| Question | Answer |
|---|---|
| A rock that contains tiny, connected spaces through which in water can move is said to be_____________. | Permeable |
| 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 ____________. | Rock & 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 weathering 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 the rock 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 activities results 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? | Mechanical |
| What kind of weathering causes the mineral composition of rocks to change? | Chemical |
| What type of climate causes weathering to happen rapidly? | Hot,Wet |
| What is ice wedging? | Water freezing in rocks and acting like a wedge to break apart. |
| What is uniformitarianism? | The same process that happened in the past is happening today. |
| Why does a permeable rock weathering easily? | It has a tiny air spaces that allows water to seep into the rock. |
| What can scientist 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 in a crack in a rock in a rock, it expands and makes the crack bigger. Then it thaws and freezes again. |
| Explain how oxygen causes chemical weathering. | Iron combines with oxygen and water to form chemical weathering (oxidation) |
| Predict how the city's climate will affect the weathering of the statue. Give reasons for your prediction. | The pollution and the wet climate would cause acid rain, Thee hot/cold climate may result in freezing and thawing and ice wedging, Faster weathering occurs in hot and wet climates. |
