| 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 |
| the movement of rock particles by ice, wind, water, or gravity is called _______________ | mechanical |
| the rate of chemical weathering is _____________ in hot, wet climates than in cold, dry climates. | erosion |
| the gas that causes rock containing iron ti oxidize is ________________. | oxygen |
| the type of weathering that occurs 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? | mechanical |
| 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? | hot and wet |
| What kind of weathering causes the mineral composition of rocks to change? | cold climate |
| What type of climate causes weathering to happen rapidly? | chemical |
| What is ice wedging? | hot and wet climate |
| What is uniformitarianism? | water freezing in rocks and acting like a wedge to break the rock apart. |
| Why does a permeable rock weather easily? | the same process that happened in the past to today |
| What can scientists infer from the rounded shape of the Appalachian Mountains? | air holes |
| A marble statue is left exposed to the weather. What agent of mechanical | they have been weathering for many years |
| Describe how freezing and thawing of water causes mechanical weathering. | freezing and thawing |
| Explain how oxygen causes chemical weathering. | oxygen mixes with the water to form oxadation |
| Predict how the city's climate will affect the weathering statue. Give reasons for your prediction. | some of the reasons why the statue may weather is because of he pollution and the wet climate would cause acid rain, the hot/cold climate my result in freezing and thawing acid ice wedging and the fastest weathering occurs in hot and wet climates. |
