| 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 know 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 ______. | Rock and Climate |
| Acid rain causes very rapid ______ weathering | Chemical |
| The most important agent of weathering is ______. | Water |
| After chemical weathering, the chemical makeup of the rock is ______ than the original rock | different |
| Freezing and thawing are an example ______ 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 what type of climate? | Cool |
| 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 |
| What is ice wedging? | Water freezes in rocks and acts like a wedge to break apart the rocks |
| What is uniformitarianism? | Something that happened in the past is still happening. |
| Why does permeable rock weather easily? | It has tiny air spaces that allow water to seep into it |
| What can scientists infer from the rounded shape of the Appalachian Mountains? | That they are older |
| 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 freezes in rocks and acts like a wedge to break apart the rocks |
| Explain how oxygen causes chemical weathering. | Iron combines with oxygen and water to form chemical weathering (oxidation) |
| Predict how a 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 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. |
