Questions for test
| Question | Answer |
|---|---|
| 1.) Some plants produce acids which result in ________________ weathering. | Chemical |
| 2.) A rock that contains tiny, connected spaces through which water can move is said to be ____________________. | permeable |
| 3.) One agent of chemical weathering is ___________________, which combines with water to form carbonic acid. | Carbon dioxide |
| 4.) The actions of animals most commonly can cause the type of weathering known as ________________________. | mechanical weathering |
| 5.) Rapid chemical weathering can be cause by _______________, which is rain combined with pollutants. | Acid rain |
| 6.) Some plants produce acids that result in ____________ weathering. | Chemical |
| 7.) The factors that determine the rate of weathering are the type of ______ and _________. | Rock and climate |
| 8.) Acid rain causes very rapid ______________ weathering. | Chemical |
| 9.) The most important agent of chemical weathering is __________. | Water |
| 10.) After chemical weathering, the chemical makeup of the weathered rock is ______________ than the original rock. | Different |
| 11.) Freezing and thawing are an example of ______________ weathering. | mechanical |
| 12.) the movement of rock particles by ice, wind, water, or gravity is called __________ | erosion |
| 13.) the rate of chemical weathering is ___________ in hot, wet climates than in cold, dry climates. | faster |
| 14.) the gas that causes rock containing iron to oxidize is __________. | Oxygen |
| 15.) the type of weathering that occurs due to release of pressure is ______________ weathering. | mechanical |
| 16.) plant roots that force cracks in rocks farther apart are an agent of ________________ weathering. | Mechanical |
| 17.) What has a rock probably been chemically weathered by if it contains iron and becomes soft, crumbly, and reddish-brown in color? | oxygen |
| 18.) what may the growth of a plant roots and animal activity result in? | mechanical weathering |
| 19.) what is the agent of mechanical weathering called in which rock is worn away by the grinding. | Abrasion |
| 20.) Granite will last a long time when it is used for building in what type of climate | cold or cool |
| 21.) what kind of weathering causes the mineral composition of rocks to change | chemical |
| 22.) what type of climate causes weathering to happen rapidly | hot ,wet |
| 23.) what is ice wedging | water freezes in rocks and acts like a wedge to break the rock apart |
| 24.) what is uniformitarianism | something that happened years ago is happening now |
| 25.) why does a permeable rock weather easily | tiny air spaces which lets liquids seep through to the rock |
| 26.) what can scientists infer from the rounded shape of the Appalachian Mountains | that the mountains are older |
| 27.) a marble statue is left exposed to the weather. what agent of the mechanical weathering probably will cause it to weather | freezing anf thawing |
| 28.) Describe how freezing and thawing water causes mechanical weathering | water freezes in rocks and acts like a wedge to break the rock apart |
| 29.) explain how oxygen causes chemical weathering | iron combines with oxygen and water to form chemical weathering (oxidation) |
| 30.) Predict how the city's climate will affect the weathering of the statue. Give reasons for your prediction. | because of the pollutants 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. the statue will not last long in the U.S city. |
