Questions for test Make sure to study
| Question | Answer |
|---|---|
| Some plants produce acids which result in______weathering | chemical |
| A rock that contains tiny,connected spaces through which water can move is said to be .... | permeable |
| One agent of chemical weathering is ____ which combines with water to form carbonic acid | carbon dioxide |
| 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 ____ waethering | 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 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 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 activity result in | mechanical weathering |
| What is an 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 and rocks |
| What is uniformitarianism | Something that happened in the past that is still happening today |
| Why does a permeable rock weather easily | Because 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 | Because they are rounded 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 causes mechanical weathering | Water freezes in rocks |
| Explain how oxygen causes chemical weathering | Iron combines with oxygen and water to form chemical weathering |
| 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 ice wedging. |
