| acid rain causes very rapid _________________ weathering. | chemical |
| the most important agent of chemical weathering is __________________. | water |
| after chemical weathering the 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 _______________. | erasion |
| the rate of mechanical 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 rocks 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 |
| what is the agent of mechanical weathering called in which rock is worn away by the grinding action of other rock particles | hot |
| what kind of weathering causes the mineral composition of rocks to change | chemical |
| what type of climates causes weathering to happen rapidly | hot,wet |
| what is ice wedging | water freezing in rock and breaking aport |
| what is uniformitarianism | the same process that happened in the past is happen today |
| why does a permeable rock weather easily | it has tiny airspaces that allows water to seep in the cracks |
| what can scientists infer from the rounded shape of the Appalachian mountains | they have been weathering for many years |
| describe how freezing and thawing of water causes mechanical weathering | freezing and thawing |
| explains how oxygen causes chemical weathering | iron conjoins 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 | the pollution and would make acid rain the fastest weathering occurs in hot and cold climates. |
