| Predict how the city's climate will effect the weathering of the statue. give reasons for your prediction. | Some of the reasons why the statue may weather is because of the pollution and the wet climate would cause acid rain, the hot / cold climate may result in freezing and thawing and ice wedging and the fastest weathering occer in hot and wet climate. |
