questions for test
| 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 |
| The actions of animals most commonly can cause the type of weathering known as __________________ | MECHANICAL |
| Rapid chemical weathering can be cause 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 and climate |
| Acid rain causes very rapid ___________________weathering | chemical |
| The most important agent of chemical weathering in __________ | water |
| After chemical weathering, the chemical makeup of the weathered rock is _____________than the original rocl | 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 weathering is ________________faster 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 rocks farther apart are in agent of ______________weathering | mechanical |
| What has a rock probably been chemically weathered by if it contains iron and becomes soft, crumbly, and turns reddish brown in color?____________________ | oxygen |
| What may the growth of plant roots and animal activity result in?______________________ _________________________ | mechanical weathering |
| 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?___________________ | cold/dry |
| What type of weathering causes the mineral composition of rocks to change? | chemical |
| What type of climate causes weathering to happen rapidly? ___________________________________ | hot and wet |
| Water that freezes int the cracks of rocks forcing them further apart and to eventually break into pieces is called________ ________________________________ | ice wedging |
| The same process that has happened inn the past and is still happening today is called/______________________ | uniformitarianism |
| Why does a permeable rock weather so easily? ________________ | They have air pockets that allow the water to seep in and weather the rock from the inside as well as the outside |
| What can scientists 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, and acid rain |
| Describe how freezing and thawing causes mechanical weathering___________ | Water seeps into the cracks in the rocks, freezes and expand causing the crack to widen, ice thaws and water seeps down into the crack more repeating the processes. |
| Explain how oxygen causes chemical weathering_______ | Oxygen mixes with water to form oxidation |
| The city has hot rainy summers, freezing winter temperatures, and air pollution from the burning of coal in a power plant. Predict how the city's climate will affect the weathering of the statue. | Water could seeps into cracks and freezing and thawing could cause ice wedging to happen, acid rain cause from the pollution from the burning of coal could weather the statue, and weathering happens the fastest in hot and wet climates. |
