rocks and weathering
questions for test
| Question | Answer |
|---|---|
| some plants produce wethering | 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. | carbondioxide |
| the actions of animals that most commonly can cause the type of weathering known as | mechanical |
| one agent of chemical can be caused by which is rain combined with pollutants | acide rain |
| some plants produce acid that result in weathering | chemical |
| the factors the rate of weathering are the type of and the | rock and climate |
| acid rain cases very rapid weathering | chemical |
| The most important agent of chemical weathering is | water |
| after chemical weathering, the chemical makeup of the weathered rock than the original rock | different |
| frizzing and thouging 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 a hot wet climate than in a cold dry climate | 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 been chemically weathered by if it contains iron and becomes soft, crumbly, reddish brown in color? | oxygen |
| what may the growth of plant roots and animal activity resolut in | mechanical |
| what is the agent of mechanical weathering called in which the rock particles are worn away by the grinding action of other rock particles? | abrasion |
| grinit will last along time if it is used for building in what type of climate | cold |
| what kind of weathering causes the material composition of rocks to change? | chemical |
| what type of climate cases weathering to happen rapidly? | hot and wet climate |
| what is ice wedging? | water freezing in rocks to act like a wedge to bak the rock apart |
| what is uniformitarianism? | the same process is happening today as in the past. |
| why does permeable rock weather easily? | air holes |
| what do scientists infer frome the rounded shape of the appalachian mountains | they have been withering longer |
| a marble statue is left exposed to the weather. what agent of mechanical weathering probably will cause it to whether? | freezing and thawing |
| describe how freezing and thawing of water cases mechanical weathering . | when water freezes it expands. |
| explain how oxygen cases chemical weathering. | oxygen mixes with water to for oxidation |
| predict how the cites climate will affect the weathering of the statue. give reasons for your production | some of the reasons why the statue mayweather is because of the pollution and the wet climate would cause acid rain the hot or wet climate may result in frizzing and thugoing |
