| One agent of chemical weathering is __________, which combines with water to form carbonic acid. | Carbon Dioxide |
| The actions of animals most commonly can cause the type of weathering known as __________. | Mechanical |
| Rapid chemical weathering can be caused 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 _________. | Rocks 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 _______ than the original rock. | Different |
| Freezing and thawing are an example of ___________ weathering. | Mechanical |
| The movement of rock particles by 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 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 Climate |
| 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 |
| 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 is happening today |
| Why does a permeable rock weather easily? | It has tiny air spaces that allows water to seep into the rock |
| 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 the rock apart |
| Explain how oxygen causes chemical weathering. | Oxygen mixes with water to form oxidation |
| Predict how the city's climate will affect 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 occurs in hot and wet climates. |
