| 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 _____ than the original rock. | different |
| Freezing and thawing are an example of _______ weathering. | mechanical |
| The movement of rock particles by ice, wind, water, or gravity is called ___________. | erosion |
| The rate of chemical weathering is _____ in hot wet climates than 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 rocks farther apart are an agent of _______ weathering. | mechanical. |
| What has a rock probably been chemically weathered by if it contains iron and becomes soft, crumbly, and reddish brown in color? | Oxygen |
| What may the growth of plant roots and animal activity result in? | mechanical |
| 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 which type of climate? | cold climate |
| What kind of weathering causes the mineral composition of rocks to change? | chemical |
| 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 and is still happening. |
| Why does permeable rock weather easily? | The rocks have air spaces |
| 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. | Water freezing in rocks and acting like a wedge to break a rock apart and then thaws and then does it again. |
| Explain how oxygen causes chemical weathering. | Oxygen mixes with water to form oxidation which can form rust. |
| Predict how the city's climate will affect the weathering of the statue. | 1. Hot rainy summers would speed up the weathering process 2. Freezing and thawing with winter temperatures 3. Air pollution would cause acid rain. |
